A camera admits light through an opening to expose an image on film. To get a sharp image if the light is not bright, you need a large hole, but the larger the hole, the more blurred (unfocused) is the image. But if you make the hole as small as a pinhole (like poking a pin through cardboard), you will get a focused picture if the light outside is bright enough. If the hole is any larger than that, you need to put a lens in the hole to focus the light. The larger the hole, the dimmer is the scene that you can capture, but the larger the lens, the more complicated is the optics (the physical design of the glass lenses, using several lenses in a row).

∙ 12y agoThe pinhole camera is an early form of the camera. People use it nowadays just to see what is was like, and it can make a cool effect on your photo, but you have to do it right or it will be under/over exposed.

Image formed by a pinhole camera?
Pin holiday camera light travels in straight lines
What is the science toy concept of a pinhole camera?
A pinhole camera has special paper put inside of it, absorbing the light making lots of shadows ect.
What do the pinhole and film camera have in common?
A pinhole and a camera both determine how much light comes through to make a picture, if there isn't enough light in you photo . The photo wont show.
What can be done for a pinhole camera to take ordinary photographs?
pour oil on the camera and then light it with a match
Why the image formed on the screen of the pinhole camera is inverted?
The image formed on the screen of the pinhole camera is inverted because the aperture, which is a small hole, bends the light that enters the camera. This basically shows that light travels in straight line.
What is the principles on which a pinhole camera works?
Rectilinear propogation of light.
Why is the image formed by a pinhole inverted?
An inverted image is formed in a pinhole camera because the light rays coming from the top and the bottom of the object intersect at the pinhole.
What is pinhole camera used for?
it is used to prove the fact that light is rectilinear in motion
Conclusion for pinhole camera?
it is a camera which is very useful to us more than simple camera.
What is the superiority of pinhole camera?
The pinhole camera is simple and requires no complex lens-based optical systems to work effectively as an image maker. In its simplest form it is no more than a light-tight box with a pinhole on one end and a place for a sheet of light sensitive material on the other.
What camera came after the pinhole camera?
The daguerreotype.
Is a stereoscope related to a pinhole camera?
no stereoscope are the glasses we use while watching 3-d movies and pinhole camera shows the image of anything on the other side which is inverted and enlarged
