Arista EDU Ultra 100 B&W Negative Film 4x5" 50

This is a traditional black and white negative film rated at 100 ISO. It comes in a 4x5 inch sheet format with 50 sheets per pack. The film is designed for processing in standard black and white chemicals and suits photographers working with large format cameras.

Suited for large format shooters who develop

Photographers needing roll film sizes such as 35mm or 120 should look at other variants. The sheet format requires compatible film holders and a darkroom or changing bag for loading. Buyers who want colour film or a higher speed emulsion will need a different product.

100 ISO speed rating determines exposure latitude

The fixed sensitivity of 100 ISO suits controlled lighting and tripod work. It offers fine grain but requires longer exposures than faster films. Developers such as Arista 76 Powder or Kodak D-76 are listed with times at 68 degrees Fahrenheit. Match your chemistry and workflow to these specifications.

Questions about this item

How do I load the 4x5 inch sheets into a film holder without scratching the emulsion?

Work in total darkness. Hold each sheet by the edges, identify the notched corner to confirm emulsion side faces the lens, slide it firmly into the holder grooves until it seats, then close the dark slide before turning on lights.

When will the 50-sheet box need to be replaced if I shoot ten sheets per month?

At ten sheets a month the box lasts five months. Unexposed sheets keep for years when stored cool and dry; once exposed, develop promptly to avoid latent-image fade.

What is the first limit I hit when pushing development times beyond the listed 6–10 minute ranges at 20 °C?

Extended development raises base fog and grain before any speed gain appears, so the practical limit is the longest recommended time for your chosen developer and dilution.
