[alt-photo] Re: dilution of pt/pd

As a last note (sorry for the stuttering posts):
Use ammonium (or lithium) based print out processes (which also eliminate
the ill defined FO, by replacing it with AFO) if you're afraid of
solarization; they don't exhibit this phenomenon...

Loris.

I've quoted your wrong sentece. For sake of clarification, my reply was to
your statement below:

"...The dilutions are the minimum amounts needed to avoid solarisation or
reversal..."

Terry,

I was to mention this to Christina; she'll have to watch for solarization in
case of perfectly matching Fe and noble metal.

But that's something easy to take under control, right?

(1.) Use adequate amnt. of solution per coating area
(2.) Do not overexpose
(3.) Add a little Pt (1:5)

Regards,
Loris.

The dilutions of 20% for the sodium tetrachloropaladate, potassium
tetrachloroplatinate and ferric oxalate enable me to achieve prints which
reflect the qualities of the negative .
