The image is a table titled "Tabella per la determinazione dell'esatta esposizione" which translates to "Table for the determination of the espositions" in English. The table is divided into two columns, with the first column listing the focal length of a camera lens and the second column showing the number of focal lengths.

The first column lists the focal lengths of the camera lens, ranging from 90 mm to 120 mm. The second column shows the focal width of the lens. The focal length ranges from 180 mm to 180 mm, with each focal length having a different focal length. The first column shows that the lens has a focal length range of 120 mm, while the last column shows how the lens can be adjusted to fit different sizes. The third column shows where the lens should be adjusted, and the fourth column shows whether the lens is suitable for a wide-angle lens or a wide angle lens. 

At the bottom of the table, there is a note that reads "Focal 300 mm, Focal 360 mm, focal 420 mm, and focal 480 mm." This indicates that the table is used to measure the focal distance between the two lenses.
