Diffusion lens for Printing

I have a Omega b22 and would like a better diffussion look when printing my portraits. What are your favorites? Stockings? Clear plastic? What on the market these days. Thanks!

Others may differ, but I've never had good luck trying to diffuse when printing. The problem is that the light scatters the wrong way, ie; I think the shadows muck up the highlights. When you diffuse on the original shot, the highlights diffuse into the shadows, a very different effect. I'm somewhat hazy (pun intended) on this, so what's everybody think?

It can work with some prints, though it is definitely not the same effect as diffusing during shooting. When I started printing some 20 years ago, I used a patch of a nylon stocking. It seemed to work well and was not too expensive. ;-)

You can sometimes use the effect to reduce the graininess of a print by exposing it through the diffuser for 1/3 of the total time. Some sharpness is also lost, but sometimes the overall effect is just more pleasing.

I was admiring a friend's soft nudes recently and asked him how he got the effect. He says he prints part of the exposure through onion- skin paper (tracing paper). I tried it and it works beautifully.

Ed, is the onion skin in contact with the paper or under the lens? Alan Ross' technique has fot me wondering.

I got a diffused effect when I exposed a sheet of kentmere vc with the emusion side underneath, it worked well with nude photos. ( extend exposure time)

After trying everything under the sun to get the diffuse effect - spreading of the blacks - the problem is usually that the print contrast goes to pot - everything turns muddy -- of course as mentioned earlier, it does not work on all images. I have tried stockings, plastics, tissue paper etc. and have usually found they work *OK* with half exposure with and half without. I finally found the perfect solution that is repeatable. I bought a Tiffen (yes) ProMist filter - used on camera lens, it keeps the images pretty sharp, but spreads the highlights -- 0n the enlarger (under the lens the *entire* print exposure time) it spreads the blacks perfectly. Its pretty cheap ($25) and cinematographers seem to love it.
