    Re: Wet/dry plate holders for 4x5

    Why? Well printed plastic is just as durable as a fidelity holder. Possibly more so.

    Re: Ball or Pan-tilt head for 8x10?

    The thing with ball heads is that the vast majority of them are mildly terrible, in that they're either "locked" or "free", with very little in between.

  7. Re: Epson V850 Perfection ,Will it scan 8x10 Film ?

    Please define "not as good"-- it's a terribly vague term. There's a lot of FUD and misunderstanding about the Epson scanners, and vague terms don't help.

  8. Re: Epson V850 Perfection ,Will it scan 8x10 Film ?

    Even the "low-res" lens should hit 2400 PPI, so printing at 300 DPI, you get 8x enlargement. 600 DPI, 4x enlargement.

  11. Re: Banding problems with digital copy camera and fluorescent light source

    Well, yes-- any light source using direct AC is going to flicker. Get a decent DC power supply, and run the LED's from that.

    Or just get a decent LED lightbox.
