What is the effect of all types of fog on the radiographic image?

Explanation:
Fog adds unwanted exposure that creates a uniform veil over the radiograph. This extra density makes all areas look similarly gray, which reduces the differences between tissues that should appear distinct. Because image contrast depends on those differences, fog lowers contrast and makes details harder to separate. It isn’t about increasing latitude or directly increasing patient dose—the main effect is the drop in image contrast due to the added, non-tissue-related exposure.
