Using Gimp to predict how your single or multi layer process will look!

This is a video on how I am using Gimp to predict the outcome of my multi layered cyanotype projects but could be used for other processes as well. Here is a link to Gimp https://www.gimp.org/ Here is a link to my video on how to set it up for this process https://youtu.be/hVYB7RFjMwA Here is a link for the book Cyanotype Toning by Annette Golaz, which holds the key to a good magenta toned cyanotype layer https://a.co/d/a5Cv97c And here is a link to the duotone process for the yellow/cyan system https://www.alternativephotography.com/multi-coloured-cyanotype-print/
