There are times when one wishes to add just a “simple” static photo to improve feel and presentation of our/client’s site or photo blog. The idea usually goes like this:
For the following part, we will need to be comfortable with a simple editing of html code, preparing JSON list of our photos, including jQuery/Ajax script, and with a little bit of css styling.
After many years of working with Windows XP OS, I recently (and finally) upgraded my OS system to Windows 7. I liked the XP system quite a lot, however, with so many recent software applications that were only working under newer OSs (e.g., Adobe Lightroom 4), I realized that it was the time to move on. I did a “clean” install on my current C: partition, which obviously meant that I lost all my programs and settings as installation went through the partition formatting. Another challenge was to maintain my disk partitioning scheme as I am used to have four partitions:
Since C: partition contains Windows registry, links and registration info for the remaining software on those other partitions is lost. Having so many customizations and applications working well on my XP machine, I did not feel like losing them all at once. This is where the virtual machine comes in.

While writing my previous posts on color management and web browsers [1, 2], I realized that instead of guessing as to whether a browser understands how to manage colors, a few measurements of color patches would go a long way. Questions, such as, what will happen with untagged images in Chrome 11 or is it safe to use sRGB profile for photos displayed on a wide-gamut monitor would then be easier to answer. By all means, these questions are not trivial and would deserve an in-depth study of the browser documentation and perhaps many hours spent on Google. Unfortunately, with many browsers one would still be unclear on the exact way by which are the (un)tagged images processed.
To address browser color capabilities in the most straightforward way, we would just send images of RGB primaries through the browser and record their colorimetric values. In order to do that, we would need a set of images that are either untagged (no color space information is associated with them) or images that carry color space information in the form of icc/icm profile. After the measurement is done, a quick comparison with known CIE 1931 chromaticity coordinates of RGB primaries of standard color spaces (sRGB, Adobe98 RGB, Pro Photo RGB) would reveal any color processing done by the browser. To measure the radiometric output, we can use the same device that we use to calibrate our display.
In my previous post, I provided a step-by-step guide to enable full color management in the Mozilla Firefox browser. While Firefox handles colors in a very respectful way, there are other browsers that cannot be setup (yet) to effectively manage colors (IE, Opera). For some time, Google Chrome was not capable of managing colors also or its setup was just undocumented. However, while there are several pages on the Internet describing how to enable color management in Chrome, results are often unreliable (read more below).
This post will show modification in a simple start-up option that enables management of colors in the Chrome browser (I am intentionally avoiding the term “color management” for the reasons explained below).
