RE: Hazards of wet plate collodion ?

Kerik, thanks for the valuable info.

I am also interested in wet plate collodion. Specifically in ambrotypes.
>From what you wrote below I understand that ambrotypes fixed in sodium
thiosulfate are duller and have a more neutral hue when compared to
potassium cyanide fixed ones. Did I get it right? Do you (or others
practicing wet plate collodion) have scans of either hypo and cyanide fixed
ambrotypes so that I compare the results?

Thanks in advance,
Loris.

Diane,

You can use plain hypo to fix collodion images. Although many of the
wet-platers I know prefer cyanide (as do I), it's not required for the
process. Cyanide works much faster (not a big deal) and it tends to give a
brighter image and a warmer coffee-and-cream tonality to the ambros and
tins. The bottom line for me is I prefer the look of cyanide-fixed ambros
and tins over plain hypo. Since you're teaching yourself the process, I'd
suggest starting out with plain hypo. You may get what you're after and
never have to deal with cyanide.
