ABSTRACT
Having composed and formed the picture in the camera the next step is to make the image
permanent. Digital image capture is increasingly used, recording images as electronic signals
from a CCD panel (Chapter 6), but a huge amount of photography relies on chemically coated
film as the image-recording medium because of its fine quality of results and lower equipment
costs. Once film is exposed and processed it can be printed onto chemically coated papers or
electronically scanned (Chapter 14), allowing more adjustments to be made to pictures than ever
before.
