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

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.

\$\begingroup\$ 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. \$\endgroup\$ Commented Dec 19, 2011 at 17:35

\$\begingroup\$ 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). \$\endgroup\$– seanmcCommented Dec 20, 2011 at 1:38
