I was interested in finding cheaper alternatives more than using what's commercially available for highly inflated prices. What are the essentials for making your own emulsion and coating paper?

As for adding red sensitivity, a good aggregating red sensitizer is available from H. W. Sands Corp. in Titusville Fla. This dye was discussed completely in another thread. It is a Green sensitizer on Bromide and Chloride emulsions and a Red sensitizer on Br/I emulsions due to "J" aggregation. It is used in Kodachrome film AAMOF. I have 0.9 grams of it here. I used 100 mg already. This dye runs about $300 / gram right now IIRC.

Do you know the name of this dye? I would like to try it.

There is almost a full thread on the dye in this same forum under another thread. Since there is some controversy over the exact number on the manufacturers web site, I don't want to rehash or repeat it here, but rather you should look at the other thread. I believe that wildbillbugman was the main contributor. I'm sorry, but I do not save URLs.
