Sunset available light, fill in flash

Available light at sunset plus fill in flash

Still looks a bit dark unfortunately. I might also have tried to get the clear space behind your subject to surround the head rather than the obvious foliage branching out from behind the head. Hopefully you can either try this again or work with it in an image processor of some sort to clean it up?

Looks like the fill flash and sky are balanced about right, but the whole thing is too dark/underexposed. Or bring up your fill flash some more. Could easily be fixed in Photoshop or whatever editing software you use. Another possibility also if it looks right on your computer and then looks dark when you upload it here, that may be because f you are shooting in AdobeRGB color space and then save to web which uses sRGB -- I think that can cause things to look too dark.

It looks a little dark on my computer as well,I adjusted it in levels, thanks for sharing the photo,she has a nice smile.
