I experimented with a number of different chromatography processes to learn which method would be conceptually and aesthetically strongest for my own practice. Two of the failed tests I did were interesting enough in their own right that I kept them, too, though as is evident they use a different technique that proved less effective at pigment differentiation than the process I used for the main Transmigration Landscapes.
These are, respectively, Failed Test 1 and Failed Test 3.
