(according to wiki... which also has a (poor?) example of it!)
I have seen several good examples of his process!
It produces the colors by interferance
(which to me is only vaguely understandable as something similar to a visual doppler effect... uh huh, uh, well anyway)
It can produce strikingly vivid and accurate colors.
It has some followers and wannabes (like myself), but there are servere difficulties with the procedure which keep it from being given the true respect it deserves.
I do believe it's day will come again!
BTW, the images can be viewed rather easily,
and can be also made without the Hg.
There used to be special camera backs sold commercially just for this sort of emulsion.
Ron, is it possible you had something else in mind?
