Macro Photography

Also known as photomacrography or macrography is extreme close up photography. Usually marco photography is taken of very small objects or smaller details of a larger object. This kind of photography makes the objects or subject become greater than life size and be able to be seen in greater detail.

‘The ratio of the subject size on the film plane (or sensor plane) to the actual subject size is known as the reproduction ratio. Likewise, a macro lens is classically a lens capable of reproduction ratios of at least 1:1, although it often refers to any lens with a large reproduction ratio, despite rarely exceeding 1:1.’  Reproduction ratios that are much greater than 1:1 are considered photomicrographt which is often achieved with a digital microscope.’

Most modern macro lenses can provide excellent optical quality for normal photography and as well as focus continuously to ‘inifinity’. Some true macro lenses can achieve higher magnification than life szie which allows photos of things like structures of the small insect eyes, snowflakes or other small objects.

Macro lenses of different focal lengths have different uses:

  • Continuously-variable focal length – suitable for virtually all macro subjects
  • 45–65 mm – product photography, small objects that can be approached closely without causing undesirable influence, and scenes requiring natural background perspective
  • 90–105 mm – insects, flowers, and small objects from a comfortable distance
  • 150–200 mm – insects and other small animals where additional working distance is required

Depth of field is important in macro photography, because of  limited depth of field when focusing on smaller objects or close up details. This means that a small aperture (higher f-stop) is normally required to achieve a good sharpness. This also either requires a slow shutter speed, good lighting, or a high ISO.

Examples:

This is a good example of macro photography the shallow depth of field, small subject with a high reproduction ratio.

An example using food as the subject, the shallow depth of field helps focus on specific details of the food while keeping the rest out of focus. I think this kind of food photography is particulary nice to look at.

Using marco photography you are able to achieve interesting images and compositions using unusual objects.
