I'm going to be taking photos for a native plant project. I'll mostly be dealing with overcast conditions (the Northwest) in a forest. And I don't want to use flash. I've been experimenting with different settings and was surprised to find that when I shot at 400 or 800 with shutter-priority (60), although the shots came out dark, I could make an easy Photoshop adjustment and the image came out looking OK. Aperture priority was the worst. And the Program setting was so-so. Using a tripod would solve a lot of problems, but there's usually some sort of breeze blowing through, so that wouldn't work. I'm shooting with a Canon Rebel XTi with a 17-85 mm lens equipped with image stabilization. any thoughts? I'll post some of the test shots if that would help. I just keep feeling that there are some bonehead-simple techniques that sub-bonehead me just doesn't see . THANKS!
