Pinhole Investigation
A pinhole camera is a camera that has no lens, but instead,contains a small, pinhole sized aperture. This idea was introduced by an Arabic scientist, Ibn al-Haytham in 1,000 AD. He described the “camera obscura” effect caused by the pin-sized hole in a camera. The first known use of the camera obscura (pinhole camera) was in 1544, by an astronomer named Gemma Frisius in a dark room. This continued to be experimented with in the 1800s by inventors such as David Brewstesr, William Crookes, Thomas Edison, etc. The small aperture of the pinhole camera is often used for solargraphy. To track the movement of the sun, or to safely capture an image of a solar eclipse. One caveat about the pinhole camera, is that it often captures images upside down, and can vary in clarity. However, one benefit is that since there is no lens, there is no need for focusing the image, and there are no visual side effects such as color distortion or noise in the picture.

Ted Talk
The speaker shows famous photographs from history. He explains that photographs capture exact moments and memories in time. Everyone has the ability to take one or two good photographs. But great photographers can capture many, and are able to paint a narrative through their pictures. Only photographers can take pictures that tell a story. The speaker uses an example of pictures of hunted elephants to show how a photographer can use their photos to inflict emotion onto viewers. Pictures from the ocean show the impacts of overfishing.
Photography also allows the opportunity to speak out against social conflicts. Photography humanizes subjects, in ways that articles and writing cannot. The photojournalism process also allows for an interesting experience and story for the artist. Photojournalism allows people to see and face real issues troubling our world today. The main issue the speaker focuses on and uses photography to convey is animal abuse. We see this through the pictures of poachers taking ivory, and photos of sea animals being trapped and killed.
If I were to critique this speech, I would say that the speaker needs to focus more on the message he wishes to convey. He focuses too much on the examples of photos he/his team have taken, when he should be explaining more how photography connects us. When he shows the pictures he should focus less on the subject matter, and explain how the photos support his claim. Furthermore, he strayed away from his topic too much. His words lacked much substance.
