    The agony of the cold light and the VC paper

    Well,

    everything I read said don't do it, but I had a window of opportunity last night and only VC paper. It was time to try out the new (to me) Omega E3 enlarger I got.

    Ah well, I probably picked the worst negative for this anyway, but in the end no filtration could save me. From what I read, the cold-lights put out too much blue to be used with VC paper.

    I read some people mentioning using a yellow filter to balance the color of the cold light. There is a filter drawer just below the cold light, so some sort of filtering must be possible.

    Thanks,

    Matt

    I do not know the cost or if it is available but Aristo offers bulbs that have a spectral response for VC papers that is superior to bulbs that 15 are more years old. What can it hurt to ask Aristo and to consider the expense.? The fact that you have a filter drawer will come in very handy. If you can get strong green lighting gel made by Roscoe and use that inconjunction with the coldlight bulb as split exposures you may find yourself very satisfied with the coldlight and VC paper. I would expect the Roscoe filter to be fairly inexpensive.

    Depending on many factors..........a CP20Y or CP40Y filter could put you in the ball park.

    Heya---

    thanks for the suggestions. I forgot about my late night reading about better color balanced lights. Unfortunately, the cold head on the E3 takes a set of 4 strait mini-tubes (like the ones in flourescent lanterns). I think the Aristo ones (at least the ones I can see on the B&H webstsite) are the serpentine type. However, they do seem to sell a warm (3000K) as opposed to the 4100K that seems more standard "cool white".

    Murray--the filters sound like a good idea. I'll see if I can find any at the San Jose PhotoFair this weekend. The ones I see online are 6x6, and the drawer takes 5x7. I can probably make something work.

    Thanks a lot!

    Matt

    Just to be sure, was the problem excessively heinous contrast?

    Murray--yes, that was the problem. No matter what filters I tried, I got really harsh contrast.

    OK, then the filter (probably the 40Y?) should help nudge things toward the soft end

    Might try looking for a studio gel. They come in some pretty big sizes.

    If you like to experiment try stacking more than one filter.

    I use a 40ccy in my enlarger. I have an ancient Beseler with a custom (for it's time) cold light head. The 40ccy in conjunction with MG VC filters works just fine with VC paper.
    Good luck.
