Looking to understand why when I use my d7100 to fill in foreground with flash that everything is blown out. When I had a cheaper Nikon DSLR to fill in foreground, I was able to do so with great precision and with no extra adjustments-- just pressing the flash button and adjusting distance to fill in. When I attempt to do this with the 7100, everything is massive overexposed in aperture mode. Thanks for advice!
