Macro Photography
Using specialist lenses and focus rigs I can get amazing images that are well beyond the range of standard lenses or dioptors, up to a magnification  of 1mm left to right in frame.

Blood flow, Cell division, Sperm and Eggs, Crystal growth.
Live action images through the light microscope  up to a magnification of 1000X. If you need more I know a man with an Electron Microscope in his shed!
