This image was a little more in my area of experience lighting wise so I set the camera how I though it should be and fired with the flash comp on -1.
I knew we were all sweating from hiking down to the river and I also new my head is really shinning and loves to blow out in pictures
I decided to purposely underexpose this a little bit by exposing at 0 exp comp. My camera on default seems to be 1/3 stop dark so +1/3 is IMO true 0.
Also based on the tests Kelly has been doing I knew my flash comp should be higher in order to fill in the my eye sockets, but I also knew the flash would probably blow out are sweaty faces.
Anyways, here is the result right off the camera. You can see me (middle) and the guy to camera rights heads are just about blown, but not. and the eye sockets are dark. A total compromise, but I would rather recover the she shadows in the eye area than have a blown out head

Gatta love the self timer mode also
