Epson V700 resolution tests - 645 film

2007-04-19 Thread Godfrey DiGiorgi
The other day I posted a Pentax 645 photo made with the 35mm lens, scanned with a new Epson V700 scanner: http://homepage.mac.com/ramarren/photo/PAW7/19b.htm One person mentioned that running it at 8x sampling would help improve resolution, another person mentioned that setting the negati

The res is definitely better at the 6400 dpi resolution. But the file sizes are getting big. My question is, are you pulling out the grain, as well? One of the things I've noticed when scanning black and white is that going full tilt boogie for resolution ends up giving me detail but with grain. T

Anxious to see the 35mm scan comparisons. Put them up against a 100 ISO K10D image having received one click of "Auto Sharpen". Jack --- Godfrey DiGiorgi <[EMAIL PROTECTED]> wrote: > The other day I posted a Pentax 645 photo made with the 35mm lens, > scanned with a new Epson V700 scanner: >

Thanks for all the comments. I've spent a bit of time running more scans and now I'm figuring out what's what for 35mm and subminiature formats, but I thought I'd respond to a couple of these notes. >>http://homepage.mac.com/ramarren/photo/PAW7/19b.htm >>http://homepage.mac.com/godder

I'm sorry, but I don't know what you're trying to see. The only reason to do this is to compare a film and scan vs a digital capture of the same subject. That's boring ... it's been done. Besides, I don't know what you use to do your DSLR image processing is, but I don't have anything that i

Well, it's been done to death, I know. The web will, also, give one about all they can stand. The reason it's been done and is being done is because of irrepressible curiosity about camera and process comparisons. I don't think I need to explain "what I'm trying to see" and I accept that your tests
