The test I am about to describe is a simple test. In a nutshell, it consists of the following: We take a picture of a test object containing typical camera picture subject matter. This subject matter is arranged in a test pattern, and the pattern is repeated over the entire test object. We then make a black-and-white enlargement of the picture and visually compare the picture sharpness over the format with a graded standard. The standard contains a series of pictures of the same pattern that is repeated over the test object, and the range of sharpness of the series extends from excellent to poor. In developing the test, our goal was to satisfy the following basic objectives.
