steve kessel Posted July 14, 2011 Share #1 Posted July 14, 2011 Advertisement (gone after registration) I was surprised when I recently uploaded colour images onto websites (this one, flickr, etc) via Windows Internet Explorer and saw how much redder they appeared than in Lightrooom. More recently I tried Firefox and here the colour is practically perfect. My monitor is colour calibrated. Is there an explanation for this? Link to post Share on other sites More sharing options...
Advertisement Posted July 14, 2011 Posted July 14, 2011 Hi steve kessel, Take a look here Colour rendition in Windows Internet Explorer. I'm sure you'll find what you were looking for!
Matus Kalisky Posted July 14, 2011 Share #2 Posted July 14, 2011 Very simple. Your Lightroom allows for color management, the Explorer (as far as I know) ignores the embedded color profile and represents all the color data the same way - ignoring the embedded color profiles. In praxis - if you take an image in Lightroom which has say sRGB color profile, make a copy of it and convert the copy to different color profile - say Adobe 1998. The two images will look nearly the same (the differences will be at the extremes of hue and saturation because the two different color profiles cover different parts of color space). Now save both of these images and open them with what ever software (explorer, image viewer of choice, etc..) If the both images appear different - it means that the application does not represent the color data properly (the Adobe 1998 will be less saturated as it is large compared to sRGB). If they look nearly the same than the application, that the application is aware of the embedded color profiles and uses them to "translate" the image data before sending them to monitor. To see this difference you don't even need a calibrated monitor as you are looking just at relative differences between two images. I hope I got it right, I am no real expert ...

steve kessel Posted July 14, 2011 Author Share #3 Posted July 14, 2011 I understand most of what you're saying but I'm baffled. How can there be a situation where people create websites for disply of carefully crafted colour images and a giant of the industry ignores the colour profiles of the images? Or is there a way round this? Thanks Steve Link to post Share on other sites More sharing options...
pop Posted July 14, 2011 Share #4 Posted July 14, 2011 How can there be a situation where people create websites for disply of carefully crafted colour images and a giant of the industry ignores the colour profiles of the images? Said giant of the industry ignores much more than that. It is the seller which most consistently ignores and violates international standards, causing all publishers of web sites huge additional costs for accommodating both "real" and "proprietary variants of" HTML and CSS.

SJP Posted July 15, 2011 Share #5 Posted July 15, 2011 Still I kind of like Bill Gates:D He is the classic example of the fact that "being a nerd can lead to success", this is a useful message for my students. In fact if you take the Forbes top 10 or whatever the number of "nerds" is (surprisingly?) large, about 50% or so. Still I am perpetually struggling to keep PC alive (like the problems with XP, SP3 and IE8 - software from hell). Anyway, the Bill & Melinda gates foundation does a lot of good work and (for me) it shows that even being the richest person on earth can be combined with a certain amount of modesty.

adan Posted July 15, 2011 Share #6 Posted July 15, 2011 Or is there a way round this? Convert your images to the sRGB color space before saving a copy for Web use (you don't need to convert your originals). Just as you down-rez them and adjust the sharpening for Web use (you do, don't you?). In PhotoShop's "Save for Web" option there is a button that can be clicked to automatically convert every image to sRGB as a part of saving it (see below). BTW - I don't think which browser you use for uploading images, in itself, has any effect on the color. Try looking at images you uploaded with Firefox (or Safari), using Explorer for viewing. They will likely look just as red when viewed with Explorer. It is the browser used for VIEWING (and whether it is color-management-savvy or not) that affects how you see the images, once uploaded. Keep in mind that the VAST majority of computers/monitors in the world are not profiled, use some bluish white point (because it makes them appear brighter) and are usually set to their actual brightest setting as well. (Not to mention the millions of "smart" phones and iPads and iPad wannabees) Images saved for the Web in the big, professional color spaces (Adobe 1998, ProPhoto, Bruce RGB) will look really good to the 0.1% of users who have calibrated monitors and color-savvy browsers - and like c**p to the other 99.9% of the world. Choose your target audience. I have a profiled monitor and controlled brightness for preparing images for printing - but turn my monitor brightness 'way up when prepping images for the Web. Otherwise, on most other people's computers, they usually look much TOO light (with white points all over the place). Something I found out about 15 years ago. Welcome, dear visitor!

Jamie Roberts Posted July 16, 2011 Share #8 Posted July 16, 2011 I thought the latest release of IE would support embedded profiles. Perhaps you could have another look, but of course, I may be wrong Regards Per I think this is the best guide out there right now... Web browser color management guide It's a pretty good (and up-to-date) guide to the current state of affairs. The net is that only Firefox truly offers full colour management that works on color managed and wider gamut systems. IE9's colour management is evidently broken. Currently it ignores your monitor profile, which isn't bad if you have a monitor that is precisely sRGB (IE9 just assumes your monitor is sRGB). But most aren't quite (though close) and many now for photographic proofing these days are extended or even aRGB. Safari, interestingly enough, assumes your monitor is always that monitor's full gamut. That works for tagged sRGB images, and is ok for untagged images on a normal (sRGB-ish) gamut monitor, but *not* for untagged images on a wide gamut monitor. I like Chrome because of its speed and hack-proof-ness But it has no colour management whatsoever, really. Link to post Share on other sites More sharing options...
