Know Your Resolution How you capture your photograph will determine the maximum size of the final print you can produce. Starting with a higher resolution Image will allow you to crop your photograph later and still have a sharp looking final product.

Use a Tripod A stable camera means sharper and clearer photographs. Digital cameras are very sensitive in lower light situations. If you turn the flash off thinking you'll capture some beautiful night scenes, you'll be very disappointed with the blur of the final Image

Purchase NiMH Batteries Long lasting batteries will allow you to take more photographs and not miss 'the' moment. An added benefit with rechargeable batteries is that they will save you hundreds of dollars and are good for the environment. The best type is NiMH (Nickel-Metal Hydride) rechargeable batteries and each one lasts approximately 500 times longer than a regular AA or AAA battery!

Passive auto focus: This is practically an electronic version of the way in which photographers manually focus on objects. In this mode the digital camera defines areas in the photo on which it will try to focus. These are usually around the center of the photo.

Active auto focus: Active auto focus is a more direct implementation of auto focusing. In theory if you knew the exact optical characteristics of the camera and its lens and the exact distance to the objects that you are trying to focus on – you could calculate the exact position of the lens that will result in a prefect focus

Combined auto focus: These systems are a combination of passive and active focusing. High end digital cameras support both passive and active methods. In combined mode the camera either chooses which system will work best for any given scene

Low contrast objects: Objects such as white walls or blue skies are low contrast objects. Passive auto focus systems rely on the fact that the focus quality significantly changes in relation to the optical components position. This is only true for high contrast objects.
