## Definition

to develop a film or digital image in a way that makes it look dark or unclear. This usually happens when the chemicals or the light are not strong enough.

For teachers: to develop a photographic film or digital image in a manner that results in a lack of detail or a dark appearance. Often used to describe the failure of the development process to produce a clear, properly exposed image.

## Examples

- The photo turned out underdeveloped because the film was old.
- The photographer realized the negatives were underdeveloped after comparing them to the original digital files.
- The underdeveloped negatives suggested that the lab had used a lower concentration of chemicals than recommended, resulting in a loss of fine detail in the shadows.
