- Ambient lighting:
The ambient lighting in a 5m x 5m room consists of one 60W light bulb,
one fluorescent tube and one "warm tone" fluorescent tube. Together.
So, it's a mess, I know. This is not a lab. I can choose either
incandescent or fluorescent, though. I don't know about light levels,
but it's generally dim (and warm).
Thats three colors of light (great for cross testing prints, but otherwise a disaster) and at least three times as much light as a room should have for color managed work. The rule of thumb is that CRTs should be used in the DARK. LCDs are somewhat brighter, but should still have dim lighting. My studio currently has one 13 watt color correct fluorescent lamp running, the blinds are shut, the shades are drawn (and its dark out, but its been configured this way all day, so that the outdoor lighting does not effect my inside conditions). Its not that I don't have more color correct lighting in the room; I can count at least seven 5000k lights within reach, with more in the closet; and for photography I might have several of them
running; but for editing, only one.
