I used to teach photography in college and I have written 90 tutorials on different aspects of photography and composition. Do you have a place to put them? I don't see a resources folder. I would submit it as a photo with a caption (Photography tutorials) and if you scroll down there is a list of 90 different topics with links to the tutorials I wrote (most have examples).
I took a portrait with a 35 mm camera then made a 4x5 lithogram, using that as my final negative to create my print, would the image still be considered for this group as the original negative was 35 mm?
