This invention relates to photography and par
ticularly to a photographic out?t which will en
able relatively unskilled operators to make photo
graphs of objects at ?xed magni?cation under
?xed lighting conditions. One object of our in
vention is to provide an apparatus which can be
readily supported by an operator to take pictures
