DI-13 By Phil Davis is a developer that's ideal for subjects from normal (7-stop) to extremely long (10+ stops) range when increased shadow contrast and reduced mid-tone contrast are desired. It has been formulated specifically to take advantage of the unique characteristics of Kodak T-Max 100 film and is not recommended for use with any other film material. DI-13 provides low to very low contrast with excellent shadow detail, while maintaining relatively high film speed. Not recommended for expansion development.
