Color Management, Grayscale Charts and Monitor Adjustment
Color Management. In an effort to prepare digital images that meet industry standards as well as client expectations with regard to color and consistency, we have adopted the following standards. When working with digital images, the RGB space we work in is "Adobe RGB (1998)". To calibrate our monitors we use Colorvision's SpyderPRO and its accompanying OptiCal software, with a color temperature of 6500K (D65) and gamma of 2.2.
Monitor Adjustment. It is important to have your monitor adjusted properly in order to view our photographs or, for that matter, any website which displays images for which an effort is made to control color in a consistent, industry standard manner. (Yes, we realize that color management is still, in many ways, an elusive thing.) This means setting your monitor, either with its built-in on-screen controls or through software, so that the grays are rendered without any color cast and so that you can discern detail in shadows (at the darkest parts of the charts below) and in highlights (at the brightest parts of the charts below).
The grayscale chart above shows gradations of neutral gray from pure black to pure white. You should be able to discern differences in each gradation of gray, with the possible exception of the two or three darkest levels. There should be no color cast to any of the levels. This chart is created by changing the RGB colors in lockstep by increments of 8, e.g., (0,0,0), (8,8,8), (16,16,16), ..., (255, 255, 255). Or you can do it by incrementing the HSB values by about 3 each step, e.g. (0,0,0), (0,0,3), (0,0,6), ..., (0,0,100).
