Hi;

I've just posted a photo of a Steller's Jay to my gallery. It has a turquoise colour cast that does not show in Lightroom or in my jpg when veiwed on my computer using explorer. However, both here and on FLICKR it shows with this strange colour. Any ideas as to why it would be the same on both web sites yet so different on my system, afterall I'm viewing it on the same screen?

Thanks, Paul

I don't know the bird, Paul - but your Gallery image is near as dammit the exact same colour as this image (which I assume is the right colour) on my calibrated monitor, and I'm not seeing a colour cast.

Thanks Keith.
I too have a colour calibrated monitor. I agree the image you refered to is near the exact same. I just wonder if its a function of the web. The web image seems much more vibrant. If you give me your e-mail address I can send a jpg directly from my hard drive and then we'll know if I'm "seeing" things.

Colour management or lack of it by your webbrowser? I recall some issues with firefox in the past when CM was (still is?) turned off as default setting after installation. This can massively influence how colours are displayed. Google should turn up more info on this.

Follow up on my previous post:

Check this website.

It shows what can happen if a webbrowser is unable to apply the correct ICC profile to an image, either due to the lack of information embedded in the file or due to its own inability to do proper colo rmanagement.

Thanks Seaspirit;

According to this website my monitor is behaving correctly. That is, nothing happens when I rollover the left pane and when I rollover the right pane it changes and looks exactly the same as the left pane. I assume that's what is supposed to happen.

Yesterday I re-did my colour profile with my Eye-One Match 3 x-rite. There is still a slight difference between the colour of the jay in Lightroom as compared to what I see on the web, not much, but its there. My display is a Dell UltraSharp U2410 24-inch.

Once again, thanks for giving me the website re colour management. It has a lot of useful and interesting info.

Cheers, Paul

If you are saving your images for the web they need to be converted to srgb, if you don't the web page will convert them itself, this will in most cases give you a colour shift you didn't expect. If you are using Photoshop and Adobe RGB as your colour profile and saving your image as a jpg, then you will certainly get a colour shift if you submit it to a web page as is.

Thanks nirofo;

I used Lightroom to publish to flickr and it converts to sRGB colour porfile. However, just in case, I saved to jpg and uploaded manually ~~ same result. The diff is so slight that I've decided it is just one of "Them there internet thing-A-ma-Gigs".

cheers Paul
