To create a macro shot, first a camera which is capable of taking close up object is needed.

The basic requirement for camera for macro shot :
1. Macro lens.
2. Photo sensitivity of ISO 100 or ISO 80
3. Timer
4. Tripod

From my understanding, the less sensitive or lower ISO, the easier to produce detailed shots. Unfortunately, less sensitive, longer exposure time needed. Hence, macro shots is not suitable for casual photo graphing a.k.a. a tripod is needed. Else ghostly images will be produced. Timer is needed to avoid shaking the camera during the shot that may cause ghostly images.
