Macro

 

Macro photography invented by Fritz Goro, is extreme close-up photography, usually of very small subjects, in which the size of the subject in the photograph is greater than life size (though macrophotography technically refers to the art of making very large photographs). By some definitions, a macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater. However in other uses it refers to a finished photograph of a subject at greater than life size.

 

Macro lenses of different focal lengths find 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
