Re: Some Kallitype observations
FWIW, I proceeded to do developer-toner combos of sxs run prints and found the following:
a) 5% KOX - Au toned >>> cool brown shadows, tan-mauvish highlights.
b) 20% Na citrate - Au toned >>> cooler shadows and whiter highlights rel. to a).
c) 5% KOX - Pd toned >>> warm browns throughout tonal range
d) 20% Na cit - Pd toned >>> cooler browns than in c); slightly warmer than b) across the tonal range.
e) 5% KOX - Pt toned >>> as in c) but browns are slightly darker.
f) 20 % Na cit - Pt toned >>> very similar to d).
What I was interested in doing was establishing combos (under my working conditions) that would generate subtle color changes in the otherwise B/W Kallis. Double-toning also holds promise and all this becomes more apparent when the prints are viewed together.
Sandy King has shown this in his Unblinkingeye article. Other factors (water quality, humidity, sensitizer components, paper, etc) also contribute to the tones obtained.
