Andre Gunther has a nice little article featuring the “ten most common photographic mistakes“, which is definitely worth a read.

All Andre’s tips are based on the composition of your photos, which fits in nicely with our own Creative Composition series. It also means the advice is useful for everyone - whether you have the cheapest compact digital camera or a top of the range SLR.

My own tip to add to this: If you’re shooting on digital, always take several photos of your subject, trying different angles and composition techniques, and never delete photos from the camera unless you really need to. You’ll often find unexpected surprises when viewing your photos on a large monitor that are easily missed when viewing on a camera’s tiny display.
