Even in the darkroom, there are endless ways to tinker with your negs and get very interesting images, like scratching, playing around with your chemicals to get weird tones, adding different solutions (ex: bleach bypass), and lots of different filters while enlarging. There is nothing wrong with pushing a media to it's limits, you just need to decide when it is necessary, and if it is contributing to your image in a meaningful way. To some people it may seem like Adam is just creating and displaying these images "because he can", without any kind of economy or decision making process, which is kind of boring. I think it's awesome simply because I'm new to the media, just like how pretty much everyone was blown away by the first movie projection of a horse running or whatever.
