Mikael Risedal: why cant that be true?raw is raw and as long their are no clipping in any channel you can do the WB later on against for example white or grey surface which is done anyway
and again there are other solutions than adobes, like www.qpcard.com which is easier, cheaper, faster and better
First, it depends on the balancing algorithm, some will cause clipping where raw data is not clipped.
Second, the starting point for the exposure when one shoots for calibration and profiling is what incident exposure meter tells, and that is far from clipping. One can bracket from there up and compare results - preferably, using numbers, and not eyeballing; as we are talking calibration and profiling here.
Third, close to clipping point is where one can easily run into non-linearities, and skew the profile.
I have a QPCard and see no magic in it. It glares under the daylight, it is not durable in the field, and I do not see it providing better accuracy. I wonder how it is easier. Speed is irrelevant. Price is not significantly lower; replacing it twice as often as Passport eats out any savings.
If you wish I can collect some QPCards and measure them to see if the manufacturing tolerances and aging affect accuracy. It is easy with a spectrophotometer ;)
john Clinch: Do different cameras of the same make and model see color differently. If they do why? I've never heard of sample variation between cameras AF fine tune aside
6% difference easy. No 2 sensor batches are exactly the same.
Steve, the following needs a complete revision:"As I am capturing raw files, I will have the camera set to the AdobeRGB color space and not sRGB, which is better suited to JPEG shooting. AdobeRGB gives a wider color gamut, and is the best option for raw images that will subsequently be edited on a computer. You should use the same color space for both the calibration shot and subsequent images which will use the same profile."
The colour space setting in the camera does not affect raw data.
Kuturgan: Why not to show todays Sochi? It is not the same city as it was 5 years ago.

Waimak Stud: Um... Priorities? A country that doesn't yet want people to have equal freedoms under the law wants to send an Olympic torch into space? That doesn't make you look great, it kinda just makes you look like d1cks.

Slava123: An utterly pointless waste of money. This is what separates us from the animals. It's beautiful.
Is it a stylized pole axe on the photo #2?
One category is missing - shots made with self-made digital cameras.
BJN: Getting a "neutral" white balance is important if you're shooting products or artwork and need the color rendition to be true to a particular daylight color balance. But for the vast majority of images, you don't want to neutralize color to render a neutral gray. Warm or cold ambient lighting is often what makes an image work. Most photographers shouldn't bother with color targets and white balance lens caps. They're specialty tools and if you don't know that you need them for you probably don't need them at all.
Yes and no. Most of raw converters use colour profiles that assume neutral white balance; and often it is better to start with a neutral image and add the feel of light at a later stage, in a controllable manner.
IMHO Mr. Sharma's book together with Mr. Rodney's "Color Management for Photographers: Hands on Techniques for Photoshop Users" deserve the first place; while ColorThink Pro should be the second most important tool, as some profile analysis, quality control, and comparison are very obviously needed. BabelColor and basICColor are very worth a special mention.
