Here is a small video which talks about Macro Photography and what all should be main consideration while shotting macro objects.
As we know MCRO/micro photography is about shooting very small objects. With normal lenses its very difficult because the are restricted from shooting objects from shorter distances which is main requirement of MACROs. Photographer needs a Macro lens or Extension Tubes for this purpose. Extension tubes are cheaper options which helps us using our standard lenses for shooting macro objects.
Even when we have Macro lenses and Extension tubes, there is challenge of getting nice Depth of field so that complete object is clear in final photograph. For that we need to shoot at low aperture which effectively means HIGH F value. Many lenses support F45 types for Macro shots. Since light will be low at F45, we need to shoot with slow shutter speed and TRIPOD would be must in that case.
