Inverted Iron Blue toning. This combination of Iron Blue on the highlights with sulphide sepia in the blacks is more complex to achieve and requires 16 steps.
That is very interesting -- have done both 'Blue' and 'Sepia' on traditional Darkroom Prints but never knew you could 'combine' them as here .The Blue is easily spoiled by wrong pH baths.
@pentaxpete Yes. In outline (excluding intermediate washing stages) the toning scheme is roughly as follows:
Acid pre-condition
Iron Blue tone
Ferricyanide / halide Bleach
Sulphide Tone
Blue Tone Regeneration
Alkali differentiation
Final wash
That's impressive. I actually thought is was done on colour stock. Keeping the whites white and the snow shadows blue really sells it. The warmth of the chocolate brown sets it off very well.
The visualization that led to this is to be commended. I doubt I would have thought to try (let alone succeed)!
My early professional training was in analytical chemistry and I loved chemistry at school, so I just love B&W photographic chemistry. Complex and novel toning, often very extreme and 'punk' rather than purely pictoral, is a special interest of mine. I'm setting up a personal album to share a range of my work. Great site - and thanks for the positive comments.
