What Dodge and Burn means

Dodge means brighten. Burn means darken. That’s it.

It comes from old photography where people manually controlled exposure on different parts of an image.

Today it works the same. You adjust light only where needed, not the whole image.

Why this is better than brightness slider

Most tools change the whole image. That is weak.

This tool lets you change only parts of the image. That is control.

• Brighten face without blowing out background
• Darken distractions without touching subject
• Fix uneven lighting
• Add depth and contrast manually

This is called local adjustment. It is one of the most important techniques in photo editing.

How to use it

You have two brushes:

Brighten → adds light

Darken → removes light

Pick brush size. Set strength. Paint.

Start soft. Low strength. Build slowly.

What this tool actually does to your image

You are not just making it brighter or darker. You are shaping how the viewer sees the image.

Dodging and burning is basically painting light and shadow manually. It lets you guide the eye exactly where you want.

That is why professionals use it all the time.

Real use cases

Portraits → brighten eyes, nose bridge, forehead. Darken sides of face.

Products → brighten product, darken background.

Drawings reference → make light direction clearer.

Landscape → control sky vs ground exposure.

You are literally sculpting the image with light.

Most important tip

Do not overdo it.

Good dodge and burn is invisible. If you see it clearly, it is too much.

Work slowly. Small strokes. Build gradually.
