"My best work is more analogous to architecture and sculpture than to painting. I made a posterior view, in flat, but very brilliant light, which outlines the figure with such a definite black line, that even photographers swear I have pencilled the negative,--I have used this light before on the dancing nudes."
Also, in the daybooks, Weston mentioned that he never uses artificial light...only natural light.
I believe this outline can also be seen lightly in the Charis nudes in the dunes.
As a side point...I have the Knees print in (at least) two books and noticed that they each are a different crop and contrast. I guess book prints always have to be taken with a grain of salt.
I vaguely remember reading more on this outline effect but know not where.
Hope this helps,
Thanks for that Gim, or should that be Jim. Now can someone explain that in the form of a lighting diagram?
