Want this question answered?
Any object that blocks the light forms a shadow.
Shadows can only form when there is light present. A shadow is the result of a solid object blocking visible light. As a mirror is a solid object it can indeed produce a shadow, but nothing can form a shadow in the dark, there must first exist a light source.
This is data from a camera in it's raw form and it also contains no process data from the image sensor or digital camera , image scanner nor modified by a camera ad-on software.
Yes, yes it does.
because light passes through, and you cant have a shadow with light on now can you?
From the absence of light. Shadow is form from an opaque or translucent object blocking a light source (since light travels in a straight line).
farther then f from the lens
Any object that blocks the light forms a shadow.
A source of light and an opaque object.
A focusing screen in a pinhole camera? Uhh...no. A pinhole camera is a box with a very small hole in one end of it and a piece of film in the other end. The screens in reflex cameras and in view cameras are translucent to give the image something to form on. The light will pass through a transparent screen without forming an image, and it won't go through an opaque screen at all.
The function of lens is to to form an image of an object by converging or diverging rays of light from the object.
