I had taken a lot of time to search for threads about Espon V700 scanner but still have the following questions.
1. Sharpness of film scanning
This may be the most frequent question on V700. I want to scan 8x10, 4x5, 120 and 135 films that I shot in past 20 years. My purpose is to scan them at max possible resolution before they deteriorate in future. (consider the cost per scan, drum scanning is out of question at the moment.)
8x10 film
I put the film on scanner glass and then put a glass on the film to ensure flatness. Newton ring occurs. I know that an anti newton glass that I am going to buy one to solve this problem. I scan 8x10 film by 2400 dpi with espon software. The detail of the image is not sharp until I downsize the resolution to 800 dpi in Photoshop. Is it the max. resolution of V700 I can get? Then, I scan 120 film by the same operation. I get a file of 769MB from 6x9cm format with 6400dpi. The image at Photoshop is not sharp until I downsize to 1200 dpi but the file becomes 27MB.
My impression is : to scan films which is put on the scanner glass could not yield sharp image above 800 or 1200 dpi.
4x5 film
If I put 4x5 film directly on the scanner glass, may I get sharp image at only 1200 or lower dpi? I use espon film holder and scan at 2400 dpi and then downsize to 1600 or 1200 dpi. The image is sharper. People said that a third party film holder with adjustable height could improve the sharpness. I don't know to what extent it is sharper.
120 and 135 film
Someone suggest to put ANR glass on 120 and 135 film holders to ensure film flatness. How far could it improve sharpness if the scanner focus is not there? The 120 and 135 film holders from espon is not adjustable in height. Should I need to use third party film holder to adjust the heights?
2. Noise
When I scan some old films with V700, there exists noise in the files. I mean films shot over 20 years ago. Had tried to use Photoshop and other noise reduction softwares but the result is far from my satisfaction. I came across the idea of scanning film by DSLR camera by using macro lens so that noise became less apparent because of macro focusing. To me, noise problem is equally important. Do you have any advice?
Thanks a lot.
