Creating Quality Digital Images for Your Presentations

Abstract

Many people attending this conference have advanced computer skills, but they may lack
digital camera knowledge because a different set of jargon describes camera functions. Materials
presented in this session will give attendees information about selecting digital cameras and
mastering their features to take images which will enhance and underscore information in
presentations such as PowerPoint. The focus will be on digital camera basics and on good
photographic composition.

Description

The digital camera mechanics portion of the presentation will address the relationship
between megapixels, image size and requirements for printing or screen viewing of images taken
digitally. This part will also compare media storage formats and battery types. Additionally, the
presentation will explain differences between optical and digital zoom lenses and reasons for
setting different values for the camera's sensitivity to light.
Attendees will learn the basics of how a camera works how the shutter and aperture
work together to control the amount of light which enters the camera and, in turn, creates the
image on a part of the camera, the charge coupled device, commonly called the CCD. An
overview of the functions found on most mid-price cameras will lead into a discussion of actually
taking and storing digital photos for long-term use.

The photographic composition portion will feature information on good composition,
depth of field and its role in composition, lighting of subjects, and close-up photography, which is
used to copy items such as manuscripts. The discussion of subject lighting will include an
explanation of natural lighting as well as techniques for using flash effectively. In addition, the
presentation will touch on techniques for photographing such subjects as people, moving objects,
architecture, and nature.

The presentation will be useful to people who are contemplating buying a digital camera
and to those who already own a digital camera but do not know how to use the various functions
effectively. At the end attendees should have a better grasp of how to create the images they want
for a variety of purposes, including images which will attract viewer attention and lead to better
understanding of material presented in lectures.
