Another useful tip from an online forum – to reduce the contrast of a photo paper negative, the advice is to “pre-flash” it with a short exposure to an enlarger light. I don’t have an enlarger so have rigged a small desk light with a couple of sheets of tracing paper over the shade and then added a filter holder and for the flashing added a number 9 Ilford magenta filter. Pre-Flashing the paper for 0.5 to 1.0 s seems to have given an improvement in tonality for the images. To test the process, I deliberately chose a high contrast picture – dark soil and white, sun-lit, crocus flower.
First – without flashing
With 5×7 sheet film being expensive, at over £1 a sheet, I have been looking for alternatives. I love the look paper negatives give to some images and so will continue to use paper as “film” for some subjects – particularly those that don’t move …
In searching discussion forums on alternative photographic processes, I came across questions and advice about using x-ray film. Working out at around 10p a sheet this looked almost too good to be true – but it works … and it looks great!
The film is described as being “sensitive to green light” so I wondered if, like photopaper it would render reds as black, but that is not the case. There is quite a good tonal range as the print below shows.
