Photographic black-and-white film Ilford Delta 100, ISO 100, sheet or roll format unspecified

Ilford Delta 100 is a black-and-white photographic film with ISO 100 sensitivity, engineered for fine-grain imaging and moderate contrast. Using ILFORD’s core-shell crystal technology in a traditional silver‑halide emulsion, this film delivers high sharpness and precise rendition suitable for studio, landscape and portrait work. It is compatible with standard darkroom processing and scanning workflows and can be exposed at ISO 100 for optimal results or pushed/pulled moderately between ISO 50 and ISO 200 depending on creative needs.

Advantages

Ilford Delta 100 offers exceptionally fine grain and a high level of acutance that preserves detail even in complex tones. The emulsion’s design reduces visible grain while maintaining reliable tonal separation and moderate contrast. Its stable response at the recommended ISO and tolerance for slight rating adjustments make it versatile for controlled lighting and long-exposure situations. The film’s characteristics support both traditional enlargement and high-resolution scanning.

Suitable for

• Studio portraiture with controlled lighting
• Landscape photography where fine detail is required
• Architectural and product photography demanding high sharpness
• Darkroom printing and high-resolution scanning workflows

Key specifications

• Black-and-white silver‑halide emulsion with core-shell crystal technology
• ISO sensitivity: 100 (recommended)
• Fine grain and high acutance for detailed image rendition
• Moderate contrast suitable for wide tonal separation
• Available in 35mm, 120 roll and sheet film formats

How to use

Expose the film at ISO 100 for nominal performance; for different creative effects or exposure constraints it can be rated between ISO 50 and ISO 200 with appropriate development adjustments. Process the film using standard black-and-white developing chemistry and times adjusted to developer type and desired contrast. After processing, dry, inspect and, if needed, scan at high resolution or make darkroom enlargements following normal handling and archival procedures.

Usage recommendations

For optimal sharpness and lowest visible grain, maintain accurate metering and stable development times. When scanning, use high-resolution settings and appropriate sharpening workflows to preserve the film’s fine detail. For push or pull processing, consult developer data sheets to modify times and temperature to achieve consistent results.
