explain pinhole camera?
Answers
Answer:
A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called 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.
How To Make a Pinhole Camera
You can make a simple pinhole camera with simple materials probably available at your own home. The step-wise procedure has been described below.
Take a small box like a shoe-box or a coffee can
Paint the box entirely in black to light-proof it
Appropriately determine the distance between the film and light source and make your circular pinhole on the bottom of the box
Make a shutter by cutting a piece of thick black chart paper (2 x 2 inches ideal)
Use sturdy duct tape to hold the shutter in place
Use a light adhesive to control shutter flap and light entering the box
Make a viewfinder out of cardboard
