Cyan, actually.

Something odd is happening. I shot some pictures in RAW format. They
previewed correctly on the camera, and when viewed using either Canon's
ZoomBrowser utility, or Breeze Browser, they appear correct. When converted
to a TIFF by either program, however, the shots display a strong cyan cast,
but only when viewed in Photoshop or Photoshop Elements (note: I'm not using
the RAW plugin to convert these -- they were converted either by
BreezeBrowser or Canon's own ZoomBrowser).

Even odder, if I open the converted TIFF in Paintshop Pro (Jasc's image
manipulation software) the image appears correct -- no cyan cast. I even
tried re-saving the image from Jasc, both as a TIFF, a BMP and a JPEG
(maximum quality). The JPEG has an extreme posterized appearance when
viewed with any program. The BMP and JPEG look fine in Paintshop Pro but,
again, when opened in Photoshop or Photoshop Elements, displays the same
cyan cast.

Any idea what's happening, here?

If you will upload an image to webspace somewhere and post a url, we could
take a closer look. (Post the raw file itself)

First of all, was the original image shot in daylight, shadow, or something
that has a color cast to it, like tungsten light or fluorescent light?
Secondly, what was the white balance setting in the 10D camera? If your answer
is "Auto" then you are leaving a lot up to chance. Thirdly, is your computer
system color calibrated? Are you viewing color files that are 48-bits, 24-bits,
or JPEG?

Most likely because Photoshop relies on ICM color management and you have a bad
profile somewhere in the flow, probably the monitor profile. See if you have a
monitor ICM profile ... Photoshop will use this, PSP might not (depending on
how it's set up), and if it's wrong you will get a color cast.

The ICM flow works great when all the profiles are correct but can cause severe
problems when a profile is wrong.

If you want help in tracking down the monitor profile let us know what OS
you're using and what version of Photoshop.

I'll try to do that when I get home.

Nope, it was a daylight shot, no shadows. The shot looks fine in
ZoomBrowser, BreezeBrowser (both of which, I assume, are looking at the
attached JPEG) and opens fine in Paintshop Pro (which is reading the actual
converted TIFF).

It was auto, but that doesn't explain the discrepancy between how Photoshop
(and Elements) displays the image and how it is displayed in Paintshop Pro,
ZoomBrowser and BreezeBrowser. There's nothing wrong with white balance
applied by the camera -- there is, however, something peculiar about the
resulting file.

Yes.

Paintshop Pro, Photoshop and Elements are all viewing the converted TIFF at
48-bits. ZoomBrower and BreezeBrowser are looking at the attached JPEG.
After conversion, ZoomBrowser and BreezeBrowser are looking at the 48-bit
TIFF.

Ah, that makes sense. I use a monitor profile created by my Colorvision
software. I'll try re-calibrating the monitor tonight.

It's Win2000 SP4, Photoshop 7.0 (and Elements 2.0).

Thanks!

I use the Colorvision Sypder too and get pretty good results with it. One
thing to watch for, if you've ever run Adobe Gamma utility it creates a profile
too and also a gamma loader.exe file that loads the profile values into the
video card when you turn on the computer. You're supposed to delete the gamma
loader (from the Start file) if you generate a Sypder profile too, else both
profiles get written to the video card LUT, with very bad results.

I noticed that if you have Photoshop loaded and have the gamma loader deleted,
then load Elements it looks like Elements re-creates the gamma loader, so you
have to delete it again. Check to see if somehow this has happened?

Another good idea! I'll check to make sure it didn't somehow get reloaded.

Thanks!

Could it be down to colourspace awareness?
