    Thanks Bill

    I bought the book, I like books

    Looked up your prior posts

    I am impressed!

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...

    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.

    There are only three types of mounting flanges; too big, too small and wrong thread!

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

    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.
