i'm now quite done catching up on badly overdue darkroom projects, but as time permits me in the coming months i'll be attempting some ultra large format macro reversal images. i'll update here in the thread as progress is made.
I'm looking forward to reading them... I find this fascinating and hope to play with it myself eventually.
My search showed SCN in the FD or the SD or both. My opinion, after looking at a lot of data says it is best in the FD, but don't discount use in the SD.
hey PE, can you make any comment on what you think is going on in the solarization process, or point me toward some academic/scientific studies on the phenomenon? i'd like to do more than guess at precisely what it is that i was doing there.
for a progress update on the project to make a bigger camera for the purposes of this process, attempts to this point have been abortive. i shall endeavor to resolve this in the coming week.
so, small update. i built a pinhole camera to take fullsize photos and did some work yesterday with 11x14" paper. results were... not ideal. the long exposure times really hinder getting adequate feedback, and i was really panicked to get the work done on a schedule. this means that my poor results with the process were probably exacerbated, but at the best of times it can be a little unpredicatable (particularly when i'm relying on my hand to do reliable timing on the second exposure).
no time to post results, not that they are good anyway, but just wanted to mention that i was still working on it.
goddamn, is that panchromatic B&W paper? with an IDmax of 2.3 without toning? ffffff.... WHY ARE YOU USING GOOD PAPER FOR SCREWING AROUND??!!
also, i meter my paper at EI 25 and use a super high concentrated developer for my "controlled" solarization reversal.
