Hi, i am a beginner and just trying to learn how to scan color negatives.
I use VueScan, trying to figure it out and have several questions.
I have read somewhere that it is better to do Histogram manipulation, color
balancing, possibly apply curve tool and some other stuff DURING the
scanning process rather than in Photoshop later on.
Unfortunately, i can't remember why (something about the dynamic range?)

So, would applying histogram modifications, etc. to RAW scanned file be
different from applying it during scan process?

Also, what is the best way to do batch scanning? I would like to preview the
pictures, make adjustments if necessary and then scan them all as fast as
possible. Do I even need to preview or is it better to do raw scans of all
pics and then making adjustments and saving without even touching the
scanner? Any other options?
In particular, I did not really understand the "lock exposure" thing for
batch scanning.

Thanks,
Denis

Denis:

Histogram manipulation, color balancing, and applying curves during
the scanning process are really only needed if your scanner does NOT
output 48-bit image files (and your image editing software can handle
48-bit images). Once the image is in 24-bit, histogram manipulation,
color balancing, and applying curves can create gaps in the histogram
(combing), that is a loss of information potentially leading to
posterization. The effects of histogram combing depend upon your
images, how you print them, and your personal tastes.

I suggest you get Wayne Fulton's scanning book at
www.scantips.com. It is inexpensive and simply the best. It was the
best investment I made when I started out.

Let us know what type of scanner you have and we may be able to help
you more with your other questions.

Thanks,

I actually read Scan Tips or most of it
I have Scanwit 2740 Film scanner, that can take 6 color negatives.
So I am thinking of what would be the best way to scan a lot of my negatives
in the fastest way.

Thanks,

I was playing for a while with the VueScan.
So as far as I understand preview is not really needed right?
Then, the workflow I would like to use would be:
1. scan once with hi-res
2. Tweak
3. Save with tweaked settings to TIFF
Does it make sense?

I was trying to make it work, but for some reason I always had Scan pass 1
and scan pass 2 for each photo even then I specified 1-pass scan.

Any ideas?

No, the Preview is needed to determine exposure time and color
balance.

Which is consistent with the above explanation. One (lower resolution)
preview for exposure determination, and one final Scan with the
(usually higher) exposure which will take longer due to the additional
exposure time and finer scan steps.

negatives at least, you need to:

1. Use the advanced workflow and lock the exposure and film base
colour.
2. Have the "Preview" resolution set to the required scan resolution.
3. Tick the "Scan from Preview" box.

Do a preview as normal, this will scan the film at the required
resolution, alter the crop, colour balance etc as required.

Pressing the "Scan" button will then do a scan from the image in
memory, WITHOUT doing a second pass of the film with the scanner.

Save the "Scan" image as normal.

Hope this helps

Steve.
