Recently I have been playing with creating the look of alternative photograph processing using Photoshop, (I dont have the time, equipment or money to invest in doing it properly).
I have been a huge fan of Vernon Trents work since a model I worked with a while back posted photos on Facebook of some of his Cyantype images.
his website is here: http://www.vernontrent.com (check out his alternative process gallery)
So playing in Photoshop I have come up with a few images that I am happy with, I have to say that the actual physical prints look so much better than what you are seeing on the screen here.
