How is exposure different from brightness?

Exposure adjustment simulates the effect of changing a camera's shutter speed or aperture, scaling pixel values multiplicatively. Brightness adds a fixed offset to pixel values. Exposure tends to produce more natural-looking results for correcting photographs.

Can I fix overexposed (blown-out) photos?

You can recover some overexposed areas by decreasing exposure, but pixels already clipped to pure white (255) cannot be recovered since the original data is lost. For best results, always shoot with correct exposure in camera.

What units is exposure measured in?

Exposure is typically measured in EV (Exposure Value) or stops. One stop doubles or halves the amount of light. +1 EV doubles the effective brightness of the image.
