Hey- so I have a fairly modified DeVere 504 I've been using for years. Originally it was a Dichro model but I gutted the head to put in a cold light (it's a nice aristo unit- though a BIT small for complete coverage - I think it's the V54 mk.2 or something - it's a later model).
SINCE the coverage is a tiny bit problematic (should be fixed by using a fixture for the light in the correct position) I've been trying to figure out a way to get even more coverage out of it. I have a diffusion panel sitting DIRECTLY over the negative inside the bottom of the diffusion chamber. BUT - I'm ALSO trying to start printing 6x17 negatives. I milled out a 6x9 carrier to approximately 6x13 and that seems to work great so far.... but I want to take the head apart and mill out other obstructions so I can hit at LEAST 6x16 or so (really pushing the limits but I think it can be done)
At any rate - here's the problem:
CAN I move the light source UPWARDS an inch or so and get BETTER coverage? It's a bit of a mind game trying to think things through. From the perspective of illumination ONTO the diffusion panel you would think that higher is better. But If you think of it from the negative stage - the further away the source IS, the smaller it appears. Perhaps the right quality of diffusion panel would obviate that - however I was hoping someone here might have futzed around with this issue before (?).
Thanks
