    That makes sense, regarding positives.

    I'm not sure I understand the part about blue filter - do you mean for contact printing on MG paper?

    Some talk of the tint itself acting as a filter during exposure. I think in thread 49xyz, hike!, this is unclearly proposed.

    Maybe I am blue sky drifting...

    An interesting proposal! Wouldn't that only influence the rear emulsion, after the light passes through the base? Actually now that I think about it isn't the x-ray film kind of lavender colored before fixing? Either way it would seem like you could test this by shooting two sheets back-to-back of a blue sky exposed to middle grey and then develop the same, and strip one side each (you'd have to keep track that you strip opposite sides). If the color causes a difference in exposure you'd see a difference in the density, no?

    Yes, but i'm not that crazy. Yet...

    I will live with the blueness.

    I do want hearof any X-Ray that is different, but I am happy with Kodak CSG and Ektascan

    Ektascan is single sided. The blue tint is after the light goes through the emulsion.
    I had in mind reversal processing and fast UV/blue exposure for cyanotype.
