Macro Q1: Is there a difference between macro and micro photography?
Strictly speaking, yes. Camera and lens manufacturers tend to bandy the term “macro” about rather freely. Often these lenses should really be classified as “close-focus” rather than macro. The magnification is typically described by a ratio – x:y. This refers to the ratio of real size of the object relative to its image size at the film plane – or digital CCD/CMOS sensor nowadays. Close-up photography can be anything up to about 1:3. Macrography is generally regarded as being imaging within the range 1:3 – 1:1 Micrography is generally regarded as being imaging within the range 2:1 – 5:1 Microscopy is anything beyond 5:1.
