To find sulfur dioxide, just take a deep breath in any major city! LOL!!! All seriousness aside, it is easy to make sulfur dioxide from this: http://stores.photoformulary.com/search.php?search_query=sulfur+dioxide <http://stores.photoformulary.com/search.php?search_query=sulfur+dioxide&x=1 7&y=12> &x=17&y=12 To find diethanolamine look here: http://www.chemsavers.com/search.php?search_query=diethanolamine Yes, it is hard to find some of the proprietary Kodak dev ingredients but, though they are often expensive, they can be found.

For example the addition product of diethanolamine and sulfur dioxide. AFAIK and they are not commercially available.

You might have a heck of a time finding and stocking some of those more esoteric reagents in the formula. CHEERS!

While I am not married to this developer, it works well for my film. But I find "no longer available" and "not in stock; don't know when it will be" messages on mail order retailers. Another chink in the film supply/process world. Les Free Online Photosharing - Share your photos online with your friends and family!
