OK, I’ve got the picture in the camera - now what?

 

Digital photography has come of age. It is appearing everywhere—you find digital cameras on key rings, in wireless phones, and of course, all shapes and sizes of more traditional cameras. With the image in a digital form, it becomes much easier to share images, whether via printing, e-mail, or posting on the web.

But just taking the picture and distributing it has some issues. You need to know how to process the image so that it is appropriate for your intended viewer. Have you ever received an image in an e-mail, only to find that you can only view about one quarter of the image? Have you ever waited for 10 minutes on a dial-up connection just to get one image? Have you ever seen a really distorted image on the web? Each target delivery mechanism has its pros and cons, and if you don’t adjust your image appropriately, you may end up with a less than optimum viewing situation.

At the next DACS General Meeting, our own Random Access wizard, Bruce Preston, will address the basics of digital photography and image processing. For his presentation, Bruce will discuss digital images in general: the file formats and conventions; what is involved in editing an image; cropping, resizing and compressing it; and evaluating the trade-offs between image size and quality. Several different image editing programs will be used, but the emphasis will be on the basic principles involved rather than on how a particular program works. As time permits, other editing processes such as color correction (white balance, etc.,) red-eye correction, etc. will also be discussed.

The DACS General Meeting begins at 7 p.m. with Random Access, followed by a brief business session and a break for networking. The presentation starts at 8 p.m. All General meetings are open to the public.
