The big Imago camera and it's current owner Susanna Kraus are behind this project. She convinced Ilford to give this a try.

I had a chance to try the paper a couple of months ago, and it does exactly what it says on the tin. It's relatively hard (grade 3-4) without pre-exposure, but a Zone III pre-exposure gets it into a normal range. Ilford recommends a darkroom pre-exposure, but I think an in-camera pre-exposure is simpler and does the same thing. It's not a bad idea for a pinhole project, but I would prefer to it the Fox Talbot way and make paper negatives with Ilford MGIV-RC with a yellow filter.
