0446 "Does the lighting and wall/ceiling/drape/furniture colors near my monitor "
0447 "matter? Good lighting is a prerequisite for proper image editing and for "
0448 "comparing prints to the image on your screen. If the lighting near your "
0449 "workstation is too bright, colors on your monitor look too dark, and "
0450 "conversely. If the light from the fixtures in your workroom have a low CRI "
0451 "(**color rendering index**, meaning you don't have full spectrum bulbs), or "
0452 "if the light in your workroom comes from a window and so varies as the "
0453 "weather and time of day varies (or worse, is filtered through colored "
0454 "drapery), or if the walls and ceiling are creating color casts on your "
0455 "monitor, then your editing process will *correct* color casts that don't "
0456 "really exist."
