Digital Camera Tips: Shooting Macro Pictures
(source: http://cameras.about.com/od/cameratips/a/macro.htm)

Here are some tips to get started:

* Like any other photo that you take, simplify.

* Fill the photo with your subject.

* Sharp focus is a must.

* Try shooting from different angles. If you’re looking for deep saturation of the colors, use front lighting. If you’d like to bring out the texture of your subject, side lighting is the way to go.

* due to the narrow depth of field, the background will usually be thrown completely out of focus, which allows the natural background to be nice backdrop,. Just make sure you don’t have anything distracting in the back that’s recognizable (branches, cigarette butts, etc.).
