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).

How does a pinhole camera work to capture images without the use of a lens?
A pinhole camera works by allowing light to pass through a small hole (the pinhole) and onto a light-sensitive surface inside the camera. The pinhole acts like a lens, focusing the light to create an image. The image is then captured on the surface, such as film or a digital sensor, without the need for a traditional lens.
Image formed by a pinhole camera?
Pin holiday camera light travels in straight lines
What are the key components needed to create a pinhole camera film?
To create a pinhole camera film, you will need a light-tight container, a piece of photographic film or light-sensitive paper, and a small pinhole to let light in. The container should be able to hold the film securely and prevent light from entering except through the pinhole.
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.
What is the optimal size for a pinhole in order to achieve the best results in a pinhole camera?
The optimal size for a pinhole in a pinhole camera is typically around 0.5mm to 0.3mm in diameter. This size allows for sharper images and better light exposure without causing excessive blurring.
How does a pinhole camera work to capture images?
A pinhole camera works by allowing light to pass through a small hole (the pinhole) and project an inverted image onto a surface inside the camera. The image is then captured by the surface, such as film or a digital sensor, creating a photograph.
Is the image on the screen of a pinhole camera back to front?
Yes, the image on the screen of a pinhole camera is upside down because of the way light passes through the small aperture and projects onto the film or sensor inside the camera. It is a characteristic of pinhole cameras due to the nature of how light travels through a small hole.
What is pinhole camera used for?
it is used to prove the fact that light is rectilinear in motion
