Macro Photography

By definition, macro photography is producing an image such that your object taken in your image sensor is 1:1. Anything less than that is termed as close up photography. There are many different types of accessories available in the market that enables you to do macro photography. While some of these accessories may not offer you the ability to do 1:1 image but they cost less than a dedicated macro len. You should consider getting them if you wish to try out macro photography.

Close up filter

Close up filters are some magnifying glasses which you can mount on the front element of the len. They came in different rating such as +1, +2, +4, +10 and can be bought cheaply. They can be stacked together to provide more magnification.

Extension tube
Extension tubes are mounted before the len so as to move the len further away from the film plane. This allows increased magnification and the higher the extension, the closer you will be able to focus. There is always a limit as to how much focusing you can get. This is because all lens have minimum focusing distance. If you use a wider angle, you probably would not be able to take a picture since the front len is closer to the object.

Reverse macro ring
Reverse macro ring is an adaptor that mounts the front element of lens in order to achieve close up ability. Reverse macro ring is another cheap alternative you can consider but you will risk exposing your rear end of your lens to unfavourable dust particles. There are couple of articles available on the Net that will teach people how to do-it-yourself.
