Well, for one thing, as I read this first part of the book, it is amazing to me how much photography has been progressing and changing throughout the years. Going from the standard black and white photography, to color photography, shooting things around you to setting up a scene or narrative. Things change so much. In fact, they are always changing. You can't turn around without seeing something that is new or is the "new thing". One thing that I do love about the art world, is how it takes things that people use, for instance, the use of color, narrative photography, etc., and change it or add new things to it. I love that Eggleston and Shore revolutionized the art world by bringing in color photography and putting it in the gallery. Their photos are beautiful and worth taking a long hard look at. Which is one of the reasons that I am glad their work was put into galleries and museums so that we could contemplate them and study them and their different artistic qualities.
I also love the way that photographers go out and interact with the world as they do some of their projects. Take, for example, Tatsumi Orimoto, who "hid his face under a sculptural mass of bread and performed normal everyday activities". Going out into the world and doing these projects while photographing them, is a great way to do some experimental work. You get to see people's reactions, or get a point across, whatever may be your means for doing the project. Or just because you wanted to try something like that, I think it is a great idea and a wonderful concept. If I was a person who was in that community while Orimoto was doing his piece, I would be intrigued and it would give me ideas to possibly imitate that in some way.
That is one thing I love about photography, is experimenting with different ideas and different aspects of art and photography. It is also a good idea because you may find something you love to do, and continue using that in your work.
