EPSON V700 Photo Scanner

More medium format tests

Before moving on to the 5x4 film scans I want to run a few more tests on the film height adjusters. I have just found the following information in the user guide.

If you are not satisfied with the quality of scanned film images after trying all the solutions above, you can adjust the height between the film holder and the document table. See the instructions below to increase or decrease the space between the film holder and document table. The default height between the film holder and document table is 3 mm (0.12 inch).

  • Remove and rotate the film height adjusters on the back of the film holder so that the arrow on the adjusters face the + symbol on the bottom of the film holder. This increases the height between the film holder and document table to 3.5 mm (0.14 inch).

 

  • Remove all of the film height adjusters on the back of the film holder to decrease the height between the film holder and the document table to 2.5 mm (0.1 inch).

 

  • To return the film holder to its default height, 3 mm (0.12 inch), place the film height adjusters so that the arrow on the adjusters face the O symbol on the bottom of the film holder.

I hope the above illustrations are clear enough, I am going to re-run the modern architecture scan at the other two heights.

Default adjuster settings - 3mm
No Adjusters fitted - 2.5mm
Adjusters set to 3.5mm

Setting the height adjusters to 3.5mm makes a big difference to the overall image quality, I am surprised at the sharpness gain by simply rotating the height adjusters, I just wish this information had been easier to find from the outset. I'm sure many users are going to look at their scans and wonder what advantage the V700 offers over the 4890 or 4990. Once they discover the height permutations they will be enlightened. All the above images are new scans just to keep the corrections consistent.

My worst nightmare has just hit me. After seeing how much improvement was made by adjusting the height on medium format film I decided to try the same on 35mm film. Need I go on? Yes, Vincent, this is an interactive review and you must remain loyal to the readers.

OK, I scanned the boat pictures from page 10 again and here are the results.

Scan as per page 10 - with USM applied 3200dpi
With the film adjusters rotated to the 3.5mm setting
Original page 10 4800dpi with USM
4800dpi With the film adjusters rotated to the 3.5mm setting
Original page 10 6400dpi scan with USM
6400dpi With the film adjusters rotated to the 3.5mm setting
Nikon 4000 scan 4000dpi
New Epson V700 scan at 3.5mm 4000dpi
Original Page 8 Epson V700 scan

 

It may not be very clear on these JPEG shots, but there is a marked difference in quality once the film height adjusters have been rotated. I am getting better results at 3.5mm, so I can only assume that the Epson technical engineers must have also had better results at this height, then why didn't they make this the default setting? I also repeated the Nikon 4000 test scan with the height adjusters set to 3.5mm and can now say that the Epson V700 has turned in a better sacn than the dedicated film scanner..

Users will save a lot of time and disappointment if the adjusters were factory fitted for optimum sharpness, failing that, easier to find information on this subject would be handy, it realy has made all the difference as you can see.

How about this for an idea - a printed manual!
