MJ> If you like more grain, use a condenser enlarger; if you like less grain, MJ> use a diffusion enlarger. Bear in mind that most enlarger light sources are MJ> neither fully diffuse nor collimated. The range from most diffuse to least MJ> looks something like this:
MJ> Cold light MJ> Dichroic-style (quartz bulb with mixing box, i.e., color enlargers, Leitz MJ> V35) MJ> Large frosted bulb with single condenser (i.e., most Dursts) MJ> Large frosted bulb with multiple condensers (Omega D series, etc.) MJ> True condensing (e.g., Leitz Focomat II) MJ> Point source enlargers MJ> --Mike Hi Mike, I have few WHATs and WHYs please... what's a "true condensing" enlarger, and how does it differ from an enlarger "Large frosted bulb with multiple condensers"? Why is a multiple condenser more point that single condenser? Point source enlargers... I have been toying with the idea of enlarging using a point source for extreme sharpness effect or grain effect. I have hundreds of meters of sound film which I can develop to an almost-normal contrast (similar to Technical Pan, although not panchromatic), which has none grain at all. I thought it would make a nice film for point source enlarging... Can you give me any pointers please on this technique? Thanks!
