An often overlooked feature of the Library Modules Grid view is the Painter Tool. Do you see that little spray paint icon in the Grid view Toolbar? If you don’t see it make sure you are in Grid view by pressing G, and if you still don’t see it then press T to make sure the Toolbar is visible. What? Still don’t see it? OK, click the drop-down arrow on the far right end of the Toolbar and make sure Painter is checked. Got it now? Good.
After selecting the Painter from the Toolbar to enable it (or go to Metadata > Enable Painting) you can load it with keywords, color label, flag state, star rating, metadata template, develop preset, rotation setting, or even a collection. Once enabled, the Toolbar will change to reveal the Painters options, so if you choose Keywords then a keyword entry field will appear, choosing Label will display the color label choices, Metadata will provide a list of all your metadata templates and so on. This tool can really help speed up an otherwise tedious task and even make it a little more fun. One of the ways I like to use this tool is when I am adding keywords to just certain photos within a folder or collection. It helps to already have a developed keyword list, but you can actually create new keywords this way too. Heres how it works:
1. Grab the Painter tool. Clicking on the Painter icon transforms your cursor into the spray can icon.
2. Click the Paint drop-down menu and choose Keywords from the list. In the adjoining field you can enter the keyword you want to apply. You can add multiple keywords by separating each with a comma. Press Enter to commit.
3. Click and drag the Painter tool over the photos you want to tag with the assigned keyword(s). As you click and drag the can animates to appear like it is spraying.
If you overspray and hit a photo you didn’t mean to spray you can hold the Option (PC: Alt) key to change the painter to an eraser, and click and drag over those photos to remove the sprayed keyword(s).
4. When you have finished with the Painter you can click the Done button in the Toolbar or press the escape key to exit the Painter tool.
The basic process works the same with whatever item you have loaded in the Painter, however if you are painting with a develop preset (settings) you can’t erase the overspray with the Painter tool. You’ll have to use CMD/Ctrl-Z to undo instead.
