My tutor sent a link to us all in the class containing youtube videos of experimental photography. Pinhole cameras,Cyanotypes (blueprints),dodging and burning, combination printing, sepia printing, split grade printing, making salt prints with digital negatives, colour prints, wet vs inkjet printing, gumoil printing and photograms all very interesting if you want to look on youtube. I am particularly interested in giving gumoil printing a try it looks very artistic one for the near future I reckon.
