What am I doing wrong? I am a professional photographer. I have a Nikon D200. I seem to be able to get all my images in focus when I use my lights. I prefer natural light, and use the auto-focus, but like to manually set the ISO, shutter speed and f stop. Images have actually been out of focus when set at 1/160, and the F stop at F8, or F 11. But I have gotten portraits in focus in low lighting when I set my camera at 1/60, and F stop at 3/5! Something goes crazy when I photograph outside.
