Question

Suppose you have two pinhole cameras. The first has a small round hole in the front. The second is identical except it has a square hole of the same area as the round hole in the first camera. Would the pictures taken by these two cameras, under the same conditions, be different in any obvious way? Explain.

Short answer

No, they will not be significantly different.

Step-by-step solution

Uses of pinhole photography

Pinhole photography is frequently used to capture the sun's movement over time. Because pinhole cameras are difficult to detect, they are sometimes used for surveillance.

step 2:pinholes definition

Pinholes are, by definition, so small that their dimensions are rarely important. There may be minor differences in image quality, but the overall tendency of image formation will be the same regardless of the shape of the pinhole.
