Re: Lighting for Platinum/palladium Alt proc Work Area
Thanks so much for the response. Now all I have to do is make
so good images.

I coat under full on tungsten light (probably a 100 watt bulb in

prints, though, in a closet and generally turn the light off when
leaving the room to let the prints dry. BUT I generally do not do
this with either Van Dyke Brown or Salt as both are more prone to
fogging and are silver processes. So it depends on what your
process of choice is. I used to use yellow bug lights but found
this very difficult with some processes including yellow
dichromate, and when I found out that Laura Gilpin of historic fame
coated her pt/pd prints in daylight I thought what the heck.
I also eyeball register over a light box that has fluorescent tubes
in it with nary a problem, but the light from that has to go
through thick plastic and the back of the paper to fog a print and
it isn't on the lightbox long enough to matter.
You could always do a test: keep a coated print out, and cover all
but a strip with a black photo bag. Every 5 minutes move it an
inch. Develop and see if you have stripes.
With many processes that take long exposures it just isn't a problem.

Do NOT coat under fluorescent lighting. They emit UV and most
"sages" say that they can cause fog in UV sensitive processes.
Most say that dim tungsten is fine but I also take the extra
precaution of coating under yellow "bug bulbs".

I use 25 watt yellow bug-lite bulbs in both dry and wet areas when
working on alt process prints.

Thta's true Brian,
I coat under a tungsten filament lamp (normal bulb), not tungsten
halogen or similar (I'm not sure about them). I also have coated
under flourescent lamps.

Thanks in advance
