Accommodation in Eye and Camera
Accommodation is the process of adjusting the focus distance of an optical instrument to the object which is to be viewed. This process is done very differently by the eye and a camera.
|
Accommodation from distant to close objects for the eye is done by rounding out the lens to shorten its focal length, since the image distance to the retina is essentially fixed. |
Accommodation from distant to close objects for the camera is done by moving the lens further from the film since the focal length is fixed. |
