I'd assume you'd need to know the methods of these:
- Black and White Photography
- Colour Photography
- Digital Photography
Each of these genres of photography require a different methods, it could be using a dark room, poloroid productions, digital manipulation through the use of computers etc. etc.
I don't actually know these methods, as photography wasn't a medium I considered in my study. I would ask your teacher whether it would be suitable for you to write on, on the end of year exam. Examiners know the ins and outs of all mediums used, and if you don't know them in
complete detail, the examiners won't give you full marks.
This year I used Oil Paint as my medium, and I know the process and methods in depth as to how to develop pieces, starting from the construction of the frames that hold the canvas material. You need to cover
all steps in creating a photograph, including the anatomy of the camera used and how to process the image dependant on that camera.
