A suggestion for Making the Transition from Film to Digital.
On page 4 use 5 circles of different diameters to illustrate the table that shows the number of levels. This way folks can see that the outermost circle has the most area and the innermost circle the least. The circle area increases or decreases as the square of the radius. You could even shade the circles with 20% steps from white to black.
Remember when f stops were actually plates with different sized holes? I don't think we are that old but sometimes we feel that old.
A couple of other suggestions but then the piece could grow to twice its size easily or become too technical.
1. For RAW vs JPEG - when shooting sports or action scenes you can underexpose the scene for a faster shutter speed but recover more image with RAW. At the same time you can't shoot as many images continuously.
2. I have found that most programs like Thumbs Plus, Bibble, ACDSee, do an adequate job of converting RAW to JPEG with their default settings so bulk converting RAW to JPEG isn't an issue. Therefore there really isn't the need for RAW plus JPEG even when shooting casual scenes.
3. If one shoots 3 JPEG images to bracket the exposure, they have used almost as much storage space as 1 RAW image and still have a fraction of the information.
