Hi. I am shooting for mags- I came to photography after first being a writer- and I am getting these assignments where I have to freeze the action of a jumping billfish from approx 20-80 yards. I'm shooting with a D300 and 700, with the Nikon f2.8VR. In an attempt to get the best stop-motion pics, where the spray is suspended in midair, and no blur from the movement of the fish, I am using the highest shutter speeds I can. I've been in shutter mode; I jam the EV controls all the way up, which allows me to use shutter speeds up to 1/6400 of a sec, or if super bright outside, 1/8000. I'm shooting in RAW with the MB-D10 battery grip and getting plenty of frames per second.. My prob is, is that the depth that is in focus is VERY narrow- so narrow only maybe 8 inches is in focus. If, say, the fish's midsection is in focus, and the fish is facing to or away from me, often the front and back of the fish is out of focus. I look at other shooter's work and see that not only is the whole fish in focus- same type of thing I am shooting, jumping marlins- but some of the water ahead, and behind the fish, is in focus, and I'm envious. A hack like me is thinking, ok, try higher fstops- that will allow for more things to be in focus than such a shallow range (forgive me if I am using the wrong terms). Problem is, if I use higher fstops, I have to use slower shutter speeds, and I don't imagine I will have the same ability to freeze the motion so well. Thanks in advance for input.
