So if I am understanding correctly, essentially the print contrast is controlled by the type of light that paper is exposed to. Why then it does not matter what type of bulb is used for exposing Lodima/Lupex? Would a halogen bulb, vs LED vs fluorescent bulb not yield different levels of contrast?
I am probably making it too complicated but just in general, I am a bit confused that a filter can affect the contrast under an enlarger but the light type does not matter when exposing paper under a bare bulb.
