[Photography] How to Use the Filter in Lightroom’s Library Module

Once you enable the filter in Lightroom’s library module, you are able to search your images in three ways – text, attributes and metadata. To activate the filter bar, the keyboard shortcut is backslash (\). The filter bar will be activated and displayed on top of the workspace (see the screenshot below), only if you press the backslash key in the Library module. If you press the same backslash key in Develop, you will be see the before version of the selected image, provided you have made some corrections to your image.


Lightroom FilterBar None 01


Filter by text


The first option, Text mode allows you to search your images by the images’ text fields, from title, caption, keywords, searchable metadata, searchable IPTC, searchable EXIF, to any searchable plugin field. The field box comes as a drop down menu, where you can pick the text your search should be based upon.


Lightroom FilterBar Text 02


In the next box you can pick either one of the following parameters – contains all, contains, contains words, or doesn’t contain. You can select starts with or ends with as well. In the last box you can enter your text, the text which you want your search should be based upon.









Searchable Contains all

Filter by image attributes


The next option to filter is based upon the Image attributes. This section is further divided into flag status, ratings, color ratings and kind of file. In flag status, you can either pick flagged, unflagged, or rejected ones as well as a combination of two of those choices by clicking the flag symbols. Once you filter your images, the selected ones will be highlighted in white (use Ctrl/Cmd+A to select all).


Lightroom FilterBar Attribute 03


Filter by rating


Lightroom FilterBar Rating 03a


The next option in this section is star rating; you can filter photographs based on the number ratings you have applied to them. You can click the third star if you want to filter the photographs which have three stars exactly. You can also select less than or greater than by clicking the greater than symbol (>), where you will be prompted to select one of the following:


Greater than


Filter by color label


The next option in this section is filter by color label; you might have applied color labels based on your own methods of flagging images. For example green for web upload, red for yet to process, or something like that. Imagine you want to view only the red ones which you wish to process now. You can do that by clicking the red color box alone or you can add yellow along with it by clicking that box as well. In this way you can combine all the color labels, or only the ones you want. If one color label is selected, that particular box will be brighter than the other, which means it is active.


Color filter


Filter by kind of file


The last option in this sub-section is to filter by kind; which in this instance means the kind of file. In Lightroom you can have three kinds of files; master image files, virtual copies, and video files. If you want only the virtual copies you can select that particular icon alone. Like the other filters here, you can also combine more than one choice.


Filter by metadata


The most powerful option to filter your photographs is by metadata – the options are endless.


Lightroom FilterBar Metadata 04


You have the option to filter your photographs by all of the metadata in your files, you can get an idea by looking at the screenshot above. You can combine multiple metadata together to work for you by adding more filter columns. Click the right side of the title for an option to add more columns with other criteria. Click the filter title itself to change it to something else. In the screenshot, I have clicked the title Label ; and you can see the pull-down menu of options that appeared.


Lightroom FilterBar Metadata 05


Miscellaneous other filtering tips


The filtered photographs based on your criteria will be instantly displayed on the below workspace. You can also combine multiple filter sections from Text to Attributes to Metadata or all together, the options are almost endless.


You can create presets if you have a particular way of filtering your photographs, provided you have managed your library in that way. Have you noticed the lock symbol on the right end of the filter bar? The drop down menu next to the lock symbol has an option to save your search as a preset, so next time you just have to select that preset. Easy right?


Save filter


The lock symbol at the right end of the filter bar will lock the filter criteria (if you click it) and the same filter can be applied to all your collections or folders one by one as you select the folders and collections.

I hope this article helps you work smarter with Lightroom and saves you lots of time and resources.


Cheers and happy photographing.
