When taking a photo where there is a primary subject, the primary subject should often occupy the central 60-80% of the total image with a little (10-15 percent) on the left, on the right, on the top and on the bottom. Keep the primary subject in that central area and the photograph will appear to be balanced and instantly signal to the viewer where attention is to be drawn.
Do not try to force too much into the image. If you have a lot you “must” capture, take a wide angle of everything then do a series of quality pictures of the highlights. (Recall the previous hints of putting them in a sequence of left to right, and of the wide angle shot followed by medium distance followed by close ups.)
On the other hand, do not allow the primary subject to become too small by leaving too large of a border. There is not usually much value in showing extra sky or ground when you have a primary subject being the reason you want to keep for your memories
Boldly fill the central three-quarters of the total image.
