Vuescan Histogram Color Battle Lost? (8.1.2)

The Green Button is now gray :-) but I am afraid we lost
the battle to get the gray (luminance 50%) background
for the histogram panels...

I forgot with which version they became white, like a
blinding light (7.678 is still gray). I remember that
several people asked for the previously used std. gray
and in one version they returned to this color.

Maybe we could than add an option in prefs to satisfy
the friends of both gray and white panels?

I'd say, if the button color can be changed by request, there must be
some hope left for an important change like being able to properly
judge the preview...

I believe it was an eye soothing gray for 2 versions before Ed changed
it to blinding white. I have no idea why he did that.

I agree it would be an acceptable compromise, but it is still better
to have it gray, period.

A gray background allows better judgement of tonality, esp. in the
image shadows. It also is more comforting to the eyes. It makes it
easier to judge color, because we have a built-in neutral reference.
It reduces the amount of ambient reflection caused by the screen
emission in a darkened environment, which also helps to reduce eye
fatigue and color contamination e.g. from people wearing brightly
colored clothes. Neutral backgrounds are mandatory for quality color
judgement/adjustment.

Hi all,

An OT question I have for some time, what GUI toolkit is being used in
Vuescan?

Something called wxwindows, if memory serves.

BTW, in OS X the brightness slider often 'sticks' to the mouse even
after the mouse button has been released. Never happens with any of the
other controls. Been like this for a few versions, now. Has anyone else
noted this?

Truthfully, I forgot about this. I'll put it at the top
of my list, and will probably do it in the next few hours.

Whenever I see multiple people ask for the same thing,
(and especially if it isn't a lot of work), I put it at
the top of my list of things to do.

In VueScan's latest version 8.1.4 I discovered that the background for the
histogram panels is grey. Therefore ThomasH should be glad :-)

But in Bart's and my (and some others) opinion we think it is more important
that the background of the preview, scan and also the option panel is also
grey...

I agree with Bart's writing in another posting earlier in this tread:
"A gray background allows better judgement of tonality, esp. in the
image shadows. It also is more comforting to the eyes. It makes it
easier to judge color, because we have a built-in neutral reference.
It reduces the amount of ambient reflection caused by the screen

I'll add my vote to that.

The histogram panals are fixed in 8.1.4, now can the preview and scan
panels be fixed too? They are still white on my XP GUI and are more
important to judging colors than the histogram panels.

Thanks.

Sure thing - I'll do this for 8.1.5.

Great. Could you please make sure it will be a real neutral gray
background for the preview, because the current background color is
RGB 236/233/216 on my system (may have to do with Windows defaults).
An off-gray background will not help in colorbalancing.

Bart
 
I read RGB 236/233/216 as well - Windows XP on a Dell PC.

Thank you in advance for a neutral gray,

Maris
 
Do you think this slightly warm "white" that you and Bart are
measuring may be associated with your monitor if it is calibrated to
D65 whitepoint?

Jeff
 
The background of the 6 VueScan left hand tabs and the Preview and
Scan tabs is RGB 247/247/249 and the background of the Preview and
Scan Histogram tabs is RGB 224/223/227 on my XP box and
calibrated/profiled CRT.

Hm... on WinME and W2000 all panels were gray...

I am curious: How do you measure the RGB values on an arbitrary
window? Do you make a window dump and analyze than the colors or
do we have a tool around to do just that?

Hello Thomas,
There is a very neat and small application for Windows that does the
trick. It is called "Colorpicker". I can post the zip, only about 8
kB, on any binary group convenient to you if you want it. The newest
version needs a DLL I don't seem to have, and the one I use may need
a DLL you don't have, so...
Let me know if you want to try it.

Regards,
Alex

Yes, this is something Windows XP is doing - something to
do with themes I think. I'm pretty sure I can override this
in the Preview/Scan tabs.

Ed Hamrick
