Technology has made it easier than ever for you to make bad photographs. –John DunkerPhotographs are good for showing readers what something looks like, but are not good for pointing out details (use a technical illustration instead).

Photographs must be screened (converted into a dot pattern) before they can be reproduced. Photographs do not photocopy well, even when screened. Photographs can be either manually pasted into the manual, or a graphics file of the photograph can be incorporated into your word processing file.
