digital darkroom room color

I never painted mine in dark shades. It was always white, and the
safelight was set to appropriate brightness, which made things a lot
easier to see and find in the lab.

Mine to, never saw any point to a black darkroom. It just had to be
dark.


But aren't black walls darker when you turn the light off? :-)

(chuckle) Actually, yes they are. If you can see the black color, SOME
amount of light is being reflected, so removing the light source would
actually make the "black wall" reflect less light, and thus blacker.

But the main reason I always went with a mat black wall color was to
reduce the chance of stray reflected light causing trouble. Of course now
that I am using digital, a dark colored room, with a colored light, a
bunch of chemicals and a constantly flowing water tank is much less
desired. That's one of the advantages of going digital that I like. I
can do some fairly advanced "darkroom tricks" right there in my bedroom.
In fact I have done some fairly tricky stuff on a laptop, in a tent, on
a mountain top, a LONG way from the nearest room (not to mention dark
room).

ISO9100 requires you to paint the room gray. Any ambient light must be
5000K (and very dim). The monitor is to be set for D6500 for all except
pre-press work. Pre-press requires a D5000 setup.

Monkeys will fly out of my butt before I set my monitor to D5000.

any idea where i could read or download the iso requirements?

thanks,
paul

During the day, yes.
But I akways did my darkroom work at night.
Man, after dark, my darkroom was AWESOME!

The point is that ambient light affects your perception of print color more

Let a print dry and look at under different light sources, primarily
tungsten, daylight and the usual mixture of the two, before you decide on
whether the color balance is "correct" or not.

But a nice gray is helpful as is Graphite for a Mac when doing color
management.

Does the graphite just sit in a jar, or does it need to be sprinkled
over the keyboard?

If *I* were going to ask a question, it would have been, how did those
monkeys get *in* there?

No, it's a system pref which makes things a nice neutral gray.

It remove the gum drop colors of the window buttons.

Ah! OK, thanks!

It is useful if you have an enlarger that leaks light out of the
lamphouse and negative stage area. Black walls around the enlarger help
ensure the leaking light doesn't make it to the paper.

Of course, you could also get a better enlarger.
