Great job. Instructive, easily understandable, good illustrations... I
really like your introduction.
Just two minor flaws:
1.) There's a doubling of the following sentence on the initial page:
"Infrared photography is available in two forms, black and white
negative film and colour transparency
film, my prefered films are Kodak’s HIE for black and white and EIR for
colour. Both films have their
own merits, they can also give varying results depending on filtration."
2.) I'm not sure if the spectral transmission data for the Wratten #88A
on page 2 are correct. According to your graph, its cu-off frequency is
around 745 nm. If i remember right, the cut-off point lies rather around
715-720 nm.
Cheers, Eckahrd
