The short answer
Why use Exposure?
Color fixes are easier to judge one change at a time. The live preview shows blown highlights, muddy shadows, or a color cast before you save.
The slider is in camera stops. 50 is unchanged, 25 is one stop darker (half the light), 0 is two stops darker, 75 is one stop brighter (twice the light), and 100 is two stops brighter. Every pixel is multiplied by the same factor, like opening the lens or slowing the shutter.
Brightness uses even steps from 0.25 to 1.75 times, so its top end is gentler than two stops of exposure. Gamma keeps black and white where they are and moves only the midtones, which is the better choice when the shadows are dark but the sky is already bright.
Raising exposure cannot bring back a sky that is already pure white, and any highlight pushed to white stays clipped in the download. If bright areas start losing detail, step back and lift the shadows with Gamma instead.

Exposure tips
- Around 62 is half a stop brighter, often enough for a dim indoor shot.
- Pure white areas stay flat; lowering Exposure turns them gray without bringing back detail.
- If faces are dark but the sky is fine, Gamma lifts midtones without clipping highlights.
- Brightness tops out at 1.75 times, while Exposure at 100 multiplies the light by four.
