Default Coupla questions (like I only ever have one, right?)

#1) Am I missing something or does PMK Pyro last about a day after
mixed? I thought it stored longer...I developed identical rolls a day
apart and the second roll, same film, same times, came out
empty..Maybe I screwed up the roll but just wondering...

#2) Anyone know of any Photograph/Photographic related RSS feeds?

#3) Does anyone do any Night infrared photography? I do and want to
chat with others that do it. Sounds oxymoronical but it isn't with
the right tools

Oh and finally, i'm looking for old old old unexposed and expired roll
film (at least 10-15 years expired). Of course will pay for
S&H/whatever or pickup (if you somehow live in VT). 35/120/127/220
also film 8mm/16mm and 70mm. BW preferred. Older the better
(1950's-1960's is my favorite). Email me if you want to dump a ton of
it on me. See my website for email addy.

IMOP:

Once you mix A+B you measure the lifespan in minutes versus
days. If you just mix the A component to dilution, in water you can add B
just before use.

#3) Does anyone do any Night infrared photography? I do and want to
chat with others that do it. Sounds oxymoronical but it isn't with
the right tools


I've been playing around with extended exposures in moonlight, nothing
involving IR though. I'm curious if you have any galleries though, I'd
like to see what it looks like - and I might be interested in delving
into it.

Parts A and B last indefinitely unmixed, but mixed, you have enough time for one
roll of film and that is it. It exhausts (by oxidation, I believe), turns brown
and is finished.


#2) Anyone know of any Photograph/Photographic related RSS feeds?


What is an RSS feed?

Can't help you there, either.

I often find that a few dealers at photographic fairs will bring such film in
case someone like you is interested. Check out Photorama.com for a show near
you. You can usually find someone with old film at the Boston Photographica,
each April and October, sponsored by the New England Photographic Historical
Society, which has a web site for details.

IYAO (In your Accurate Opinion):

Guess I read the directions wrong..I figured it would last at least a
day or two...I made enough for about 3 120's, used two, and the third
came out clear as piece of glass.

Thanks for the heads up..

saddening, though! (my fault, I know)

The moon doesn't give off you-know-what for IR even with highly
sensitive IR film (digital, neither)...I suppose if you measured what
nm the moon was projecting the most of you could filter out the rest
but I doubt it'd be any fun...but definitely worth thinking about!
I've done the sun broad daylight with 87's and 18's (uv) during that
sunspot and got some great shots at something ridiculous like f/64 @
1/4000

There's two ways I do night IR photog:

One way is to use IR film and an SB80DX flash "cranked" (eg. M)
covered with exposed film (which does a mighty fine job of blocking
visible light and letting in only near-IR). At night you push
something like HIE to around 800-1600, and bracket, bracket, bracket.
I don't have any images online yet but they'll eventually get there.
I've also done this with "2 million candlepower" spot beams.


The other way which is far easier if you have a digital slr (i'm using
d100's and d1x's) is to throw an 87 filter on the camera with a flash
(e.g. same as above) and crank that as well using exposures i've
measured pretty good night IR shots at about 30 seconds F2/8 with a
flash distance measured at 66'. Make sure your camera has digital
noise reduction or it'll look real, real bad. Once done dump to
photoshop and trash the color and neaten up the exposure (use RAW
mode!)

or something.

involving IR though. I'm curious if you have any galleries though, I'd
