Technical Knowledge And Understanding
Gbogbo ọrọ náà
The specification calls light the most important element in photography, and it means that literally. There is no photograph without it, the word itself means drawing with light, and every piece of equipment in the subject exists to measure light, admit a controlled quantity of it, record it, or convert that record into something you can look at. Understanding the apparatus is what turns a lucky frame into a repeatable result.
This is the technical companion to the formal elements topic. Where that one asks what the picture says, this one asks how the machine and the chemistry deliver it: the quality, direction and colour of light, metering and the stop as a unit of measurement, exposure and the histogram, studio lighting, the darkroom from emulsion to fixer and the paper grades and test strips that go with it, and image manipulation by both silver-based and digital means, through to output.
Ebumnobi

- Understand viewpoints, composition and depth of field
- Understand darkroom techniques involving the recognition of appropriate paper types, developing and printing, emulsions, exposures, tone and contrast
- Understand manipulation of the image, either silver-based technology or digital format, through electronic and mechanical means including lasers, computers, scanners and photocopiers
