First film scans

I know many of you will have been waiting patiently to see what the V750 can do with film scans so we will jump straight in with this.

35mm scans

The mounted slide holder is the same as the V700, for a professional scanner this holder is far too flimsy. This holder is an improvement on their previous 35mm holders, now you can pre load the holder with up to 12 mounted slides. This means that you can start scanning straight away. With previous holders there was an aperture which you dropped your slides into, gNovember 7, 2006face. The new holder has sprung clips to keep the slides in place and loading the slides is very quick. I am slightly concerned with the quality of material used for the clips, it feels like brittle plastic although Epson may say it's a Poly this or that, I can imagine with heavy duty use these could easily snap off - so far none have. Given that the V750 is aimed at the professional user, Epson may have to re-think the durability of the holder - we will see.

The first scans

For our first scan I will be using the same harbour scene that was used in the V700 review and I will place the scans side by side. Please note that I have not applied any Digital ICE to the scans, I apologise for the dusty shots

The above scan at 3200dpi produced a 38mb file size and took 1min 09sec to complete. Although at first glance there doesn't seem to be a world of difference to the two scans, on closer inspection the V750 is showing more detail, this may be lost on the above scan due to JPEG compression.

At 4800dpi the scan from the V750 still appears to be sharper, but magnify this to 200 or 300% and we are starting to see some strange looking artifacts. The 4800dpi scan produced a 85mb file and took 1min 20sec.

The same section from a scan made with SilverFast - can there be a problem with EpsonScan?
An extra scan at 4800dpi using SilverFast - just to be sure

Just to be absolutely sure about the artifacts issue I scanned the same portion again with SilverFast and this time it has produced very similar results to those seen in the EpsonScan. I should stress that these are 300% magnifications of a 4800dpi file. At 300dpi this would produce a print size of 22 x14 inches.

I have just printed an A3 print of the harbour scene on an Epson R2400 and the detail above measures less than 1/4 of an inch, short of using a very high power magnifying glass you will not see any artifacts. The print shows excellent detail throughout. This scenario reminds me of my darkroom days. I would shoot and develop a 5x4 negative to a very high quality, but could never match that quality in a print, there would always be a slight problem - negative pop, deviation in focus etc. This scan is looking very good when printed and I would be more than happy to submit the file for usage to any magazine.

At 6400dpi the V750 produced a 152mb file in 2min 38sec. The V750 is now showing its superior optical performance over the V700, although we may be splitting hairs. At a recent meeting with the Epson engineers who put together the scanners, I asked about the 6400 dpi optical resolution, I thought they were being over optimistic with their claim. The reply was that the optical resolution is measured in combination with the software, so yes their claim could be substantiated. The bottom line is that the V750 does produce a crisper looking scan. I will do some in depth testing later to find the actual optical resolution.
