Colour management issue

Just having a bit of a colour management issue here. For photo processing on the go, I have just moved to a new laptop with a wide-gamut screen, which I have calibrated. Images look fine in Photoshop or Firefox, and they look fine on my colour-calibrated, wide-gamut desktop monitors, but, when I upload a file to Flickr and view it in Internet Explorer (a non-colour managed environment) the photos all look oversaturated and with a strong red hue.

I suspect it's simply because the wide-gamut display means that colours appear more saturated in an unmanaged environment, but just thought I'd double check - do the following images look OK on your colour-managed browsers? How do they look in Internet Explorer browsers on a wide-gamut monitor? Do they look OK in Internet Explorer on a regular monitor?

Thanks in advance.

They look over saturated red on my retina Mac Book Pro in Safari. The upper edge of the slope in pic 2 is completely red. The hills in #3 are red.

Is that colour-managed? The retina displays are (relatively) wide-gamut, aren't they? Compared to sRGB, anyway.

Evaluate your 3 shots using a color histogram. The red channel is clipped on a 3 shots.

Fair point - there's no clipping in the Adobe RGB files, but, on conversion to sRGB, the reds are clipped. But the sRGB files still display properly in Photoshop and in Firefox - why would that be?

They display properly in PS and Firefox because both are fully color-managed applications.

But, if the sRGB files are clipped, then they shouldn't display properly, due to the clipping.

This doesn't help, but I really like the first image. I'd just like to see it with less red (it's super red) and maybe pulling the highlights back a little.

Post the images here in AdobeRGB, please.

On my (calibrated, wide-gamut) monitor, it's showing up as a sunrise orange - that's the issue here!

I'm guessing this is happening because these images fit into the aRGB gamut, but are wider than the sRGB gamut - hence, on conversion to sRGB, the red channel clips. Since most modern LCD monitors have a wider gamut than sRGB, viewing these images in a non-colour-managed environment causes the monitor to display RGB values of 255/g/b as red as possible; given that most monitors are capable of wider than sRGB, this causes the image to appear redder than intended.

Just checked it by using Assign Profile to assign my monitor's profile to the image, i.e. simulating a non-colour-managed environment in Photoshop, making a Red value of 255 display as the reddest the monitor can go. Sure enough, the whole image turned red, and looked as it did in Internet Explorer. I guess this means my monitor can display reds that are well beyond the Adobe RGB colour gamut.

OTOH, when I adjust the images to look good in a non-colour-managed environment, they look far too yellow when colour management is turned on.

Would someone be able to view the Adobe RGB and sRGB images I've posted in Photoshop (or another colour-managed environment) and tell me if they look OK or not?

You'd want to put the original jpeg files on a web server, file sharing services tend to mangle images and color profiles.

The images look near identical to each other in Firefox using my calibrated wide gamut NEC, calibrated to full gamut. At least as far as I can tell by scrolling up and down to compare them.

The first one is pretty orange and the other two are really red. The images are terrific though. Absolutely excellent work! I especially like the last one.

I brought both copies of the last one into Photoshop and they are tagged correctly (aRGB and sRGB). As expected, in PS both images look near identical and the same as they do in Firefox. If anything the aRGB images have a tiny bit deeper (richer?) colors ... maybe.

Thanks - looks like there may be something wrong with my monitor profile, then. I thought everything looked a bit yellowish when I calibrated it with my Spyder 3, and stayed that way when I calibrated it again, but just put it down to my eyes having gotten used to cooler colours while setting up the rest of the system. So, correcting for the yellow on my end means that everything turns out red on other systems.
