Re: Sam Wang light?

Katharine,

What I wrote was that Sam uses a very dilute dichromate solution in
his work and his exposure times are still quite short. I know this
because I have watched him work. Sam's work clearly proves that gum
prints can be made with fairly short exposure times using other than
saturated dichromate solutions. Exactly what it is that you find
about this contrary to any other position I may have taken to "data"
is a mystery to me.

Indeed, I have no idea what kind of data you believe should be
forthcoming from either Sam or me. Sam describes his working
procedures rather completely in the article at UnblinkingEye. I am
not currently working with gum dichromate prints and have no
intention of providing data of any kind on the subject.
