Black and White Film Ilford 1743399

Ilford Delta 100 Professional is a medium-speed black-and-white film rated ISO 100, designed to deliver exceptionally fine grain and high sharpness. Using core-shell crystal technology, the film provides precise image rendition and outstanding clarity of detail. It performs best at its recommended rating of ISO 100/21 and also yields excellent results when exposed between ISO 50 and ISO 200.

Advantages

The core-shell emulsion structure offers very fine grain combined with high acutance, producing clear edges and accurate tonal gradation. The film’s wide exposure latitude supports reliable performance across varied lighting conditions, while its ISO 100 sensitivity balances detail retention with low noise for high-quality enlargements and scans.

Suitable for

• Studio portrait photography where fine detail and smooth tonality are required
• Landscape and architectural photography needing high sharpness and clarity
• Fine art and black-and-white documentary work that benefits from precise image rendition
• Photographers seeking low-grain negatives for large prints or high-resolution scanning

How to use

Meter and expose at ISO 100 for best results, or adjust to ISO 50–200 depending on creative needs and development choice. Process the film using standard black-and-white developers and recommended times for neutral contrast, or alter development to control contrast and grain. Handle negatives carefully after processing to avoid scratches and store in archival sleeves.

Usage recommendations

For maximum sharpness and finest grain, expose at ISO 100 and use developers and times recommended by Ilford or standard reference charts. When pushing or pulling exposure, test small batches to determine preferred contrast and grain characteristics before large runs.
