Classic Rodinal performance with modern reliability and versatility.
What It Is & Why It Matters
Adox Adonal is the contemporary successor to Agfa’s legendary Rodinal—utilizing the same formula and delivering superb sharpness and acutance. It’s a one-shot, highly concentrated liquid B&W film developer that adapts to any negative film via dilution. This makes it invaluable for photographers seeking control over grain and contrast in their images.
Key Features & Benefits
-
Classic Rodinal formula – Crafted from Agfa’s 2004 formula for edge-tone sharpness, tonal separation, and excellent acutance.
-
Highly concentrated & economical – A 500 ml bottle yields up to 50 rolls of 35 mm (1 + 50 dilution); even finer grain with up to 1 + 100 dilution.
-
One-shot developer – Ideal for precise control and minimal waste; simply dilute once and use.
-
Versatile contrast control – Lower dilution (1 + 25) creates pronounced grain and contrast; higher dilution (1 + 100) yields smoother tones with fine grain.
-
Long shelf life – Legendary longevity—Adonal retains full effectiveness even decades past opening.
-
Fine grain, crisp detail – Delivers exceptional sharpness while keeping grain minimal, especially at higher dilutions .
Usage Guidelines
-
Typical dilution: 1 + 50 general-purpose; increases clarity at 1 + 100, or punchy contrast at 1 + 25.
-
Mixing advice: At least 5 ml of concentrate per roll in shallow tanks ensures consistent development.
-
One-shot use: Discard after one use—optimal for consistency and to avoid contamination.
Safety & Storage Notes
-
Contains alkaline ingredients (potassium hydroxide); wear gloves, goggles, and use in well-ventilated spaces .
-
Shelf-stable for years—both the concentrate and diluted solution remain usable when stored properly
