  2. Sources for holographic stuff, for all those with
    7000 lp/mm lenses:

    Everybody seems to be selling the same film, though:

    And, if you mix your own, formulas for holography

    One view on TP, GB & TMX:

    [My results differed in that I found TP to be qualitatively
    and quantitatively better than TMX.]

    Google - the genius in everyone.

    Interesting. The author states "For very fine structures an
    even finer pattern can be used, again on a glass plate, with a
    chromium layer in which the patterns are etched."

    Is this a Ronchi Ruling ?

    IMO each film has it's merits. Dedicating oneself to using a
    singular emulsion for all usage is about like saying you will wear
    construction boots to run in the Boston Marathon.

    In general I agree with your comment about TMX v. TP though I
    have to point out that i pulled to EI32 and developed in D23, TMX is
    virtually indistinguishable.
