I havent posted much in this forum... but do love reading it.
I find the work to be somewhat in argument with its presentation and subject matter. The muddy/funky/experimental method of printing seems to only try and exemplify the "disgusting" characteristic of the work. Almost (despite what her words and thoughts seem to be) as though she is trying to get the viewer to see it as revolting etc. I find that to conflict when I view it.
The method of creation (processes used, presentation method, etc) are an integral part of the overall reaction a viewer has, in my opinion. Something that comes to mind for me is work like Keriks wetplate photographs of flowers, or Robb Kendricks choice of wet plate for his texas cowboy projects, In the case of keriks work I find the somewhat dreamy method of printing to fit the delicate and almost transient beauty of the chosen subject to be expressed wonderfully with the method of wet plate. Similiarly Kendriks work with the modern day cowboys and his choice to use a process that requires "hard work" and a hands on approach to be fitting for the subject, a group of society that makes their living working with their hands and actually doing things on their own.
In these examples the method and processes used only assist in better presentation of the work. In Manchots work she seems to be try to exagerate the notion that the subject matter is supposed to be revolting or disgusting, when in fact growing older, gaining weight, and veering away from the societally excepted "beauty" is something to embrace and cherish, as many have pointed out already.
