yes, two flashes offer twice the power of one flash. Or if you turn them to 1/2 power you get the same power as one flash at 1/1, but way faster recycle, and way faster flash duration. Pretty much just better overall.
Do you spend much time editing the photo afterwards, with white balance, saturation and your levels etc?? And is this just a one shot, its not HDR with the sky or anything? (:
Which is what I'm (supposedly) studying! I've just got to get an injury healed and get the most irritatiinly tiny bit more money together for a new cam and get out there, would I be right in thinking that practice makes perfect with both film and photography?
