Get Steve Anchell's book: The Film developing cookbook and learn all about asorbic Acid amidol chlorhydroquine glycin hydroquinone metol para-aminophenol para-phenylenediamine phenidone pyrocatechin pyrogallol

good luck.

I don't have the time nor money to always look up something in a book especially if I have to buy it. Things are difficult for me now and I can't afford to buy a book for a few simple chemistry points so I would of prefered to hear a streight up answer for this question of what chemicals are used to make film. I feel your just dodging the answer because it takes a little bit of writting, if your going to be on a web page say something half way intelligent or eles nothing at all I don't need advertisement advice i just want a simple enough question answered so thanks for leading me into another load of B.S. Hell I thought the internet was to be used to get actual info. instead of some deminished advertisement I'm sure the other person who wrote to you said the same. thanks for nothing i won't try your sight ever again.

Actually Holly the fact is that this question has been asked many times before and if you had taken the time and initiative to research and look at the archives you would have found the answer. Furthermore, sure the internet is for information gathering, but not for us to do YOUR job, wheter you are in school or work. The people who took the time to ansewer, were doing so to GUIDE you, not to answer you so that you could have copied the text and paste it on your research. Another thing you critzism of Ed is unfounded, not only does he monitor this groups, for free. On his site he has some very useful information which could have aided you in YOUR research, remember it is YOU who is doing the research not us, and any help of guidance you get from this site should be welcome by you. If you wanted us to do your homework, why didn't you say so and we would have ignored your post. Beside, I am sure nearby where you are there is a big brick building calles a LIBRARY. Funny thing, they don't charge you for the books, let you look at them for as long as you want, and you are or will be paying for this service with your taxes! So instead of complaining and whining, buck up and WORK....
