I found this reading on negatives to be very interesting in it’s explanation of the photogram. Christopher talks about how the photogram has a reduced ability when it comes to being able to produce a wide range of densities from the negative. As where with cyanotype or platinum there is a higher range of densities that are able to be taken from the negative. He also goes on to talk about Acrylic lift transparencies from printed sources, which reminded me of our hand sanitizer transfers we did in class. With this transfer technique we found that not over applying the hand sanitizer was the trick to avoiding the white spots on the final image.
