Color Management controls how digital colors look.
Learn how it works.
As with the Color Management Policy Section of Photoshop's Color
Settings, it is important to have a solid grasp of Color Management in order to reproduce
colors correctly when working in Photoshop.
As its name suggests, Color Management is just that: managing color. Its objective is to reproduce
colors as identically as possible, even across different computing or digital hardware environments. To that end, it embeds
ICC Profiles into graphics, When a destination device of any kind receives an image, the embedded profile tells it what color
space was used to create the image. For this reason, the ICC Profiles that communicate color space play a most important
role.
When using Photoshop, you may sometimes see alert dialogs such as "No Profile Present" or "Profiles
Do Not Match" when you open a graphic file. These alerts indicate that the ICC Profile in your Photoshop's Color Settings
does not match the ICC Profile embedded in the graphic file that you are opening. A file opened with an inappropriate profile
setting will be displayed with the wrong colors, and no amount of color retouching, however thorough, will get the correct
colors to the destination device.

While many recent digital camera models use
the sRGB color space to store images, these images do not have profiles embedded within them. Photoshop
conveniently recognizes them as being sRGB. Nevertheless, if you open a file whose color space you
are not really sure of, and convert it to sRGB, the colors will not come out right.
Note that Exif is a digital camera image file format standard defined by the Japanese Electronic Industry Development
Association (JEIDA), now part of the Japan Electronics and Information Technology Industries Association (JEITA).
As you can see, knowing about the color space of an image made by a digital camera is crucial when you open it. |
