A practical way for defining macro photography is by the strength of the lens, or how nearby it can focus. For true macro photography, you’ll want to have a lens that focuses down to a 1:1 range. For example,for 35mm film,your camera has to have the ability to focus on an area at least as small as 24×36mm ,because this is the size of the image on the film.After having the film developed,the picture of the subject on the negative or slide will be exactly the same size as the subject photographed.
What makes macro photography seductive is the level of detail that you see, sometimes for the first time – familiar objects become unusual and abstract and unusual objects become even more interesting.
There are many applications for macro photography: flowers,plants,butterflies, minerals,snowflakes… Your own backyard, a local garden,beach or forest can provide you with hours of fun with macro photography.
Of course macro photography isn’t always centred on the natural world. Collectors use macro photography to record coins,stamps and other collectibles that are very small.Some people use macro photography for documenting their possessions for insurance purposes or to illustrate their auction listings online.
Working with macro photography can be a whole new visual event for even the most advanced photographers.Every day can yield another subject and an endless supply of captivating images.The possibilities of macro photography are limited only by your imagination.
If you are interested in macro photography, then by all means consider purchasing a dedicated macro lens.SLR digital cameras with interchangeable lenses are ideal for macro photography.If you’re primarily interested in outdoor photography, consider a 180mm or 200mm macro lens.
Alternatively you can use extension tubes,reversing rings, or close-up diopter lens.
An extension tube is placed between the camera body and the lens. There is no glass in the tube – its purpose is to move the lens farther from the film (or digital sensor) so that magnification can be bigger.
Reversing ring is attached on the front of a lens and makes it possible to attach the lens in reverse.
Close-up diopter lens are placed in front of the camera’s main lens. These screw-in or slip-on attachments provide close focusing at very low cost.However,the quality of the pictures is variable.
