Competition September

Set Subject: Small world / Macro

Images Due: Monday 11 September

Competition Night: Monday 25 September

Magnification - or more precisely, the magnification ratio - is simply the relationship between of the size of the (in-focus) subject's projection on the imaging sensor and the subject's size in reality. If these are equal (1:1) then the size of the subject in the photograph is the same as the subject’s life-size, and is regarded as ‘true’ macro. Commonly however, ‘macro’ is considered to be a close-up photograph where the size of the subject on the sensor may be, for example, half (1:2) or a quarter (1:4) the subject’s life-size. So, for this competition, any close-up photograph of a subject is acceptable, with the lower magnification limit (e.g. 1:4, 1:8 etc.) left to the discretion of the photographer. For magnification ratio’s much higher than 1:1, for example 20:1 or higher, photographers usually attach a camera to a light microscope and this is referred to as ‘small world’ photography (e.g. Such photographs would also be acceptable in this competition. Subjects could be biological specimens or parts of them, for example insects, other animals or plants. The subject could also be a non-biological object or a part of it.
