Learn focusing the lens of photogrammetric camera for better output

One consideration for normal photography is, of course, focusing the lens of photogrammetric camera so the image is sharp. The range of acceptable sharpness is called the depth of focus. The depth of focus of a lens is a function of many factors, including: the focal length of the lens, the format size, the distance from the camera to the object, the size of the object, and the f-number of the lens. As you can appreciate from all the factors listed above, the depth of focus of photogrammetric camera can be a complex function.
