Jennifer Deegan is working on a project to build a focus stacking microscope that takes deep focus photographs of plants anywhere between about 2.5mm and 1cm tall. At the moment she is concentrating on gametophyte ferns and Utricularia gibba traps.
If anyone has any more plant subjects that are photographically interesting at this scale, she would be really pleased to hear from them. Email Jennifer at email@example.com
