Your photo looked great in person

On screen it's gray and tired, and you're not sure which slider to blame.

Most guides tell you to flatten everything and hope. Then one change later, you can't undo the last three.

It's easier than it looks, once every edit has its own layer.

What's inside the guide

You edit photos a few evenings a week. You've outgrown one-tap filters, and you'd like to understand layers, curves and masks. You don't want a monthly bill or a big install, and you'd rather your photos stay on your own device. This guide is for you.

  • Six short steps with a quick check after each one
  • How to add contrast with a gentle S-curve
  • How to remove a color tint
  • How to fix only the sky, or only a face, with a mask
  • How to add depth with one blend mode
  • A 6-point checklist to keep next to your screen
