Camera Skills

In this next experiment I studied the camera and experimented with the different types of exposure it has the offer. In this experiment I used the SONY Z5 and the Cannon 550D. Studying and using the various types of cameras has helped me gain vital knowledge that will help me in future lessons.

Iris/Aperture

One of the first skills I learned involved the iris/Aperture. This is a mechanical opening that allows the user to control the amount of light that passes through and out of the camera. When the opening is large, a lot of light can pass through making the image bright. When the opening is small, less light passes though making the image dark. When I experimented with this, I noticed the depth of field can be effected. However this may be useful for my music video as it has a stylistic effect. The aperture ranges from 1.8 a large whole that yet more light in and 32 that yet less light in.

Shutter Speed

Next I was shown how shutter speed works. This basically describes how much time the light sensitive chip is exposed to light for. If the chip is exposed to light for a short period of time the image will be darker. If the chip is exposed for a long amount of time it will be lighter. During this experiment of shutter speed I wanted a clearer image, to perform this I used a short exposure. if I had used a long exposure the image would be less clear than the short which looks unprofessional. The shutter speed ranges from 25-50. 25 refers to the long time and 50 refers to the short.

Gain/Film speed

Next I learned how to use gain in a video, and film speed in a camera. The gain males the camera increase the sensitivity, this results in a brighter image in the video camera. The film speed in a camera is very similar however it is measured differently using ISO. I also find that the lowest setting works best. If it is higher the image becomes noisy.
