Key concepts

The lesson

Non-destructive editing keeps the original pixels: use adjustment layers for brightness, contrast and colour, and masks instead of erasing.

Correct exposure first, then white balance so whites look neutral, then overall colour.

Keep layered source files and export flattened copies for use.

Step by step

  1. Open a photo and add adjustment layers.
  2. Correct exposure and white balance.
  3. Mask an adjustment to one area.
  4. Save the layered file.

Practice activity

Correct the campaign photos non-destructively.

Expected result: Corrected photos with editable layers.
