??? I do not understand this? If you set your camera to close to the ambient light and set the flash to ttl it will just fill in, if you select a wide aperature you get shallow DOF and pick up more ambient light, if you select a small aperature and "kill" the ambient you get what is lit by flash only.
Look at : http://homepage.mac.com/whmcclary/PhotoAlbum16.html and look at the photo of the girl looking into the pumpkin. This photo was made on a Canon D60 at 1/2 second flash at -2 using a 420 ex and ETTL As I think you can see the flash just filled in...I just set the aperature and shutter speed where I wanted to, 3.5 and 1/2, and let the flash do all the rest. In the old days you were stuck with what power levels the flash had programed now with TTL you can select any aperature and the flash will fill in automatically...any level of ambient is decided by you the photographer. To get this flexiability in the old days you had to have a vari power module and a flash meter to get it just right...now it is a no brainer.
