Color settings in new VueScan

[Andrey Tarasevich]

Hello

(I've seen this question asked before, but the thread went into an
irrelevant troll war right away and the original question was never
answered. So here it goes again: )

I noticed that the new version of VueScan supports per-frame color
settings in the 'Color' tab for batch scans. This is great and makes
perfect sense, but often it is also very useful to be able to batch-scan
several frames with exactly the same color settings. Is there any
convenient way to set-up such a scan (aside from the manual copying of
numerical values one-by-one from one frame to another)?

I tried to look into the user guide, but haven't found anything so far.

Hi Andrey,

I think that what you need is on the input tab:

preview, then check "lock exposure"
preview again, and a new check box will appear on the input tab, which
allows you to lock image color.

This is described in the guide somewhere. I don't really understand why
locking the exposure doesn't lock the color as well the first time, but
it works very well. I use it all the time when scanning 6x17
transparencies in several chunks on a Coolscan 9000 for subsequent
stitching.

No, that's not exactly what I'm talking about. In my case I need to have
identical neutral color values (r, g, b) for several frames. That's the
'Manual' color balance values that can be set by right-clicking the
neutral color in the image. They used to be global. Now they became
per-frame. I'd like to know if there's any way now to apply the values
set in one frame to other frames.

That's close, but that's still not exactly what I'm looking for. I don't
want to lock exposure, for example. I just want to lock the color
balance settings.

But aren't some of the color balance settings exposure-dependant?
(specificially, which settings are you talking about?)

As I said in my previous message, I'm talking about 'Neutral red',
'Neutral green' and 'Neutral blue' settings available in 'Color' tab in
'Manual' color balance mode.

Thanks for clarifying. My concern about this issue is why I'm still
using 8.3.43, as you noted that these values were universial in the
older versions (even with the cropping and other bugs). Let me know if
you need a copy of this version.

The best workflow I've managed is to preview one frame and set the
values as you wish (using the single frame preview option). Once you
have done this set to batch mode and scan all the frames you want.
(You should have done the lock exposure/lock film base/lock color
balance on the preview frame).
At this point all the frames will have the same settings. If you
change anything in a given frame it will be "uncoupled" from the
master settings.
I haven't found any other way to emulate the old version. I
wrote Ed Hamrick, but got no reply (yet).
