This points out the need for calibration and a large color space.

Here are the first five but you should read the rest.

. Manage the color. ICC profile-based color management is the
standard.

2. Calibrate the monitor. Monitors should be calibrated and profiled
with a hardware device.

3. Choose a wide gamut. Use a wide-gamut RGB color space (show
footnote) for capturing and editing RGB master files. We recommend
Adobe RGB (1998) or ProPhoto RGB.

Professional digital cameras have selectable color spaces. Photographs
intended for print should be captured in a wide-gamut space, such as
Adobe RGB (1998). Photographs intended only for the web can be
captured in the narrower-gamut sRGB color space. It is possible, but
not strictly necessary, to create custom camera profiles. When such
profiles work, they can speed workflow and yield more accurate colors.
Adobe’s Camera Raw program allows for calibration of a digital camera,
creating in effect a custom profile.

It’s essential that a photographer choose the correct color profile
when capturing JPEGs or TIFFs, because the camera will process images
into these formats using the specified profile.

4. Capture the raw data. For best quality, digital cameras should be
set to record RAW files.

5. Embed the profiles. All digital files should have embedded profiles
(should be “tagged”), unless otherwise noted. Photoshop’s Color
Management should be set to “always preserve embedded profiles,” and
the “ask when opening” boxes should be checked to alert you to profile
mismatches and missing profiles. When profile mismatches occur, you
should elect to preserve the embedded profile.
