Hello everyone,
So, I've decided to try using direct positive paper (and maybe later, if I feel comfortable enough and crazy enough, dry or wet plates). I understand that exposing such medium is a bit tricky because it mostly reacts to UV and blue light, and therefore a lightmeter is of little use (unless you do a test plate and check the EI to reuse that). I've seen plenty of videos where people just blast super powerful strobes in people's faces and blind them for an hour, but I'm not really interested in doing that. So I was wondering : isn't it possible to use UV lights instead and figure out a correct, reliable and easily "replicable" exposure for portraits, indoors or outdoors ? There are small, portable units or even bulbs that do UV light. Can't they be used and set up at a certain distance in order to obtain a "fixed" exposure that you can easily reuse anywhere ? Wouldn't that be simpler and more effective than powerful strobes ? And if so, why I have never seen anyone using that ?
Also, I was wondering : can you place a blue filter, like a 47B, or a dark blue filter on top of your lightmeter to cut out the red light and obtain a decent reading for orthochromatic emulsions ? I have never seen anyone doing that either, so I'm wondering if it's doable or not.
Thank you beforehand for your answers !
Sincerely,
Yael.
