    Arcane? I thought that was all of us.

    Ron, Is not mixing emulsions on a bench, like some of us are doing, "arcane"?
    I thought that keeping alive these "arcane" practices is the whole point of your Wokshops,The Light Farm. and this very Forum. If not, lets all just purchace digital camers, the latest Photoshop and "To Hell with It"!
    Just for the record: I for one have never said that I had any knowledge of Emulsion making, other than what I learned from you and a few others. All I said is that I was "practiced" and "Pracice" includes a bunch of failed attempts.
    Joy anf Cheerio to All,

    About watery eyes??

    or the finish program that didn't.?

    Well it is true about the sun outside.
    But I live in a dark room. For me the safelight never sets.

    Whoa, there now Wildbill,

    I feel a might responsable for this, uh confusion.
    I could be always be wrong, but I surely think PE had other people in mind when he wrote that. Without a doubt!

    Although it is not my place to say so, please don't take it personally, as it definately was not directed at you.

    While PE did use the term arcane, he is just commenting on the fact that this method began a long time ago and things have become more automated.

    I don't like it when someone "ages" my emulsions by saying the technology is decades old, and arcane does seem rather servere, but no one had you in mind when those sentences were downed.

    Best Wishes

    Bill - I'm curious about how you were going to test the spectral senstivity of your emulsion. What kind of test are you going to do?

    Also, when you get this to work, you need to get a peristaltic pump so you can do some double runs and make a T-grain film. :^)

    Hi Kirk,
    I might consider selling a few dozen mg of the spectral dyes to you,as you are a fellow insect fan. As of yet, I have not opened the vials they came in. They are tucked in a dark corner of a freezer.
    As for testing the spectral sensitivity of my future emulsions, I intend to place a Kodak color chart transparency over the emulsion,which has been coated on glass, and expose with pops of a strobe. Thats as close to white light as I can get, ouside of going outside.
    As fof your T-grain emulsions, I thought that was your baby! I am waiting for your initiative.

    Ray,
    Thanks. Mabe I'm just overly sensative. I am painfuly aware that my carcase cannot keep up with my ambitions.
    Let us forget it,

    (Bill, just between you and me, I think Ron was actually talking about me!)

    My comments were meant for no one here on this thread at all. Sorry for the misunderstanding. I apologize for any confusion.

    As for testing Bill, I suggest using a WR 98, 99 and 70 (or equivalent narrow cutting filter set) over a step chart and exposing. An in-camera exposure is difficult to read, but a 3 color filter set with and without dye will give you the exact speed change in each region affected in terms of Log E (stops) speed change.

    I've tried the method you describe, Bill, and it is just not clear cut enough. However, if you wish to send me a sample, I'll expose it with my spectrosensitometer.

    Thanks Ron,
    I will follow your suggestion concerning exposing through WR filters. Sound a bit easier anyway.

    Bill - you should take Ron up on the spectrosensitizer. I've seen test prints from it and it is really cool and gives results just like you seen in the graphs in books and such.
