Motion Tracking is necessary when we want stuff like graphics to look like they are on the scene with video that we shot. To make this happen, we use 3D tracking tools like PF Hoe to track the shot. This data is then imported into Motion. From there, we can add 3D elements to the scene that will follow the camera motion of the live action camera.

In today’s show I review the Personal Computer Museum Web Site (pcmuseum.ca).

My remarks today center around typography:
• Wide columns of text are hard on the eye.
• Increase your text readability with nice wide margins.
• Leading can also help make big blocks of text easier on the eye.
• Centering blocks of text – just say no!
• Consider using columns.
• On the Web, underlining usually indicates links, so it’s best not to use underlining for anything else.

The demo will consist of the following points:

An explanation of the spectrum of electromagnetic radiation. (Slide showing the spectrum) If I can find a prism and light source I can do this in a more organic way.

A slide explaining that the human eye only has three kinds of color receptors (cones).

A slide showing the response of these cones. I will note that the response of each type of cone overlaps the others. I can draw these on a white board if you like.

A color illusion slide that shows that the same stimulus surrounded by different colors does not look the same to the human eye. This is the yellow blue slide I demoed at the last shoot. I can make prints and hold them up rather than use Power Point.

I will bring a fresh banana and explain that it absorbs all wavelengths of light except yellow. It reflects the yellow wavelength.

I will explain that if you look closely at your TV screen you will see only red and green pixels. I will have a print I can hold up showing a macro photo of a TV screen. The yellow you see is an illusion in your brain.

A slide showing what happens when you stimulate the Red and Blue cones. You see magenta. Note that magenta does not show up in the spectrum. You cannot create magenta using a single wavelength. It is an illusion that only takes place in the brain when two spectral frequencies enter the eye.

Compare how the ear can easily tell the difference between one signal audio frequency and two. I can bring a small keyboard or use Garage Band to demo this. Note that because of how the eye is made it cannot do this. It creates an illusion of one color when two spectral frequencies are used as stimulus.

If you are a digital graphic artist or photographer be sure your school or books you buy have a section on basic color theory. It is the foundation of knowing how to manufacture and distribute color.
