How many functions has your digital camera? 100, 200…more? How many functions do you use (or know)? But..I suggest to use only 3: time, aperture and focus. Why? Because for a good photo you have to concentrate on the composition…too many functions can distract. If I don’t want to risk to loose a snapshot, I set my camera with the following configuration: Program ( automatic aperture and time ) and Automatic ISO. Very simple! I’m sure to take a photo as soon as I put the camera to my eye.
