Adox Adonal Developer is a highly concentrated fine-grain, one-shot black and white film developer. By diluting it according to requirements, you can match Adonal to any black and white negative film regardless of contrast. Grain is also a factor that will be influenced by the dilution. 1+100 will produce the finest grain while 1+25 will produce a noticeably pronounced grain pattern.
Note:
You are advised to wear rubber gloves and taking normal darkroom precautions when handling this product
Shelf life is several years (half-opened bottles reported to last over 40 years)
Recommended dilution: 1+50 for general purpose work
The solution is light straw colored when first opened, and during the course of a year turns darker until eventually becoming deep purple-brown - but the developer will perform regardless of color
