FOCUS - FOCUS - FOCUS

Poor focusing is one of the most common ways that photographs are ruined. Use the automatic focus of your camera, if you have it; usually, this is done by half-pressing the shutter button. Use the 'macro' mode of your camera for very close-up shots. Don't focus manually unless your auto-focus is having issues; as with metering, automatic focus usually does a far better job of focusing than you can.

Try an interesting angle

Try an interesting angle. Instead of shooting the object straight on, try looking down to the object, or crouching and looking up. Pick an angle that shows maximum color and minimum shadow. To make things appear longer or taller, a low angle can help. If you want a bold photo, it is best to be even with the object. You may also want to make the object look smaller or make it look like you're hovering over; to get the effect you should put the camera above the object. An uncommon angle makes for a more interesting shot.
