Adobe Raw question.

What's the difference between Exposure and Brightness in Adobe Raw Processor ?

Exposure controls the white point. Brightness controls the intensity of the image and has less effect on the white or black points.

 

Hold down the option key ( or equavalent in pc) as you move the slider and when you see the white appear, that will overexpose. Alturnatively, turn on the small square on the histogram top right and move the exposure slider, when it turns red you will get clipping or overexposure.

 

See The Radient Vista, video tutorials tab, Photoshop 101, lesson 5 or 4. Site is down temporarily now or I would provide a link.

Stated differently, "brightness" targets the mid-tones and has diminished effect at the extremes of the histogram. "Exposure" slider moves everything from black to white toward the right edge of the histogram in roughly uniform fashion.

Interesting - I never use Brightness, but it's nice to have an idea of how it works.

 

How would you compare Brightness to Fill? (which I do use)

[godfrey]

Fill and brightness controls are close in operation but not identical. Brightness shifts the whole tonal curve between the

black point and white point settings where fill adjusts only the lower third to half of the tonal curve.

i've recently started using brightness to partially replace using fill. I find using less fill and more brightness gives a more natural looking image.

Thanks. Maybe it's time to revisit brightness.
