So, I was thinking about trying out this formula, but am a bit confused about how to dilute it. Anyone have any experience with this?
For instance, the following; "Sepia: 3 x normal exposure, dilute with 10 parts water, add 1ml 10% bromide solution, 5 minutes development." Dilute how much with 10 parts water? It's all mixed between ratios and ml. Huh?
Here's the formula from the book, mildly adjusted by me for better understanding:
Warm-tone Developer for Sepia-Red Tones (Ilford)
The Photographers Toning Book, Page 179, by Tim Rudman
Paper developer for warm-tone prints. This is not a toner.
Note: This is used to produce fine grain size and hence warm tones. This is often used with reduced development to minimize grain size, and overexposure to restore density. If development is restrained too far in the pursuit of warm tones, subsequent toning is likely to be weak.
Stock Solution:
750ml Water
3.4g Hydrochlorquinone
3.4g Hydroquinone
31.25g Sodium sulfite, anhydrous
23g Sodium carbonate, anhydrous
0.35g Potassium bromide
Water to make 1L
Note: I have not used this formula, but my own experiments with other warm-tone developers of this type suggest that the extreme warm-tone prints from maximum dilutions in such developers do not tone well.
Use: This developer may be used stock, or like many warm-tone developers, used at increasing dilutions & longer development times, for warmer-tone results. Addition of extra potassium bromide will give redder tones. The following guides are given, using a 10% (1+9) potassium bromide solution:
Warm Black: Normal exposure, undiluted, 1.5 minutes development.
Sepia: 3 x normal exposure, dilute with 10 parts water, add 1ml 10% bromide solution, 5 minutes development.
Brown sepia: 5 x normal exposure, dilute with 15 parts water, add 3ml 10% bromide solution, 10 minutes development.
Red-brown: 6 x normal exposure, dilute with 25 parts water, add 5ml 10% bromide solution, 15 minutes development.
Bright red: 7 x normal exposure, dilute with 30 parts water, add 5ml 10% bromide solution, 15 minutes development.
