I found out something very cool today about my flash that I didn't know. Of course, my main mode is "oblivious", and it holds true here. Turns out, I can use my flash as a slave as well as a main flash! So I used the built in flash on my camera in addition to the big flash. It really helped reduce the strong shadows. Again, I did no Photoshopping here other than reducing the size of the file and adding my name.
