Mastering Rodinal Development

Rodinal remains a favorite among film photographers for its unique ability to produce high contrast and fine grain. Understanding the dilution ratios and development times is essential for achieving the desired look.

Dilution Ratios and Effects

• 1:50 dilution produces fine grain and high sharpness for 35mm formats.
• 1:100 dilution increases contrast and speed, ideal for enlargements.
• 1:150 dilution is best for very fine grain in high ISO films like Tri-X.

Development Time Variations

• Standard development times yield predictable results for fresh stock.
• Stand development extends life and reduces grain significantly.
• Agitation speed must remain consistent for repeatable results.

The final image depends on these specific choices regarding chemical strength and timing.
