I believe you are talking about minimum focusing distance.
If your subjet is too close to the camera, then the lens may not be able to completel focus on it.
Diferent lenses have different focal lenghts.
Some Wide angle lens can work at 20 to 25 inches, while some larger zoom lenses need more than 3 feet of minimum focusing distance...
If you are using a compact camera, then you could try using the macro mode to work really close to the subject you are trying to shoot.
You can figure out why an image in a pinhole camera is upside down if you think about how the light travels to get to the image. Light from an object higher (or the top of the object) than the camera travels in a straight line down to the camera. It goes through the pinhole and continues heading down until it hits the back of the camera. This means that the image of something higher than the camera is now low in the image. The opposite is true for light from an object lower than the camera (or the bottom of the object): it travels to a point higher in the image. Still does answer my question, how did the image get upside down? answer was no concusive.
when an object is brought closer to the lens of a camera it gets smaller so that we could capture it properly. such lenses in a camera are conclave.
the image distance will appear the same

the part of an image closest to the camera
When you take a photograph of an object, light from the object travels to the camera and is refracted by the lens, forming an image on the film. The image on the film is a real image because light rays actually meet there. The image is smaller than the object, because the object is a lot further away than the focal length of the lens and the image is inverted but the camera flips the image so that we see it the right way up.

The image is inverted and smaller than the object.
If the object distance is decreased in a pin hole camera, the image size will increase. If the object is too close, the full image will not be formed and the screen will appear dark.

Take a picture with your camera phone then mail it to your internet mail box.
A camera lucida device is used by artists as a drawing aid. A camera lucida is used to superimpose the image of an object onto a drawing surface so the artist can recreate the image.
nope. bcoz the image is formed behind the mirror.
the part of the camera where the image object is formed
concave mirrors
