I was working with an off-camera flash this weekend for some portraits of my son. I was shooting in medium sunlight (early morning, partly cloudy, w/ some shade), and I like the lighting control I got with the flash (it softened the shadows on his face), but it sort of messed up my aperture control.
Using a 30D w/ 50mm F/1.8, I can get a narrow DOF at low apertures, but since the use of the flash constrained my shutter speed, I couldn't use apertures low enough to produce as much bokeh as I'd have liked.
I'm thinking that one solution would be a neutral-density filter to let me use a lower aperture. Would this work, and if so, is this the preferred way to handle this situation?
