Inspired by Renger-Patszch and The Bauhaus by Harry Callahan and Aaron Siskind, Peterson explored with the images that exploited a heavy contrast between just black and white- no greys. He created this technique using both camera and flat bed scanners in order to get the desired effect.
EXPERIMENTS
I had firstly picked out several images which I'd previously taken, and thought would end up having quite a strong and rounded contrast when applying the threshold. Secondly, I handled the images via Photoshop to avoid tampering with the original image. I had duplicated the image and then seleted 'Image' followed by 'Adjustments' and finally 'Threshold', where I was able to manage the level of threshold using a slider. I think there was definitely a difficulty knowing when to stop playing around with the threshold, as you could have too much black or too much white.. It was hard in some images to get the right balance, but I had asked peers who would help me decide. I was generally really pleased with the outcome of the images due to the abstract interpretation they had compared with the original images. Most of the images I had chosen to manage were finely detailed, are were most of Held-Peterson's. I think for my next book I may choose images with little or no detail to see how these would look, too.
