What is the difference between using Fill Light and Blacks sliders and dealing with the Exposure slider directly in Adobe Photoshop Lightroom?

share|improve this question

Exposure: Adjusts the entire image lighter or darker.

Fill Light: Lightens the dark regions to recover detail, but leaves the bright regions alone.

Blacks: Darkens the dark regions.

Recovery: Similar to fill, it attempts to recover detail in the bright regions, leaving the darker regions alone.

Fill and recovery, if I understand them correctly, are better than simple histogram shifters. They understand image information outside the dynamic range you are currently viewing. Some software calls this "expanded dynamic range" but I think Adobe soft-pedals it. In any case, it can give you an extra edge if you have an exceptionally contrasty image of if you just missed on the exposure. – Steve Ross Dec 19 '11 at 17:35
Also, if you watch the histogram while using the slider for each control, it highlights the main area of the histogram to be affected (though I don't think it ONLY affects that area). – seanmc Dec 20 '11 at 1:38
