And information continues to leak, including recent Canon EOS M7 specifications; if the rumors are accurate, it’s shaping up to be one impressive camera.
Unfortunately, the same set of rumors also puts the EOS M7 price at $1599 USD, which is significantly more expensive than either the EOS M50 and the EOS M6 Mark II. But if the EOS M7 is, as many have speculated, a higher-end, durable APS-C mirrorless model from Canon, this pricing could make sense.
Now, the features listed above are unconfirmed (Canon Rumors marks them as CR1), so take them with a pinch of salt. But the EOS M7 has long been a topic of discussion, including speculation of the camera as a mirrorless replacement to the Canon EOS 7D series, which was a favorite set of DSLRs among bird and wildlife photographers.
If the latter is true, the EOS M7 should, first and foremost, be an action photography camera. This is hinted at by the (relatively) fast continuous shooting specification, as well as the dual card slots, but we’ll have to wait and see regarding its durability (the 7D series was known for its large, tough bodies).
Interestingly, Canon Rumors also mentions the possibility of the EOS M line drawing to a close in 2021, with Canon focusing entirely on the EOS R lineup, including (perhaps) an APS-C EOS R model. If such a rumor were true, then the EOS M7 and the EOS M50 Mark II may be some of the last EOS M bodies we ever get.
Of course, this is also completely unsubstantiated, so just keep an eye out for related news in the future!
Now over to you:
What do you think about the rumored specifications for the Canon EOS M7? Is it a camera you’d be interested in? Also, do you think that Canon will truly discard its EOS M lineup? Share your thoughts in the comments!
The 50mm prime lens, commonly known as the Nifty Fifty, is a lens that even inexperienced photographers have likely heard of. Most of us know it for its outstanding qualities; it’s an inexpensive, high-quality, prime lens that is in plenty of photographers’ bags around the world and is one of the most popular lenses of all time.
What we might not think of a Nifty Fifty as, however, is a lens normally used for landscape photography. The field of view is tight, and the lens doesn’t possess a focal length wide enough to usually be considered proper for this sort of work.
But I have. For four years, the 50mm f/1.8 has been my workhorse for portfolio building (which is primarily nature and landscape), and even though I’m branching off with other lenses, I can’t stress the usefulness of the Nifty Fifty. And I’m not alone.
My primary reasoning for using the 50mm instead of going out and buying a proper wide-angle lens such as a 35mm or even wider?
Cost.
I was diving back into photography, and I was on an extremely tight budget. After buying my camera, spending $500 on a lens simply wasn’t an option. It didn’t take long for me to hear my fellow photographers sing the praises of this wonderful lens: cheap, fast, and sharp. Right up my alley.
There are no tricks or immaculate revelations here, and you won’t likely become famous for taking only landscape shots with 50mm lenses. But there are a few reasons why shooting landscapes with a 50mm lens can produce great results.
Giving it a try can only improve your photography and make you a better observer of the world around you.
Focus on what’s important
We think of landscapes as sprawling, wide shots that include many elements in one frame, but do they have to be that way? Can we not capture the beauty of the area around us in a tighter package? The rolling hills and an interesting tree in an outdoor scene are more than enough to create a photo that provokes thought.
The Nifty Fifty makes it easier to focus on whatever is most important in your photo, while still capturing enough around the subject to lend the shot scope.
Shooting at this focal length forces us to focus on the most important parts of what we’re seeing around us. Trimming the fat, as they say. In doing this, we’re also training ourselves psychologically to do the same in all of our shots.
Quality
Landscapes usually require very good sharpness, and 50mm prime lenses excel at that. No extra moving parts normally required for zooms makes for a crisper, sharper result. As with most lenses, the Nifty Fifty sweet spot isn’t wide open, but more in the f/4 to f/5.6 range. And narrower apertures will still yield excellent results.
The 50mm prime allows you to capture very sharp images.
Take your time
Since the 50mm is a prime lens, you’ll get an added benefit (or detriment, depending on how much you care for walking): The single focal length means you can’t just shoot from anywhere. Instead, you’ll need to move around to find the best angle and distance. This automatically forces you to think about your shot a bit more, which is always a good thing.
A 50mm lens allows you to think differently about the landscape or subject you’re framing and to make more creative choices.
With a zoom, you’d adjust focal length without even thinking until the scene is framed in a way that looks good. But what if that isn’t the best angle or distance? The Nifty Fifty will give you the incentive to take a chance and try something different, whether it be an angle, a distance, or a perspective.
No wide angle…or can there be?
Of course, there can! The 50mm gives you a gentle push into playing around with some panoramic shots. Three, four, five, or more shots can be stitched into a flattering wide-angle composite, sometimes with even more dramatic results than a single wide-angle shot.
By stitching together shots, we can create a panorama that gives us the wide field of view we’re looking for.
Lightweight is king
If you’re serious about landscape photography, you’re probably already lugging around a considerable amount of gear. Camera bodies, other lenses (you don’t go out with just one lens, do you?), tripods; the list goes on.
The last thing you need is more heavy lenses when you’re out and about, right? Do you know what the Canon 50mm f/1.8 weighs? 4.6 ounces (130 g). It’s short, sweet, and light to boot.
At the end of the day, all lenses and focal lengths have advantages and disadvantages, and the case can certainly be made for using wider glass. But, as a teaching tool, the 50mm prime lens is a great option for your landscape photography; it will make you think a bit differently about your photos and easily provide you with clear, sharp images.
Ed Verosky is a professional photographer and author based in New York. In this article, Verosky explains how to create portraits using natural and ambient light only. To learn more about achieving great lighting in any situation, check out Verosky’s popular eBook, “100% Reliable Flash Photography.“
Note: This post contains one image with very mild nudity (in fact, so mild you might not even see it).
For me, using flash can be the most efficient way to create a high-quality portrait. There’s nothing like it for an editorial shoot when you need that combination of full lighting control, minimal shooting time, and predictable results. Sure, you have to know what you’re doing to make it come together like that. But that ability comes with knowledge and experience.
Mastering flash means mastering your light in any situation. Sometimes, however, there is beautiful light to be found, just waiting there for you to use it. Natural and constant ambient light can be your best friends if you have a little time and flexibility with the environment and your subject.
Constant light, as opposed to flash/strobe lighting, will allow you to see and adjust its effect on your subject and the environment in real-time. This is a great way to learn about lighting placement and this knowledge and experience will certainly carry over into your flash portraiture. As I like to say, “light is light,” meaning that the principles of lighting a subject and the environment are essentially the same whether the light source is a quick “flash” or a constant illumination.
The main difference is that the flash is capable of producing a more intense light but with too short of a duration for the photographer to see the effects of its position on the subject in real-time. With constant lighting, you can casually move the lights and your subject around and know instantly how the changes will affect the portrait you’re making. With a few test shots to check exposure, you’re good to go.
Lighting setups
Natural light. Window light is just about the most beautiful light you can find when the conditions are right. It can serve as a huge softbox and be manipulated with any combination of window dressings such as blinds and curtains. Simply place your subject nearby the window and let the light create much of the portrait’s drama. I like to position the subject so that there is plenty of shadow to one side, providing many options for classic portraiture looks.
Window light narrowed with curtains. ISO 800, 50mm, f/2.8, 1/80 sec.
Household lights. You can also make great use of simple household lamps. I like to remove the shades off the room lights and utilize them as bare bulb light sources. To start off, just position the main light in front and to one side of your subject, preferably several inches higher than their head. This will give you a classic lighting pattern to work with. A second light may be placed farther back from the subject and serve as a backlight or kicker, which will add dimension.
A setup consisting of two household lamps, minus the lampshades. The kicker is behind Kelly ,and the main lamp is almost directly in front of her, just to camera right. ISO 800, 50mm, f/2.8, 1/60 sec.
Camera settings
My general advice for any indoor shooting is to think “fast and wide.” Your initial camera settings should be a balance of the highest ISO possible that will still provide acceptable noise levels for your purposes, the widest aperture your lens will allow, and the fastest workable shutter speed.
Of course, each of these controls is interrelated and integral to overall exposure, so you’ll have to make some adjustments and concessions for the environment you’re working in, and for the effect you’re trying to achieve in your shots.
Fortunately, most DSLRs are now capable of low noise even when using high ISO speeds, so most room lighting and even low natural light won’t be a problem for you. But even if your camera happens to produce lots of noise at higher ISOs, that isn’t necessarily a big concern. Either leave the noise as is, or bring some of it down in post-processing using your choice of available noise reduction techniques.
Many photographers actually artificially add noise back into their images in order to reproduce the look of film, or otherwise reduce the super-clean, slick, digital look coming out of the camera. Simple advice: Don’t worry about the noise unless it gets in the way of the image you’re trying to create.
Another thing that will really help with achieving beautiful portraits in lower lighting situations is a fast lens. By “fast,” we’re referring to a lens with a wide aperture of at least f/2.8. The wider the aperture, the more light the lens allows to pass through in a given unit of time. This will give you more freedom with your ISO settings (as they won’t have to be so high to compensate for less light coming in through the lens), and faster shutter speeds (as they won’t have to be so low to compensate for less light coming in through the lens). Lenses with wider apertures also have the capability of shallow depth-of-field, which can greatly add to the interest and mystique of your portraiture.
Shutter speed is an important consideration not just because of its effect on overall exposure, but also because of potential blur with lower shutter speeds. As with ISO, however, the effect of supposedly less-than-optimal shutter speeds is what you make it. You might find an occasional blurry image makes a rather artistic statement. Every portrait doesn’t have to be as sharp as a tack.
Another household lightbulb setup, featuring Chris. I used a bare household lightbulb off to camera-left to illuminate her on one side and the background at the same time. The main light is coming in from camera right. ISO 800, 85mm, f/1.8, 1/60 sec.
So, with those factors in mind, you might want to try the following exposure combination as a starting point and adjust according to your needs:
Camera Mode: Aperture Priority
Aperture:f/2.8 (or the widest possible for your lens)
ISO: 800
Shutter Speed (target): 1/100 sec. or higher.
In Aperture Priority mode, your camera will automatically set the shutter speed for you while you control everything else. You’ll have to pay attention to your shutter speed to make sure it isn’t falling so low as to create unwanted blurring. Again, these are just starting points. With a stationary pose and a steady hand, I’ve managed handheld shutter speeds as low as 1/15 sec. and produced good results. You might also want to try your camera’s Manual mode to maintain full control of your settings. If your lighting conditions are going to be fairly static, I’d recommend it.
Also, you will most likely benefit from shooting in your camera’s RAW (NEF) format so that critical adjustments, like white balance, exposure, and contrast, can be made easily and with minimal loss of information in post-processing. Although white balance settings aren’t actually imposed on the RAW file, you can set white balance as you wish during shooting in order to get an idea of what the final image might look like. Plus, a chosen WB setting will tell your processing software what color temperature and tint settings to best start off with for each image.

Post-Processing
Aside from the creative post-processing possible with your ambient light images, there are some things you might want to address in the initial post-processing effort:
White Balance: Not all light sources produce the same color temperatures. Despite what they look like to our eyes, the camera will record various types of household lighting (fluorescent, tungsten, daylight balanced) and natural light (sunset, cloudy, shade) as producing different color casts.
So if you are shooting a portrait using a bright tungsten light as your subject’s main light, but you have a strong window light coming through in the background, you might have an undesirable color mix to deal with.
Fortunately, you can correct these types of color mismatches in post-processing by making a general white balance setting choice in your software and selectively altering the offending colors in specific parts of the image. If this isn’t something you’d like to worry about, then don’t. The colors might be acceptable just the way they are. If not, you always have artistic color-altering effects and even black and white conversion options. So, it’s all good.
Noise Issues: I personally like a little noise in my images most of the time. But if you had to use very high ISO settings to get your shots, and have the need to bring some of the noise down, there are a number of good built-in, stand-alone, and plug-in software options to handle this. I will occasionally use the noise reduction tools in Lightroom or my Photoshop Noise Ninja plug-in, for example.
Natural and ambient light photography indoors can be a great way to learn the finer points of lighting your portraits. The actual experience for you and your subject is also worlds apart from the strobe and studio effect of working with flash. Unlike outdoor shooting, indoor work without flash can introduce problems having to do with lower lighting situations. Using some of the advice above, you should be able to handle the challenges of low-light portraiture and come away with great-looking images.
If you would like to learn how to get amazing light in any situation, check out Ed Verosky’s eBook, “100% Reliable Flash Photography.”It’s a great resource that has helped thousands of photographers improve their use of flash and ambient light for portraiture.
Our dPS Weekly Challenge this week is ‘Shallow Depth of Field’ #dPSShallowDOF
After our challenge last week, ‘Mistakes‘ it reminded me of when I first purchased my EF 50mm f/1.4 lens and pretty much had it at f/1.4 or ‘wide open’ the whole time! The shallow depth of field (Where you have your subject nice and sharp, and everything else out of focus, the quality of the ‘out of focus’ area sometimes referred to as ‘Bokeh‘) look was something I loved at the start, and as I learned to use it more effectively, became another ‘tool’ in my photography toolbox.
Shallow depth of field lets you isolate a subject or highlight an area in your frame, my first example below, highlighting the lens details on my new Sony 12-24mm, you see everything else nice and blurry – This was shot with another Sony lens, the FE 35mm f/1.4 (Maybe my favourite ever) it’s great for shallow depth of field!
You might not have a lens with a wide aperture (f/1.4 / 1.8 / 2 / 2.8, etc) but you can use whatever you have to go for the most shallow depth of field that you can.
We look forward to seeing what you come up with this week!

As the coronavirus crisis drags on, you may find that you’re getting out less to make photos. You could probably use some fresh and fun photo ideas as a pleasant diversion from the gloomy news. Whether you call these photo tricks, techniques, projects, or whatever, I suggest you give them a try and see what new and interesting photos you can make.
I think you’ll eat up these photo tricks with a fork and spoon! This is the last one in the collection, but be patient. Read the rest first, as there are some good ones; we’ll save this technique for dessert.
For a deeper dive
My intent here is not to get into great detail or give much “how-to” for these tricks. For some, I’ve already written complete articles and, where that is the case, I have linked to those articles so you can do a deeper dive into the subject.
For a few other tricks, I may not have written about them in-depth, but others have. The idea is that while these tricks may not be unheard of, this is a collection of photo tricks all in one place; it’s a jumping-off point for your photo exploration.
1. Bag a vignette
You may have heard of accessories called Lensbabies, a collection of adjustable and specialized lenses designed to give artistic, soft, blurred, and other looks to your image.
Now, I won’t pretend this trick will do for a few cents what specialized gear costing a few hundred dollars can do. But here’s a way to bag some interesting, Lensbaby-style images for dirt cheap.
This photo accessory costs a few pennies and easily fits in your pocket: the “Baggie Vignette.”
Here’s what you do:
Get a plastic sandwich bag and tear a ragged hole in the bottom of it. Pull the bag over your lens so that portions of the bag intrude into the edges of the image. Focus on your subject.
Viola, you have “Baggie FX.”
Play with the positioning, the size of the hole, various apertures, and lighting. Photo accessories don’t get any cheaper than this.
2. Bokeh with flair
Pronounce it how you like; bokeh refers to the look and quality of out-of-focus elements in a photo. Bokeh becomes especially noticeable when the out-of-focus elements are specular highlights.
Different lenses with different optics, different aperture blade shapes, and different numbers of blades will produce different kinds of bokeh, as will the photographer’s choice of aperture.
A wide aperture combined with out-of-focus highlights will give some nice bokeh effects. The pattern of the bokeh shape will depend on the lens. The Canon 50mm f/1.8 gives this kind of look.
Here’s a way to go a step further and make patterned bokeh. Lay a filter the size of lens you intend to use on a piece of cardboard, trace around it, and cut out the cardboard. Now cut a shape, such as a small star, into the center of the cardboard disc you made. Place the disc over the lens and tape it there, or sandwich it between the lens and a filter.
Here, a star pattern was cut in a “bokeh filter,” and the specular highlights in a piece of aluminum foil produced the star effect. Then the image was layered with another shot to create the final result.
With a wide aperture (a 50mm f/1.8 prime, the “nifty fifty,” works great), shoot something with some specular highlights and ensure those highlights are out-of-focus. The highlights will now be the shape of your “bokeh filter.”
Rather than make your own bokeh filter, you can also buy patterned bokeh filter kits with more elaborate shapes than you could probably cut yourself. For folks into 3D printing, this could also be a good project.
3. Reflect on this
You can take a still-life or product photo up another notch by shooting it on a reflective surface. You might think a mirror would be a natural choice for this, but because both the glass surface of a mirror, as well as its silvered backing, are each reflective, you will get two sets of slightly separated reflections if you shoot objects on a mirror.
A polished dark table proved just right for getting a reflection of the wedding rings. The jar of marbles was shot on a piece of black acrylic sheet and the bokeh effects were added with a string of Christmas lights in the background.
A better choice is a piece of acrylic plastic sheet, also known as plexiglass. You can get this in many colors, but I find a very dark black plastic sheet creates a look I like. (A piece of black tile would work well too, but I’ve not been able to find larger tiles.) Shoot with a black backdrop and you can isolate your subject nicely.
4. Big results with little lights
When we used film or less-sensitive digital cameras, big and often hot lights were needed for indoor photography. With the advent of LED lighting coupled with cameras offering low noise capabilities, we can now make images with very little light.
Also, when doing still-life photos, shutter speed can be anything you like: full seconds, or even minutes, if necessary. Now almost any lighting instrument can be used with some ingenuity. Small LED flashlights can also be used for light painting.
LED flashlights like these can be found cheap at the hardware store. The second image shows how they were used……to produce this image. Having limited light isn’t a problem when shooting still life where long exposures are fine. Canon 6D | Canon EF 24-105 f/4 | 3.2 sec | f/3.2 | ISO 100.
I have a collection of various flashlights (aka “torches”) and other LED lighting gear, which I’ve typically bought for just a few dollars online or at the local hardware store. Finding new ways to creatively use these little lights has allowed me to make some creative images. Take a look at this article which explores this topic further.
5. CD rainbow macros
Before you toss that scratched CD, add it to your bag of photo tricks. Mount a macro lens on your camera, or use whatever means you have to get close to your subject. Put the CD down with the reflective, non-printed side up. Then, with an eyedropper or other tool, place small water droplets all over the surface of the disc.
Waterdrops on a CD shot with a macro lens and lit in various ways can produce some colorful abstract images.
Focus your shot and get creative. The lighting is purely up to you. Perhaps try some shots in direct sunlight where the intense light will really pop the rainbow spectrum. Maybe try a small flashlight. Try a long exposure and light-paint the droplets. Anything goes when you’re making abstract images.
6. Oil and water abstracts
I wrote a complete article on this technique, which is another way to get some interesting and colorful abstract images. With minimal equipment and whatever lighting you like (even shooting outdoors with natural light), you can have a whole afternoon of fun.
Oil and water don’t mix, and that’s a good thing for this technique. A glass dish shot from above and through the mixture with some colorful objects in the background is the technique here.
7. Up in smoke
Add this to your collection of photo tricks to make some smokin’ hot images. An incense stick and some care with your lighting will get you going. Then take your shots to the computer where you can add additional effects. Have a look at my article here on DPS, “How to Make Interesting Abstract Smoke Photos,” for a full write-up on this technique.
This is a straight, side-lit shot of the smoke pattern rising from an incense stick.Take the straight shot on the left, mirror it in editing, and colorize it. Then you have a firebird! (At least that’s what I see. What do you see in this abstract?)The original smoke photo mirrored both horizontally and vertically and colorized in editing. Is this what they mean by “smoke and mirrors?”
8. Interaction with reflection and refraction
Find historic images of early photographers, and you might see them standing behind their cameras with black capes thrown over their heads. They did not have DSLRs, where the image entering the lens is reflected onto a mirror, through a prism, and then into the viewfinder right-side up. Instead, early photographers used the first “mirrorless” cameras, and the image came through the lens and displayed upside down on a ground glass at the back of the camera. The image was quite dim, which explains the need for the cape to better see the projected image.
The water-filled glasses refract the light while the black acrylic plastic sheet below reflects it. There’s a lot of light physics going on in these shots.
We won’t require you to take a course in optical physics so you can understand the behavior of lenses, light, reflection, refraction, or the differences in light transmission through various mediums. Just break out some glassware, pour in a little water, maybe use that piece of black plexiglass we mentioned earlier, find an interesting background, and go for it.
You are getting sleeeepy… The water in the glass refracts the light and flips the image, much like a lens.
These tiny glycerin drops act as little lenses, focusing, refracting, and reversing the image behind them.
9. Zooming around
In our collection of photo tricks, this one is hardly a secret. You probably have done it before. No? Well, if not, and you have a zoom lens, it’s high time you tried the zoom blur effect.
The technique is simple enough. Set your exposure so you can get at least a one-second shutter speed, if not longer. This ought to be easy enough at night if you set the ISO to its lowest setting (such as ISO 100) and stop down the aperture to a small size (such as f/16 or f/22). If you’re shooting in the daytime and these settings alone don’t get you down to a second or more of exposure time, try adding a polarizing filter or a neutral density (ND) filter to reduce the light still further.
Lights at night make great subjects for the zoom blur technique. You’ll definitely need to work on a tripod.
You can do this technique handheld, but a tripod helps. Set your camera so you get the 2-second shutter delay, then with one hand on the zoom ring, trip the shutter. When you hear it click, zoom in (or out) during the exposure. Play with starting zoomed tight and then pulling out during the exposure, or starting wide and then zooming in. Lights at night can make for great looks. Try only zooming during the first or second half of the exposure. There’s no single way to do this, so play and discover what you can create.
Both these shots were zoomed during the exposure. See my fireworks article for the “Boom, Zoom, Bloom” technique.
10. Create a computer screen background
An interesting background can add to the story of your photo. If you have a good-sized computer monitor and are shooting a smaller object, being able to create a background on your computer screen opens all kinds of possibilities.
Create a unique background to go along with the theme of your photo by putting up something appropriate on a computer screen in the background of your shot.
Photographing screens would seem a simple process, but can be more tricky than you think. If you plan to do much of this, reading up on the best camera techniques for shooting screens would be time well spent.
Cheaper by the dozen
The title said 10 photo tricks, but I’m going to throw in two more for free and make it an even dozen. I really like the looks I can get with these last two.
11. Action sequences with Microsoft ICE
I wrote the article “Make Easy Panoramic Images with Microsoft ICE,” which focused primarily on how to use this free and very powerful tool from Microsoft to make panoramic images. That is good fun in itself and a very useful technique.
Toward the end of that article, I touched on something else you could do with ICE: sequential action images. These are great for showing the progressive steps of action, and ICE makes the technique quite easy. Follow the link, read through the article, and see how you can make images like this:
Pan with the action while shooting multiple images in continuous mode, then use the free Microsoft ICE software to assemble them. Quite easy, actually!
Combine physics with fun and you get Phun, right? With this technique, you will be exploring what is called photoelasticity or, more specifically, birefringence.
Clear plastic tableware goes cosmic with this technique. Learn about birefringence.
You don’t have to understand what’s going on, and this isn’t hard to do. It just works and looks cool. Here’s what you’ll need to do:
Your light source will need to be an LCD computer monitor, TV or, for smaller subjects, a tablet, or even a cellphone. LCD screens emit polarized light, and using polarized light to backlight your subject is part of what’s needed to make this work.
Try to limit any other ambient light. The effect will be stronger if the LCD light is dominant in your shot.
Use subjects made of hard, clear plastic. Polystyrene is what is used for most clear plastic cutlery and drinkware, so these make good subjects. Often the plastic in cheap picture frames is made from similar materials. Glass objects will not work for this.
You will need a polarizing filter on your lens. Standard circular polarizing (CPL) filters work well.
Polarized light plus a polarized lens reveals the “mechanical stress patterns” within certain types of plastics. Clear styrene plastic usually works well.
Now, get ready to say “Wow!” Place your subject in front of the LCD light source. Bring up an image that will create a totally blank, white, bright screen so that light backlights your subject. You won’t see anything until you look through the camera viewfinder and through the attached polarized filter. Cool, huh?
Now rotate the filter. The computer screen will be white, black, or intermediate shades, while the plastic subject will show the rainbow birefringence effect. The patterns will be showing the mechanical stress within the plastic, with tighter patterns where the curves of the object are tighter.
Is it okay to still say “Groovy, man?” A second sheet of plastic was held in front of the lens, producing the colored background. Aside from some exposure and saturation adjustments, this effect is what you see through the lens while making the shot, not added later on the computer.
Just a tip when you are seeking potential subjects for this kind of photography:
Your LCD cellphone screen is a polarized light source. If you have a pair of polarized sunglasses, objects held in front of a blank white screen on the phone and viewed while wearing the glasses will show the effect if they are the right kind of material. You may have to tilt your head to get the same effect as rotating a circular polarizing filter.
Now go play
So there’s a dozen new things to try with your camera. You will also find that these kinds of photography will force you to use different exposure, focusing, camera control, lens selection, and editing skills than perhaps you normally might use.
Remember, even failed experiments can be lessons when you seek to determine what went wrong and then try again to get it right. Now go try some of these photo tricks, have fun, and post some of your images in the comments section. If you have any questions, feel free to post those, too.
Congratulations on your recent awards, too! It’s great to see members of our dPS community progress in their photography!
