In Further (What you're doing now) and higher education you need to step-up your research and start to source higher quality research sources.
Probably the best research you can probably do is to actually work with or talk with the actual photographers themselves for extended periods of time. If you can assist a photographer, observe what the do and work with them as an assistant, that is valuable experience, where you'll learn an awful lot.
Another good research experience is to visit galleries and see the work first hand in exhibitons. This allows you to see the work; see how big it is, the quality of the photography, attention to detail, the texture and finish of the image, how it's mounted and presented. The galleries will also have up todate and useful information about the work alongside the work.
The best secondary research sources
The best secondary research sources are almost certainly hard copy sources such as books and journals. I would say the best by a long way are Journals such as...
- The British Journal of Photography
- Hotshoe
- Aperture
These journals are on-line, but they do not have the complete articles and all of the images seen in the actual journals. They're still definitely worth looking at.
