    Re: Fomabrom Variant 111

    They had been trying some changes with the supercoating from what I recall.

    I think the OP should check to be sure that he's not been sent one of the fixed grade Fomabrom papers by accident. Or...

    The newest Epson inks are supposed to be better - but all inkjet inks are going to change with time, no matter what their partisans wish. The supposed testing is questionable to say the least - and...

    Re: Switch from Epson to Canon printer?

    That's essentially the main vote in favour of Epson - and they don't use the sub-tanks Canon use (to support hot swapping ink tanks) so they're easier to drain & mess with inks etc.

    Re: Preferences for 150-165mm lenses in 8x10?

    Out of the usual suspects (Super Angulon 165/8, Nikkor 150/8, Grandagon 155/6.8 etc) and any other more unusual lenses in that range, what do you like best for colour work in 8x10 - with potential...

  16. Re: Scanning 8x10 method Epson v850 super resolution lens

  17. Re: Scanning 8x10 method Epson v850 super resolution lens

    The Epson scan system delivers in the 2200-2400ppi range under extremely high contrast test conditions. However that is pretty irrelevant when the MTF drops under 50% below 700ppi and drops under 10%...
