Pinhole camera in physics – What does exposure time and depth of field mean?
If you have a pinhole camera with a large hole = short exposure time, blurry image
Pinhole camera with small hole = sharp image and long exposure time
Modern cameras solve this problem with lenses that focus a light beam on a very specific point -> but then you have a problem with the depth of field.
I basically understand the pinhole camera, but I don't understand these two terms…

Exposure time: How long to drop the light on the sensor (for example 1 second)
Deep focus: How large is the area that is sharply mapped. The larger the aperture, the smaller the sharp region.
Like normal cameras. It's probably similar to a hole camera.
In the hole camera, the sharpness is independent of the distance.
