Profile notes
Ilford Delta 100 Professional is a fine-grain, medium-speed black-and-white film from HARMAN Technology's Delta series — Ilford's family of tabular-grain (T-grain) emulsions developed to compete with Kodak T-Max. Rated ISO 100/21°, Delta 100 excels in controlled lighting conditions where maximum resolution and micro-contrast are priorities. Its tabular grain structure delivers a measurably finer grain than conventional cubic-grain films at equivalent speeds, with exceptional edge definition and a smooth tonal scale from deep shadows to bright highlights. The film responds well to pull processing (EI 50) for even finer grain and to push to EI 200 with modest quality impact. Delta 100 can be processed in all standard B&W developers including Ilford ID-11, ILFOTEC DD-X, and Kodak D-76. Available in 35mm (36 exp), 120, and sheet film formats.
