Frank, I am assuming this is an hourly rental or a day structure; 1/2 or
full day. Besides the scanning time, are you also being charged to write
your files to your own media? or are you hooking up your own external drive?
Did you give your self some test files to play with at various setting
keeping the scanned area at the same ppi? This allows you to run a few sets
of tests to see what those scan software setting are doing to your images. 

 

 

I remember it (-120)  being the actual  off setting or true 0.  I typically
give my self a little above and below clipping points dmax and dmin, and
highly recommend it on a rented scanner to avoid clipping. See what they
have defaults set to but you don't want to waste time rescanning only
because you clipped your detail some place.

We live and learn.
I rented time and the scans are ok, but not great.
I'll do better next time now that I'm more familiar with the interface and
will be less panicked about maximizing my rental time at the lab. I could
use a little more clarification from users please:

Re: USM at -120
I had the usm palette boxes all set to 0 (one of the usm settings, I forget
which, kept defaulting to 1) and indeed the grain is pronounced in some
negs.
Is -120 a general consensus done by empirical testing, or a rcommendation by
flexcolor ?

Using photokit after - do you change mode to rgb> select Capture sharpeer>35
fast negative (as appropriate) > medium edge sharpen (as appropriate ?

AF icon (auto focus?) - there is a little AF icon/button - should this be
'dark' or 'light/faded' ? Some scans appear a tad soft?

Gamma - is there a place to set this to 2.2 ? 

I used the levels histogram, and found that the A (auto) worked well to
bring the white and black points to the edges of the histogram. I could
manually change them as well as the midpoint. And I could also change the
midtones with Gradations/curves. But...my scans are still mostly too light
and flat.

I selected Greyscale 16 bit B&W negative. I figured that the film grain
would overide a bit of noise and the benefit of rgb. The files were 100mb
anyway as GS.

What is the maximum Optical (non interpolated) res of the Imacon (848) - I
used 6300ppi.

Unfortunately there was no-one to train me just a young person that clearly
didn't know the answers to any of this.

Thanks for any further clarification.
Frank
