What type of image quality does finer grain film provide?

Finer grain film is designed to produce images with a higher level of detail due to its smaller silver grains. These smaller grains allow for more precise delineation of structures within the image, resulting in sharper and clearer images. As a result, finer grain films are capable of resolving more intricate features in the radiographic image, which is essential in applications where precise interpretation is critical. This characteristic is particularly valuable in applications such as weld inspections, where anomalies, such as cracks or voids, need to be identified distinctly to ensure the integrity of the material being examined. Higher resolution images enhance the ability to detect these details, making finer grain film an advantageous choice in radiographic testing.
