Compare Wet Plate to Best LF Film

Thanks Bill

I bought the book, I like books

Looked up your prior posts

I am impressed!

I appreciate the gesture, but I already have the book. It was the specific paper by Mollenstedt and Spiedel that I couldn't find. The book is excellent and I highly recommend it, but if it just the resolution of collodion that concerns you I can scan the relevant pages and send them to you (or anyone else interested). The majority of the book covers silver gelatin emulsions and the technique of microphotography - there are only a couple pages about collodion.

Thanks for the compliment.

I am sure you will enjoy the book. It contains an enormous amount of information without being inaccessible. It is my favorite book among my collection.

Per the Kodak quote in Randy's post #16, perhaps the key words are "an extensive research program that these products cannot support". EK was desperate for cash in those days and were busy dismantling the Research Labs- and any product that wasn't showing a profit was about to be discontinued, if it wasn't already gone. And I suppose the astronomers had mostly gone digital by then.
Back on-topic, it's interesting to find out the resolution capability of wet-plate collodion, even if it's a quality that photographers are unlikely to be able to fully utilize. That said, I suppose that soon, someone will be enlarging a wet-plate neg to billboard size and getting up close to the print with an 8x loupe...

I just burned my last shekel on that project

A while back, I explored the availability of dry plates used in computer chip masking. The resolution was incredible (don't remember the specs now) but the cost was prohibitive.

New chips are in the range of 7nm (0.007 uM), so that's substantially finer than the really nice data in this thread.

This was back in 2009-2010, so chip technology was stikll not thaty tight . . .

Just got the book, it came out of NASA Headquarters Library Washington DC Printed Great Britain

VGC clean copy, maybe unread

Thank you

Yes, I don't think the book was often bought by individuals. My copy was originally held in the Library of Congress, before going to a U.S. army library, and then to me.
