Epson V850 Calibration & Sharpeness (120)

Hey everyone and sorry if this one has been covered before (I searched and can't find anything)

Fort 35mm I am using Epson V850 for quick proofs of the whole roll (much like a contact sheet) and then Plustek (which I find very sharp) to further work on selected frames. 

Due to this workflow I've not experimented so far with getting the best out of the V850, but I'm now starting 120 scanning so will be completing the whole process in the V850.    

Regarding optimising sharpness: I'm aware that the feet of the holder will move the image closer/farther from the fixed scanner lens and therefore effect sharpness, so I can experiment with that .  But I also read sometime ago these scanners can be 'calibrated'.  Is that the same thing (presumably with a commercially available 'target'), or is this 'calibration' referring to something different ?

Secondly, can any Lightroom users that are using V800 or V850 advise what level of additional sharpening you apply in Lightroom?  With the plustek I don't add much at all, maybe 12-15%

By the way if relevant, my processflow is Scan > Negative Lab Pro / Lightroom conversion > Final edits in Lightroom 

Thanks in advance for any tips.

@jakontil  I think you may use this kit ?

I'm pretty sure 'calibrating' is simply adjusting the feet of the holder, and it's well worth doing a few tests even if you end up back where you started. When I was doing my MF on my V700 I used a Betterscanning 120 neg holder that has screw feet which can be more finely adjusted, and my holder had ANR glass to make sure the negative is perfectly flat.

Good stuff Steve thanks .   I'd forgotten about ensuring the film is flat so I might invest in one of these - mine doesn't have glass although does have feet for changing the height

Aye mate!

hahaha i m using the V600 but i guess it is almost similar in terms of final image

flatbad is good for scanning 120 while a little bit demanding for 135 but it’s still great, besides you have plustek for anything more

the calibrating in v850 is referred to color calibration, say silverfast IT8 calibration, nothing to do with focus target

Each height of feet in the holder plays a major role, hence you will have to try each one of them which suits you best! Manually calibrated in a way mate

i might use v600, but my holder is of V800, this is how it related, and my best setting is to pull all feet off together, but mind you, mine is V600

 

for sharpening purposes, for 135 might also try on 120, set sharpness 100 and feather 2.0

some said add little clarity and texture, but in my experience it bcomes harsher

for 120 setting i usually leave it default settings in NLP menu, sharpness for lab scan? Which turned out 40 and feather 1.0 if not mistaken

Brilliant that's so helpful mate thanks a lot . Do you use Silverfast then?

If we are using NLP to convert the negative then do I need to colour calibrate the Scanner ? .  I'm using Vuescan not Silverfast. 

Thanks again - your scans look great.

I use silverfast the same way u use vuescan, since i have both apps, but for batch scanning im more familiar with silverfast, other than that they are the same, so dont worry, and since we are scanning raw files in DNG, i dont think we need to calibrate it

it is good for converting without the NLP I believe? Anyway i never calibrate it though
thanks man, basically all scans will be equal in quality since we all use the same conversion, have fun!

OK great, so only the sharpness to tweak then, that's encouraging !

Thanks again
