    Re: LPL 4550XL + Heiland LED Explainer?

    Your data from post #12 and my experience with 4x5 sheet film in both glass and glassless LPL carriers in my 4500II. :)

    Re: LPL 4550XL + Heiland LED Explainer?

    A 16.4°F rise most definitely distorts a 4x5 negative in the LPL glassless carrier. Concomitant decrease in relative humidity of the emulsion makes this pronounced.

    Not with a glass carrier, which maintains negatives flat regardless of the fact that they're noticeably heated. With a glassless carrier, it most definitely does cause significantly more deviation...

    Re: LPL 4550XL + Heiland LED Explainer?

    Lack of heat and, therefore, the ability to use a glassless 4x5 carrier without flatness issues. This is a big advantage with films having very glossy emulsion sides, such as TMX and Acros, that can...

    Be sure to let him know the dimensional tolerances when sending that shutter. Distance between mounting surfaces is critical.

  16. Re: Happy New Year from Kodak via Michael Raso...Kodak Price Increase

  17. Re: Happy New Year from Kodak via Michael Raso...Kodak Price Increase

    Neither this particular retailer nor Eastman Kodak nor Kodak Alaris need justify the retail price of any film. 8x10 320TXP sells for what the market is willing to pay for it. Period.
