How did camera obscura lead to photography?

Then, in 1816, Joseph Niepce began creating what many believe to be the world’s first photographs. He used a camera obscura to expose paper covered in silver chloride to light. The resulting images were blurry and they faded quickly, lasting only a day at the most.

Similarly, the light from the bottom of the candle appears projected at the top of the wall inside the box, making the image appear upside down.

How does the size of the hole in a pinhole camera effect the image?

Up to a certain point, the smaller the hole, the sharper the image, but the dimmer the projected image. Optimally, the size of the aperture should be 1/100 or less of the distance between it and the projected image.

Because the front part of the eye is curved, it bends the light, creating an upside down image on the retina. The brain eventually turns the image the right way up. They are sensitive to light but not to colour. In darkness, the cones do not function at all.
