replacing Epson V750 glass & grains on the film

[yuexiachou29]

You can try wet-mounting with Kami fluid, directly on the glass; it will take care of some grain issues and scratches, too.
Also check your settings, film speed, development, etc to make sure the grain is actually coming from the scanner, not your film.

Hi Ari,

Ive always wanted to try wet mounting, what would you say the pros & cons on wet-mounting vs. using film holder?

cons: wet mounting directly against the glass forces you to use the "Wide Transparency" mode which can only be done through the lower resolution sensor/optics. To use the better optics, you have to select normal transparency mode, for which the focal plane lies considerably above the glass.

Hi yuexiachou29,
The pros and cons are discussed in detail elsewhere on the forum; I suggested it to you in order to hide scratches and reduce grain, which is why some people prefer wet-mounting.
But you should consider it only after the other variables have been eliminated: film grain, scanner settings, exposure and development, etc.
I prefer to dry-mount on the Epson (8x10 and 4x5); I never noticed a huge difference when wet-scanning, then again, I didn't have scratched scanner glass.
If the scratches are small, you can easily get rid of them in PS; it's inconvenient, but not terrible.
Or you can simply replace the scanner glass for about $45: http://www.ebay.com/itm/Epson-Perfec...AAAOSwbqpT82y9
Good luck!

I have a 750 that has scratches... then I found a 500 at a garage sale for a good price and swapped the glass..bottom glass anyway

the screws are under the little rubber pads

Hi everyone

thank you very much for the attention. I reset all the adjustments on epson scanning software, it looked a lot better.
I think the noise might be from the "medium sharpening"

underexpose & noise relation is new to me, I am still learning.

wax? scratches are everywhere.
How would you wax it?

There are waxes for auto windshields that will fill in minor scratches. Look for "Meguiar's" brand. This might make the scratches much less obvious, at least it works that way on windshields.

You may be able to buy a new piece of glass directly from Epson.
