WebA pinhole camera is a light-proof box with only a tiny hole in one side that has a small aperture but no lens. If light from an item passes through the aperture, it creates an inverted image on the other side of the box, that is known as the camera obscura effect. A pinhole camera is made using the camera obscura concept. http://www.phys.ufl.edu/~meisel/Pinhole-Physics-Lab1.pdf

A pinhole camera is a simple camera without a lens but with a tiny aperture, a pinhole – effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.

WebAs pinhole photographs have nearly infinite depth of field, everything appears in focus. As there's no lens distortion, wide-angle images remain absolutely rectilinear. Exposure times … WebUnlike a lens, a pinhole or other small opening can focus light coming from any distance. Because it's such a small opening, it only allows light to come through in one place, and thus in only one direction from any particular source. So there's no blur and everything is in focus.

WebOct 19, 2011 · 5. There are a couple of concepts that you really need to understand to grasp depth of field. First, lenses focus on a plane. You can envisage this as, basically, a razor thin slice of reality and everything in that slice will be perfectly in focus. Everything in front, or behind, will not be. Second, there is a range out of the focal plane ...
