I also recall an article in View Camera about using a frosted piece of acetate in register with the negative and using a pencil to shade areas to be dodged. When I get a chance I will find the issue and provide author and date of the issue.

I have not heard of Brett Weston using a "jiggle frame". Though it may very well be true. I have heard of a jiggle frame before and it was indicated as being effective by the person relating. Have you used it in your printing?
