Using cameras to create images and videos can improve most academic projects, like presentations, event promotion, project documentation. This page outlines the basics to using a camera and the projects associtaed with them and describe the resources available to acheive those projects.Media Loan has a range of analog and digital cameras, the Digital imaging studio (DIS) for digital photography, The mulitmedia Lab (MML) for media including video editing Black and white darkroom to develope your own film, Media loan also facilitates the developement of color film and purchase of film. Cameras have conceptually remained the same since their invention. their is a sensitive material, wehter it be analog film or a digiral imager. that material lives in a light tight container, a lense to collect the light, and 3 exposure controls. The best way to get into digital photography or video would be a DSLR like the Canon Rebel T6i. on the other hand, for film cameras, a 35mm camera is a good starting point, Media Loan has a vairiet like the Pentax K1000. By understanting exposure and lenses, you will be ready for most projects. THerea are also many accesories that attach to most cameras 1/8" jack on the bottom like a tripod, shoe on the top like a microphone or flash, lense to switch out, and cables that can either get a video feed, or external trigger for taking pictures.

Exposure

Exposuring photos correctly is crucial. Over exposed and is too white, while undersexposed is too dark. There are 3 controls on your camera used to affect how much exposure your image has. They are called ISO, Aperature, and Shutter speed and effect the exposure via sensitivity of image material, volume of light let in, and time for exposure respectivitly. each of these elements has a side effect, ISO adds noise when sensitivity is increased, Aperature increase the depth of field which is like how much wide the focus is, and a slower Shutter speed increases the exposure but also resulting in more motion blur. There is no perfect setting, you need to adjust your settings based off of what kind of lighting you are in, and what kind of effects you want. you may want motion blur, or a narrow depth of field. each element is outlinded below then explians how to balance them. these 3 elements are often described as the exposure triangle. A good way to get familiar with these concepts can be to play with either an Exposure Simulator by Anderson Images or another Exposure Simulator by Canon

  • recap on why it is useful
Exposure Element Other/Related Names Exposure Method Effect Unit Higher number means...
ISO Film Speed Sensitivity of Image Material Grain for Analog, Pixel Noise for Digital ISO of 400 More exposure, more noise
Aperture Iris Size of opening Depth of field f-stop of f/2.8 More exposure, less Depth of field,
Shutter Speed Shutter Time of exposure Motion Blur Shutter of 250 (which refers to 1/125 of a second) Less exposure, less blur
