Layering of Fixes and Effects
When you’re in Edit mode, you can apply multiple enhancements and special effects to your photos. You don’t get layers per se like you do in Photoshop, but you can stack the effects. Each time you apply an effect, you’ll see a small check mark next to the effect in the Edit list on the left. If you’ve applied multiple edits, you can deselect the checked box of a particular effect to see what your photo would look like without it. It’s kinda like layers, but not really—but still really cool.
