Can I presume that:• you understand the value of using

images on-line in your teaching• that you are ‘quality conscious’• that you are aware that raw images

generally need ‘post-production’- manipulation with a computer- to look and work their best

• that you want to better understand how that works….?

• Digital photography is about dots(how many, where they are, how bright, what colour)

• Digital imaging is the manipulation of the dots (to alter, repair, to create new art) after the acquisition stage.

This is key: When we consider images for inclusion in electronic presentations and delivery systems, we need to consider resolution and pixel dimensions…and forget about the more familiar “linear measurements”.

e.g. 400 x 600 pixels x 72dpi, rather than

4 x 6 inches

Let’s look (briefly) at a few examples.In all cases, I’ll lead with the raw image (sized for this presentation, of course), and follow with the final manipulated image.Note and discuss any differences or improvements.

a bit about file formatsa bit about file formats

Once you begin to work with digital images, you have to learn a bit about the file formats.

• Most cameras allow you to select between several formats. The .jpg format is accepted as the standard for general use, although it’s far from perfect…

• Once you begin to edit photographs, you’ll want to know a few more.

Unless you have a good reason not to, you should plan to shoot at high resolutions and low compression. Otherwise, you may regret it when you take the once-in-a-lifetime shot.

Stage 2- here’s what I’d like to do:

• Photograph a volunteer or product• Open the resulting image in Photoshop• Make some basic image ‘improvements’• Save the file in a variety of formats• Integrate those images into a web page• Show some examples of how Photoshop

can be used to develop complex composite images and websites.
