I have a Nikon D80 and I was wondering how to create three or more different exposures. I have a tripod and the software to create a HDR photo, but I still need a way to get 3+ images of different exposures. I THINK I need to put it into manual mode and leave the aperture the same and adjust the shutter speed to change the exposure. Also, my tripod is not very steady and when I adjust the shutter speed or click the shutter it often bumps the position of the image. I was considering getting a wireless remote control to take the pictures, but I still bump the camera when changing the shutter speed. Also should I change the shutter speed only or is there something else I should be doing? Also, I have Photomatix Pro and I wanted to know if this was one of the better programs for HDR? Any suggestions and help would be greatly appreciated.
