For Purposes of Elucidation, a collection of photos which reveal some mistakes in exposure, differences between in-camera JPEG and RAW processing, and whatever else I think of to comment upon. Note: I shoot in Adobe RGB color space; conversion of these to sRGB results in over saturated skin tones.

This first series are all in-camera JPEGs, no post-processing except the scaling down to 800pixel long dimension for posting on the web

Fursuiters: 0 Exposure Compensation, Fill Flash

Program, No Exposure Compensation, Fill Flash

The EXIF data is not showing any Flash Exposure Compensation. Note how badly washed out the left background wall has become. Flash is a 430EX II on an EOS 50D

Fursuiters: -1 Exposure Compensation, Fill Flash

Program, -1 Exposure Compensation, Fill Flash

Background wall is getting better, not much change on the fursuits; so the flash exposure appears to be compensating for the -1 background change.

Fursuiters: -2 Exposure Compensation, No Fill Flash

Program, -2 Exposure Compensation, No Flash

Well, the left background wall is now correctly exposed, but obviously with no flash at all the fursuiters are just a mass of fuzzy shadows. I believe the exposure that should have been set would have been -2 Exposure Compensation, with at least a +1 Flash Compensation to bring the whites of the fursuits "white".

A series shot at a recent wedding; I was not the official photographer. These illustrate in-camera JPEGs vs post-processed RAW, both scaled down to web-postable JPEG format. Aperture Priority at f5.6, Tamron 28-75 f2.8 on EOS 50D, 430EX II flash.

Wedding 1; JPEG

In-Camera JPEG, Fill Flash

I suspect that this is a photo where High-Speed Flash would have been better suited, presuming I was still within the working distance for that mode. Instead we see this rather overexposed shot since the shutter speed was maxed at 1/250s which is the fastest flash sync speed the camera supports.

Wedding 1; RAW

Processed (and lightly cropped) RAW, Fill Flash

I was able to pull out details in the whites which were blown out by in-camera JPEG conversion. However, the process did leave some harsh shadows, as if no fill flash had been used.

In Adobe Camera Raw, I had to adjust Exposure: -2, Highlight Recovery: 100 (maximum, this darkens just the top brightness levels), Fill Light: 22 (this raises just the darkest parts for shadows), Blacks: 15 (adjusts where the darkest black is). Essentially, Exposure, Recovery, and Blacks were all adjusted to make the image darker; Fill Light then was used to lighten the shadows.

Wedding 2: JPEG

In-Camera JPEG, No Flash

Wedding 2: RAW

Processed RAW, No Flash

Recovery: 18, Fill Light: 50

Not much needed for the highlight whites, the JPEG is almost acceptable for them; however, the shadows were significantly improved with the Fill Light slider.
