Strange image display issue

Hey guys, I'm having a real issue at the minute with an image I took today.

The image is of a swan on a pond at sunset. In photoshop the image looks just as I want it. I exported to jpeg and then had a look at it with the "windows picture and fax viewer". The image was noticably bluer. Thinking this might be a problem with the viewer rather than the image I opened the jpeg in my web browser and it looked fine, I reopened it in photoshop, again it looked fine.

Next, I saved a smaller jpeg for upload to the web. I checked it by opening the image in my web browser on my computer, all looked fine. Uploaded to my website and something really strange. I have put the image in a blog post. In the post itself the image has gone blue again, but, if you click the image, it looks how it is supposed to.

I've uploaded the image to redbubble, it looks just fine on redbubble.

The post on the blog is
http://beginningphotography.wordpress.com/2010/01/08/sun-snow-and-good-timing/

The image is clickable, but is a direct link to the same image, not a resize or anything. If you click the link the image gets noticable warmer.

So, I really need a couple of things if someone would be so kind. The first is for someone to confirm that they too experience the same thing when they look at the image on my blog. The second is for any explanation as to what might be happening.

You can imagine my concern here, are any of my images actually what I think they are?

The image in question is
sunset_swan_snow_2.jpg


which on my browser here looks just right when displayed on this forum.

I haven't experienced this with any other pics on my blog, so wondering if it is something funky with jpeg.

Only guess I've come up with is that I've saved the web version at 144ppi at 600*400, the original is 3888*2592 at 300ppi, but that fails to explain windows picture and fax viewer getting it wrong.

I'm at a complete loss, pls help.
 
Quick update, I've just had a look at another computer and indeed the image looks far too blue both on my blog and on redbubble. It's almost as if I have two different versions of the same shot.

It can't be my monitor as this doesn't apply accross any other shots, I've checked numerous images I have online on the other puter and they all look just fine. But something is making this particular image blue. Gargh.. Hair pull out time
 
Have you tried calibrating your monitor ?

I had similar issues ages ago when I was on windows and proper screen calibration resolved it.

I can't explain the technical stuff too well but it;s to do with the different ways in which different programs view colour profiles (i think :lol: )

Well on my 22" CRT monitor they all look virtually identical.

I must say they look a bit blue but that could easily be taken care of.

Well I'd say this has highlighted two issues, and the image in question doesn't seem to be the main problem.
Now I've booted up my laptop many of my images look blue and cold. Its lovely and warm on this monitor. Crap crap and crap.

Ok, monitor calibration, hints and tips?

For monitor calibration, unfortunately to do it properly you have to buy a device to do it e.g. a Huey or a Spyder or similar. They are not cheap (circa £50 to £100+) but are very very good and accurate and worth it !
 
The first thing you need to check out is that you're running your image editor in sRGB and not Adobe RGB. This is by far the most common reason for images appearing on the web differently to on your PC.

I checked out both versions of your image btw and they look identical, so I'd suspect a colour space incompatibility before looking any further.

I'm contemplating doing this in a much cruder fashion. 20p print from tesco, come home, compare it with the monitor, make a few adjustments to get the monitor looking how it should, repeat, and hopefully end up not too far away.

I've had a look at that, everything is setup to use sRGB. It's a complete mystery why it happened, but now I know how far out my monitor is it's going to be beneficial. The only annoying thing is I now realise that all those images I've posted and been proud of probably all look blue, cold and washed out to you lot... Oh dear.

I have check your EXIF and this is why
photoshop:ICCProfile = "Adobe RGB (1998)"
You need to convert to sRGB some browsers will read profiles and some will not.
in PS go to Edit and then Convert Profile

Ahh b****r, found the problem. I defined a new lightroom export preset the other day for exporting tiffs at 8 bit and forgot to set the colourspace. My apologies for being dismissive of that, I've been working in sRGB for the last two months since I got my camera, didn't realise what I'd done.

I've now "calibrated" this monitor based on the other two monitors I have available, my laptop and another desktop. It sits right in the middle of them, and fortunately only this particular image and a couple of others seem to be majorly affected. Next step, a couple of prints.

In view of Chaz's post having checked your EXIF it does appear something is assigning Adobe RGB to your images. You need to check that your camera and image editor are set to sRGB. If you use a separate raw editor then check that too as that could be assigning the Adobe colour space.
