Experimenting in my room with various cameras, angles, lighting techniques and developing times. Using a Rollei 35S, Zeiss Ikon nettar 510/2, Zenza Bronica SQ-A & B, Kodak 66 all shot using bulb and a manually fired flash gun. Putting the ISO 3 paper in the back on the cameras allowed for slower shutter speeds and a lot more latitude, meaning double, triple and even up to 6 exposures are possible while still retaining detail. Cutting the paper in the dark was very time consuming. The medium format negs have the most detail and the DOF is very deep wide open, because the paper is thicker than film and slower, the images appear deeper and you can see that there is layers in the paper and image, easier than cellulose. I developed each image for as long as I wanted, some for 1 minute and some for 4 minutes or so, then fixed for 5. Depending on the exposure and how strong the chemicals were diluted the times variated from every image. Experimenting with something I leaned at College as one of the first photographic exercises to do in the darkroom is always exciting and very challenging to just set up, but the results are always different and the final outcomes are quite amazing.
