This is a negative working emulsion that contains cadmium. With care it can give some excellent negatives but you must only melt the amount you want to use each time. If you melt the whole thing, it changes and that is not good.
Making your own is not hard. Read my book! Just a plug for all of my time and money!

dr c..
if you can get silver nitrate cheap by all means try to make
your own emulsion. the emulsion aj12 instructions j loaded in the articles section
a long time go, it is pretty straight forward/ easy.
here are also lots of recipies over on the light farm website ..
i made my first emulsion when i was broke and i college in the middle of the night.
something like 30 years ago ..
i am confused about your questions about liquid light.
it is like paper emulsion ( or an emulsion you might make )
it prints a positive if you project a negative onto it, and it will give you a paper negative
if you stick it in your camera .. just like paper. there is a way to make a direct positive
that is with the tintype kit, but i dont think that is what you were talking about..
have fun!

Gladly! Got a link? Preferably to somewhere with cheapish shipping down here, or even an electronic version I can read while I'm at-my-desk-at-the-place-that-pays-me (note I'm avoiding using the 'w' word).
Well, I suppose your confusion comes from my confusion. FP4 and TMX are 'negative' films. MGiv and Ilfospeed and Crystal Archive RA4 are 'negative' papers. HDPP and Ilfochrome are 'positive' papers.
What I want to do is take a regular negative film and enlarge it onto a regular negative canvas, just like negative paper, to make a positive image. That's why I was confused when some people told me that LL is a 'positive' emulsion, I was imagining something like HDPP or a Tintype/Daguerrotype, which I don't want to make (yet, I'll leave that for another day).
I figure AgNO3 would be somewhere in there for a DIY-emulsion, not sure about how easy it is to get around here. Ringing around chemical shops might not be the best thing to do for me right now, I've been applying for some jobs at Defence contractors, that might be the sort of thing that would get my security-clearance denied (especially if I have to go the Ag + HNO3 route)...
Kodak researchers used a method similar to dye transfer to get a positive color image that you could only see under UV radiation. Then it fluoresced in full color

Just curious- why? What was the intended use, other than a fun project which I doubt was allowed (much) ?
