    So we already have the materials, if E6 does go, there is a way of producing slides from negatives.

For Europe that might mean something like 2006. For the US maybe something like 2003.

    If and when film sales go back to that level, Kodak (or whoever purchased the technology using it with whichever brand name) might easily think about producing Kodachrome again. In 2006 Kodachrome was still a viable product and it would be some sort of a "flagship" product for Kodak, a bit like Porsche continues to sell their 911-family cars: even though they are not the latest in technology, there still is a market for "retro" technology provided it is well realized. Values like "tradition" and "history" do have a meaning, and Kodachrome might be the 911 (or the Morgan) of the future slide market.

    The first condition to become true is that the market bounces back to where it was some 6 years ago. Not easy for sure, but not impossible either.
    I think it would be easier to modify an E6 emulsion to give a Kodachrome like colour response and grain then to start making true Kodachrome film again. Would probably still cost millions to produce the first roll though.

    The formulas were published decades ago in the Dignan Newsletter. At one time all the newletters were available on microfiche.

    IIRC, Ilfoflex makes slides from slides!

    And now back on topic...

    The current price of Kodachrome developing has been set. I went and bought all of the Kodak E100G and E100VS I could, and those few boxes are in my freezer. Yeah, I'm going to miss E6. The limited range allows me to accentuate things, while C41 gives me too much in the background.

    Ilfoflex from Ilford has an emulsion for processing in RA-4. In the standard neg/neg process it forms a positive. However it has an opaque white base.

    The material which seemingly is refered in a post above is Ilfoclear the one-pass version of this material and coated on transparent base.

    I stand corrected. I do know that there is a pos-pos version and that is what I was thinking of. I have forgotten its name.

    Sorry.

    ILFOFLEX is an Ra-4 print material its Ilfords product similar to Fujiflex it is not like duraclear, fuji clear, ilfoclear. slides can not be made from this or from the other metioned display materials. they are not designed for projecting. Agfa however does make products that work like kodak 4111 print film which is process c-41. The colour and contrast of Ilfoflex is amazing and the paper Ra-4 reverses wonderfully. I have found no material to reverse as well as ilfoflex. I should also note when printing ilfochromes for exhibitions if there are also images form colour negative the Ilfoflex was the best choice for continuity.

    As the issue of print film used as camera film has come up a few posts ago, I was asked to comment on it:


    Display films (and print films) in general have to 2 shortcomings concernig use as camera films:

    -) very slow speed

    -) their sensitization is optimised for the three dyes of the original film, not for the wide spectrum as in our environment


    Something similar comes true for negative camera films. They are not necessarily good slide films. (Aside of the mask and Dmax issues.)
    Here the problem may be that their dyes are to fit the sensitivity of the print material and vice-versa.


    In the whole reproduction line we got the colour scope of the object world at the beginning and the viewers eyes at the end. What happens inbetween may be a total different story.

    I have 8 rolls of some old Kodak SO-somethingorother that makes slides from color negatives. If you shoot it in a camera you get very blue results.

    You are to develop it with standard C-41 process.
