This is my cyanotype I made for Round 12 of the Postcard Exchange. The original image was taken on Scala 200X. I then used a Daylab to make a 4x5 negative using Polaroid Type 55. Then made a LOT of these images using the Photographer's Formulary old cyanotype kit and Stonhenge paper.
The image itself is of a columned gate somewhere in London, UK. I took it many years ago using one of my trusty Nikon F4e cameras and a 28-70mm zoom.
