I buy a roll of East European FOMABROM VARIANT III, with look to have special safelight specifications are :
I have the options to add special filters in the Thomas Duplex, I ask specific question in this topic: (there was a url link here which no longer exists)
or use LED red from SuperBrightLeds witch look to have good reputation among the darkroom users.
I will like to have some opinions from the users of this paper. What do you use as safelight?
Thanks a lot for the help.
FOMABROM VARIANT III is orthochromatic sensibilized photo paper so if you work
with it you should use safety illumination different from common black and white
photo paper. It is routinely processed at indirect safety illumination with wavelength
of 625 nm and higher, corresponding colour of safety illumination is orange or red.
As to its high sensitivity the processed material has to be exposed to such
illumination only for the time necessary for its processing. Length of exposure and a
distance of the processed material from the illumination source should be tested.
