Writer and photography / James Tanguay Porphyrography is a long exposure dry plate process that uses a lensed camera and novel iron-based chemistry to make direct positive transparent images on glass plates. Porphyrography is often attractive to students because of its relatively simple technique and its use of inexpensive chemicals. Perhaps its most appealing aspect, however, is that it does not require a darkroom. The light-sensitive iron salt used in … Read more
Scott Wittenburg shares his experience of working with large format x-ray film photography and how he uses them as an inexpensive and fun way to create large-format negatives.

In this excerpt from “Jill Enfield’s Guide to Photographic Alternative Processes”, Jill shows us how to print Pyrofoto, Laser Transfers, Gum bichromates, Cyanotypes, Silkscreen PhotoEZ and Phototransfer onto different surfaces.
An X-ray is like a picture, except the fact that it uses the infamous x-rays instead of visible light. Another difference is that in photography we usually capture the light that is reflected by objects, while in x-ray capture the rays pass through the objects, more precisely our body. But if it were an analogue camera?
