Photography is to do with light forming an image, normally by means of a lens. The image is then permanently recorded by:
- chemical means, using film, liquid chemicals and darkroom processes
Chemical forms of image recording are long established, steadily improved since the mid 19th century
or
- digital means, using an electronic sensor, data storage and processing, and print-out via a computer.
Digital methods have only become practical after year 2005 but are rapidly evolving. Photographers increasingly combine the two — shooting on Film and then transferring results into digital form for manipulating and print-out.
You don’t need to understand either chemistry or electronics to take good photographs of course, but it is important to have sufficient practical skills to control results and so work with confidence.
Fundamental of photography: picture structuring, lights, intensity, distance, focusing, exposure, printing
