Color problem with scanner and/or computer

[Peter^]

I'm still having this major problem with the colors from the newest version of Silverfast Ai. Here is a comparison of an image I scanned a few months ago with the older version and then rescanned now with the new version. On my computer (even in this post), the colors look completely different. The first one is ok, but on the second the colors are much too intense. But on my computer at work, they look alike.

Do you guys see a difference?
What could be the cause of this?

the second looks like the scanner overexposed the negative and increased the highlights (with very intense vibrance). My first attempt at a solution would be to decrease exposure through silverfast.

Can't give specifics, as I don't really know Silverfast AI, but I do see a huge difference between the two photos.

Thanks - thought I was going crazy.
Like I said , at work the pictures look the same. There I am on Windows XP. At home, where I have the problem, I am on Windows 7.

Which OS do you use?

I'm using Mac OSX, could be a difference of screen calibration at home vs office...

That sounds like what I'm seeing too. The sky in the second is completely gone. I don't have Silverfast but does it let you have the program "meter" (for lack of a better term) more towards the center? In Vuescan, if it "sees" too much of the edge it can produce funny results.

I know why they look the same on your computer at work and different on a (good) computer.

The new image has a color profile SFprofT (MF Scanner). The first image has a color profile Adobe RGB.

These look the same on a browser without color management. Windows/Explorer at work?

But, what to do about this? Open the new file in Photoshop. Edit... Assign Profile... Adobe RGB. Now the images look very similar. (I'm on Mac, and of course Photoshop is a color-managed viewer.)

How to prevent it? I don't know.

Color management is endlessly confusing.

When you publish images to the web, you'll have better luck if you do Edit... Convert to Profile... sRGB.

Many many thanks! This looks like it could be the explanation.
