Which type of film quality issue arises when humidity is too high?

When humidity levels are too high, films can absorb excess moisture from the air. This moisture can lead to films becoming sticky, making them difficult to handle. The increased stickiness can cause films to stick together, which complicates processing and can potentially damage the film surface when attempting to separate them. Adequate humidity control is essential in film storage and handling to ensure optimal quality and prevent this issue.

In contrast, other issues related to humidity, such as increased static marks, are more typically associated with low humidity levels. Faster film processing is generally not a direct result of high humidity, and while increased humidity may impact image quality, it does not inherently result in lower image contrast. Thus, the challenge of sticky films directly correlates to high humidity and highlights the importance of maintaining proper environmental conditions for film storage and handling.
