    Re: 4x5 Exposed Film Archiving

    I store all of my 4X5 and 5X7 negatives the same way, in Print File sheets, ordinary three-ring notebook. I have many stored that way since the 1980s and they are all still in pristine condition. I...
  2. Re: Likely Very Naive Question, sheet film then scan to produce a digital print.

  3. Re: Should I Drum Scan, X1 Flextight Scan, or use the Epson V850 w/Aztek Wet Mount Ki

    Hi Alan,

    Thank you for your comments about the tones. The tones are really very rich, but not by my design. This negative was made in my first years of using LF in the early 1980s, and I...
  4. Re: Should I Drum Scan, X1 Flextight Scan, or use the Epson V850 w/Aztek Wet Mount Ki

    Yes, in principle I would like to get all of the detail out of a scan, as scanning negatives is very time consuming.

    I have found that with 5X7 I am not able to get quite as much information as I...
  5. Re: Scanning 4x5: Buying an Epson Flatbed VS my current DSLR (5DII) VS Lab Scans

    Sure, I plan to make physical prints with the files. 25 lpm at 11" wide would give image resolution of approximately 1200 ppi, or at 22" on the long dimension of about 600 ppi. I use a RIP (QTR) that...

  7. Re: Scanning 4x5: Buying an Epson Flatbed VS my current DSLR (5DII) VS Lab Scans

    I am using a Kaiser light panel with the Sony a7r iv, scanning in 16 shot pixel shift mode. Just completed a project of digitizing some 90-100 5X7 Tr-X negatives I made in 1994 in a two week stay in...
  8. Re: Should I Drum Scan, X1 Flextight Scan, or use the Epson V850 w/Aztek Wet Mount Ki

    Use of a pixel shift workflow looks promising for digitizing film of all size, as well as photographing anything not in motion.

    However, to take advantage of of this very high resolution...
  9. Re: Should I Drum Scan, X1 Flextight Scan, or use the Epson V850 w/Aztek Wet Mount Ki

    Re: DPL users/owners of Howtek/Aztek scanners

    Dean,

    With the 4500 you should be able to scan a 4X5 color negative or transparency at 4000 spi. File size would be slightly less than 2G, assuming RGB and 16 bit, much less if gray scale.
