Beauty! Did you do any smoothing on it?

Hello,

    While the moon is up and the snow and rain are down, I went digging through old negative sets... I am finding it almost impossible to match the original scans of the PPF 400 ... strange because I have better equipment and techniques... but it might lend credence to what I read in my trade journals many years ago... that PPF 400 fades. This was originally noticed by portrait photographers who were making reprints from portraits shot a year earlier... the customer returned the reprints saying they did not match the original images... turns out that no matter what they did, they could not match the original prints. IMHO this is why Kodak pulled PPF off the market.

    So.... I happened upon 3 negatives of M81 shot with an "A" grade C-14 on Fuji SHG 400 at f/7 from Mount Pinos back when it was a dark place... these worked quite well and I reprocessed them and added the image to my web site... I know it does not have the detail of a CCD, but it has field and it also shows this faint blue blob above it that must be some kind of companion like the Magellenic Clouds are to us... only one real background galaxy showed up... another film vs. CCD difference... I tried to be a bit restrained in my presentation of the image... have a habit of going a bit too far at times...
