stickser Hi. I’d like to try and see what happens when you expose one black-and-white film onto another black-and-white film. That should produce a positive, but on black-and-white film. Has anyone ever done this before and can give me some tips, particularly regarding the exposure time? I’m not really sure how to judge it, and that would probably save me from wasting a few rolls of film. Many thanks and best regards!
MichaelLaun Hello stickser, Sure, that works. Either place the negative strip (in complete darkness) directly onto a black-and-white film, weigh it down with a glass plate to keep it flat, and expose it (using ambient light, under an enlarger, or with a flash – you’ll need to determine the exposure time by trial and error). Or clamp the negative into a slide copier attachment and photograph it. Both methods produce a 1:1 positive from the negative. Best regards, Michael
CPD Hi, You could have a look in the catalogue! On page 9, you’ll find ADOX Display Film. You can use it for enlargements and contact prints. The film is orthochromatic, so you can work under red darkroom lighting. Bye!
oliver_dresden ...in principle, this is a great way to make black-and-white slides, and they look really fantastic when projected. It’s worth using orthochromatic film, as the darkroom can, after all, be dimly lit with a red light. Exposure time between 1 and 2 seconds, development in Dokumol 1+5 for 4 minutes. You can use a Leitz ELDIA as an aid; you can get one second-hand for around 20 euros. But: the glass plate used to press the negative and film together has to be so perfectly clean, it’s enough to drive you mad... Regards, Oliver
