unlike the previous post, in that I am very familiar with Michael Kenna’s work, I am not familiar with Nancy Rexroth. thus, I cannot say what her style, if she has one, is like. however, I can glance at her work in the magnificent re-print of her book IOWA, and know that it is a plastic “toy” camera: in this case, a Diana. this is exemplified by the photo below, which I think it is exemplary of the use of a plastic camera. for example, the increased contrast in the center is nicely utilized to accentuate geometry/form, along with the lower contrast, vignetting, and blurring on the edges to include the subject of the photo.
