Macro photography is usually defined as extremely close up photography of very small subjects, in which the size of the subject in the photograph is greater than life size.
It can require specialised lenses which can focus close up to the object being photographed. A number of issues arise. Lighting is critical. Camera shake at slow speed becomes problematic but the most difficult aspect is depth of field and keeping the whole object in sharp focus. In our work shop we experienced all of these and discussed way of solving them.
