I've recently done some 'studio' photography for my club website involving members performing various kicks etc. and the photos have turned out okay, but could be better. Primarily they're a little on the dark and soft side. I'm using 2 tripod-mounted studio flashes with umbrellas, to each side at 45° in front of the subject, who is stood in front of, and on, a white backdrop. The camera (Fuji S9600) is tripod mounted directly in front with a shutter release cable. ISO is 80. Shutter speed is set to 1/640 (slower than this and the movement will start to show) and the aperture is set for a deep depth of field (I'm trying to keep a potentially forward or backward moving body in focus as much as possible). The camera is reasonably close to the subject so that I can keep the lens as wide angle as I can to let more light in. That's it. I've done as much as I can to try and balance out brightness and sharpness but am failing slightly on both. The images are being taken into Photoshop, and I'm having to do a reasonable amount of work to totally burn out the white background to achieve a hi-key effect. Can I do anything more with the kit I've got? am I doing something wrong? should I just accept that that's as good as I can do with what I've got to play with? Any advice would be greatly appreciated.
