How Hard do you Think it is to Convince Somone to Stop Smoking?

If you have ever wanted to present a pictorial image to a possible client that would help you get a difficult message across, picture yourself trying to convince a middle-aged man to quit smoking if all you had to communicate with were images (no words or data).

In this tutorial lab, we spend some time learning Photoshop and how to use it to operate on already digitized images to make them carry a special message. Anna Petkov cleaned up a digitized photo of the skull in the St. Olaf anatomy lab (picture by Tom Dressen) so the hinges and dissection saw cuts vanished, emphasized the suture loines, and then added the cirarette and wafting yellowish smoke to make her point about smoking. This image probably is worth a thousand words.

As a testimony to the effectiveness of imagry, this particular photo has been "stolen" from bulletin boards more than any others I have posted in the past few years.

Learning how to add artistic information to a core image is one way augment verbal communication. Another is shown below.

How Hard do you Think it is to Convince Somone to Have a Colonoscopy Every 3 Years?

In this image, a composite has been prepared that could be used to show a client why it is important to have a regular colonoscopy examination to locate precancerous polyps as one effective way of preventing colon cancer. Unfortunately, the "prep" for the procedure is onerous, and many people do not like the idea of the whole thing at all, even when it is clear to them that it is much less traumatic than what be needed to surgically correct for colon cancer itself. In this image, the colon illustration has been captured from A.D.A.M., and some digitized internal images showing the location of a precancerous polyp have been added, all using Phtoshop. No words are needed to communicate the importance of getting rid of that polyp before it becomes cancer. In this tutorial lab, we learn how to do this kind of composite image construction.
