A radiographic film with wide latitude is characterized by low contrast. Wide latitude means that the film can effectively capture varying levels of exposure, enabling it to respond well to a broader range of radiographic conditions.

When a film exhibits low contrast, it indicates that it can distinguish between smaller differences in density and exposure levels, which results in a more gradual transition between shades of black, white, and gray. This property is particularly beneficial in applications where detail and subtle variations in material thickness are critical for accurate interpretation. For instance, when inspecting welds or thicker components, low contrast may help in identifying flaws or inconsistencies without losing important information.

In comparison, films with high contrast tend to produce stark differences between light and dark areas, which can obscure details in certain applications. Thus, the relationship between wide latitude and low contrast is fundamental in radiographic testing, allowing for a more forgiving evaluation of various parts or materials.
