Based on some curiosity research, I found out that the Pinhole Camera is used in solargraphy to observe the sun's movement in the sky and in viewing eclipses. However, there are several disadvantages to Pinhole Camera, where the image is inverted, faint, and it cannot form an image of a moving object.

The different variables that play into a pinhole camera are actually the size of the hole. It can actually affect the sharpness and brightness of the image. One of the benefits of a pinhole camera is that it displays sharp images with a longer exposure time and its strength in capturing images in low light. Pinhole cameras are actually used by artists to create unique and creative images.

How does the size of the pinhole affect the image produced on the wall? I would imagine that increasing the size of the pinhole would result in a brighter but blurrier image, since more light is allowed in, but from conflicting angles and positions at each point in the wall. How does this relate to modifying the different properties of a lens? Does a larger pinhole = a larger aperture?
