Do you ever wish that you could just quickly look through Library’s Grid view for photos of a particular subject at a particular angle… or even just photos of a particular subject? Then you wouldn’t have to go through dozens or hundreds of pictures when you were just looking for a particular type of thing.
Of course, the most common way to take care of that problem is to just drag all the similar pictures into a sequence by “light-tabling” them. To do that, first make sure that you’re in User Order sorting. Then you just click the center of the picture to select it, then drag it next to another similar picture in the grid. The original thumbnail will appear in the new location. To speed things along, you can Cmd/Ctrl + Select any other related pictures you see in that one view of the Grid and drag them next to another of the similar pictures. After repeating that process a few time, you have groups of similar or related pictures that are all side-by-side.
The problem is, you may still have to scroll through several grid screens (or spend a lot of time dragging the film strip back and forth) to find the picture group you’re looking for. To cure that problem, all you have to do is to select any group of related picture and then designate that selection as a stack. The first picture in the selection will be the picture you see in that grid panel. The others will be stacked beneath it. So now you just see one picture representing the whole group, which could be hundreds of pictures.
Here’s all you have to do to get it that way: In the Grid view, follow the instructions in the first paragraph to drag all the photos into the groups that you want to have in each stack.Next, select all the photos and press Cmd/Ctrl + G. All the pictures will be hidden beneath the first picture and you’ll see a small number in the upper right corner of the picture. Then, later, if you want to find a particualr picture, just expand the stack by .
Now any time you want to see all the pictures in the stack, just tap the letter S. You’ll see all the images side-by-side in the grid.
You can also have stacks within stacks. That’s important because Lightroom can be asked to automatically stack images that are variants of the same image, such as multiple “exposures” of a RAW file or files that you’ve done additional processing for in Photoshop. You’ll probably want it to work that way. All you have to do is to include that automatically made stack within the stack you make by subject type. When you open the subject-type stack, you’ll see the individual stack and you can then open them.
