Opposites attract – Salted paper and cyanotype curves

I was doing a quick classic cyanotype print to verify a paper (Schut Laurier) indeed works on this process. I knew it did as I’ve used it before in this capacity, but I just wanted to make sure before recommended it. This also create the opportunity to plot the response curve, and since I had a salted paper print on my desk as well, a comparison is easy enough to make!

Collimated vs. diffuse light – a cyanotype example

On a forum, someone asked how to get their cyanotypes made with 3D objects instead of a negative crisper. The fundamental issue at work here is how collimated or diffuse the light source is. Here’s a quick example of the difference between both.
