    One and three fourths years later (more or less), I am updating this. I have not forgotten you all.

    The book is in revision VI, with about 250 pages and 120 figures and photos. It is fully copyright, and I will be registering it with the Library of Congress soon. The cover is designed and the figures are all numbered and in order. Some don't look too good yet and will have to be redrawn. I have 2 companies locally that can duplicate the DVDs.

    I need an editor to read over and correct style in the book and I have at least 3 friends here ready and willing to read it through to check it out.

    So, I have not forgotten you all. I had to take some time due to family health issues and the fact that the book is harder than expected!

    Version V is here on the table, and version VI is on disk ready to print out. I will print several copies for the editors and go from there.

    Just to show progress.........

    So is VI the version that will be for sale, once proof-read and passed?

    Athiril;

    After my 3 or 4 editors finish, and I make corrections, it will probably be called VII.

    BTW, the core of the book is about 58M.

    I have it in 4 files and the total is a bit larger.

    Hi PE,
    I can't wait ! But I will. Will this book be available as E-Book, an old-fashioned printed book, or both?
    I don't usually value autographs. But in this case I might.

    Thanks for your efforts! And do keep a backup (or two) just in case something happens ...

    Ron gave me the honour of leafing through his manuscript last week when I visited him in Rochester, and the book looks good. Ron's making sure to give lots of information to help us find our errors in the process, because we will make errors.

    Thanks again, Ron, for taking the time to meet me - it was a pleasure. And all - if you can, go to George Eastman House in Rochester sometime, and research about it in advance because the possibilities there are amazing.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    Jim;

    Thanks for your kind comments. I am trying to do a good job, not a fast one.

    Bill;

    The book will probably be only in printed form similar to Bob Shanebrook's book.

    Ron,
    Where is the chapter on "Emulsions For Vegetarians." I mean, emulsions that do not contribute to the mistreatment and slaughter of cattle and hogs?

    Bill;

    I have a few patents and RDs on that subject. We used a copolymer with sulfur and nitrogen in it for pptn and a terpolymer for coating which had a crosslinking site. For color, we used a coupler grafted onto the terpolymer.

    Unfortunately, these things are hard to get and expensive. But, I do consider this seriously. OTOH, with all of the byproducts of cattle out there, why not make sure that they are not left to go to waste, but rather are used in a good cause.

    So, there is my position on this! I'll leave veggie emulsions for you!
