![]() Papers tend to have warmer white points much of the time, so the common default of 6500k makes white on a computer screen look quite a bit whiter than it does on print. Things get more complicated when you involve print. There is no guarantee of this, of course, as screen vary in minute to major ways for a very wide variety of reasons, but it is a reasonable baseline. Adobe RGB also uses a 6500k white point.) Using 6500k will mean that what you see with your calibrated display will generally be very similar to what your viewers see when they browse your work online. Most images saved for viewing on a computer screen should be saved using the sRGB color profile when possible (using a wider gamut, such as Adobe RGB, may be necessary if your image has very vibrant colors, particularly greens, but also reds and violets, as sRGB is a more limited white point. The color profile sRGB, a standard and very widely used color gamut, is also aligned to a 6500k white point. That is a very common white point, and the default for many computer screens, particularly lower-end ones. If you really don't care much about print, and only really exhibit your work online, you might want to stick with a white point of 6500k. ![]() you publish your work to Flickr, 1x.com, etc.) and print. A couple of the most common viewing mediums are on a computer screen (i.e. There is no single correct, standard viewing environment, and depending on how you normally publish your images, the white-point you select may be different than other photographers. The main reason we set a white point is to match the "white" on screen to the "white" of the material and environment in which your photos will be viewed. The key reason why we set a white point is not so that it appears "white" to our eyes. Some screens often come with a built-in range of settings, such as 5000k, 5500k, 6500k, and some even as high as 7500k and 9300k or around there (which have a bluish tinge to them.) As you noted, most screens these days are calibrated by default to a white point of 6500k, which appears to be more white than lower values. To start the discussion, lets start in the middle: Sunlight has a white-point of about 5500k (although it tends to range in reality from between 5000k and 6000k). ![]() White point from the perspective of the human eye is a very subjective thing, as the eye automatically "recalibrates" itself to differing white points depending on the kind of light that dominates a scene. This can be a complex answer, and quite often, the outcome is that it depends what you print on, meaning you might need to change it or recalibrate often.
