Pinhole Cameras

The other assignment that was given to us was using pinhole cameras. Pinhole cameras are really interesting because they act like cameras however they don't function like one. To use the pinhole cameras, you simply place the "camera", which is basically a can with a very small hole on it, on a stable surface and leave it facing towards your subject for a few minutes. I was very familiar with pinhole cameras since we used them in my old school once therefore this wasn't such a difficult task for me.

An example of pinhole camera used.

The pinhole cameras are really easy to use however there are 2 things to keep in mind when using these; never have the pinhole facing towards the sun and the amount of time depends on how long you leave the camera out. When you have low light, you want to leave it out longer and vice versa however pinhole cameras don't normally take too long. Movement is also critical in using the pinhole cameras because if there is any movement, then it will turn out blurry. For example the turtles in my photo especially the one on the far right because before the turtle wasn't there but then halfway through, it moved into that position and stayed still which the pinhole caught. In the end, only the head of the turtle is shown because of how it moved.

The way that pinhole camera works it that light rays hits the subject and then reflects through the small hole, forming an inverted image on the film. Although, since the pinhole is very small, the film takes a longer time to be exposed. So why use one of these? Because they are made out of recycled cans, easy to make if you are handy with tools and almost similar to using an analog camera with similar rules applied.
