Mark, we had an intensive topic on this issue, I understand your point and I agreed in part (or disagreed in part), you are mostly right regarding developers with active solvents working on small negatives, f.e. Rodinal does not have active solvent and works fine for MF and LF negs diluted 1+25 (excellent contrast and good acutance), problem with small negs is grain, this issue is not so significant with larger negs: I uploaded to my blog an image twice larger than that one in Flickr, please click on thumbnail, you'll see the image quality does not change and scaling the original TIFF 16 bits grey document you are on a 11'x11' print: http://itarphotos.blogspot.com/2010/02/px-125microdol-x-full-strength.html and this is a 4786 x 1148 pixels PX 125/Microdol X full strength image, (Please see the original size) http://www.flickr.com/photos/itarfoto/4227455285/ BTW thanks for your interest; I appreciate your technical opinion.
