Color Management and the Web
One of the weaknesses of presenting photography via any digital publication method is the question about color fidelity. Fortunately, color management helps a lot, but not all devices and not all displaying applications are color managed. For example, this is one of the true weaknesses of tablet devices compared to most computer web browsers — although it must be said that a few browsers are not color managed either.
What does this mean for all of us? A quick and great demonstration is over at Jim Kasson's blog, The Last Word. You can check your monitor/application/device with his simple pair of test images. I can confirm his results that Chrome for Windows 7 is color managed (my computer) and that Chrome on the Nexus 7 is not. Neither is Safari on my original iPad.
It's definitely recommended that you color manage any images you post, but that does not guarantee that the viewer will see what you think they will see. Their device has to play along, or all bets are off. Just something to be aware of when you post your images.
