I have watched many photographers set up there tripod. Compose the shot and take only one shot and leave. I don't understand how one shot would be enough. I have always taken at least 6 shots when I was shooting slide film. Now that I shoot digital I take many and I still don't think I have enough. One day I found some Pink Pyrola growing along the pond. I had never seen it grow anywhere else where you could count plant after plant. Before I even took any shots I looked over each flower searching for the right one. So I have often wondered how many shots is enough. No one flower is the same and each year they may look the same, but they differ a little. The way the light hits them or dew on them...so how many is enough? I think for most it is an easy question.
For me one shot is never enough.
