| Subject Size (o) × Ratio (m) | mSize of the subject (o) including margins (m)... (1) |
| Field of View (a) | degreesField of view in (1)... (2) |
| Focal Length (f2) | mmFocal length calculated from (2) |
| Viewing Angle (a3) | degreesField of view of (f1) |
| Subject Size (o2) | mSubject size calculated from the focal length (f1) and the distance to the subject (d) |
| Subject Distance (d2) | mDistance to the subject calculated from the focal length (f1), the subject’s size (o), and the magnification ratio (m) |
Although the margins in the figure are shown on the left and right, enter the total percentage into the “Margin (m)” field.
