Off axis light is light that is not behind us/same axis as the camera. All natural light is off axis.
The best way to see what light looks like is to stand where the light is coming from. There are 2 point of views. That of your camera and that of the light source (assuming it is off axis).
If you light cannot see it, it will not be well lit.
Start to learn to light without a meter:
Put your shutter speed at max sync speed. For me that is 1/320 on my Canon XTi
Aperture of f/5.6
Take a test shot. The subject is likely to be too dark or too light. Change your aperture until you get a correct exposure.
This is what gets me a little bit confused. From my understanding, say f/5.6 is the widest aperture that you can have with your lens. If the picture is too dark, wouldn't you want to open up your aperture even more; if f/5.6 is your widest aperture (or close to it) you wouldn't be able to open it up any more to let in more light. Will have to get the camera out for this one.
Mini assignment: Place your subject, obtain the correct exposure. Place your light and take a photo from the perspective of the light source, and the perspective of the camera (in front of the subject).

P.s. I really should be cleaning or doing something equally as productive instead of this but this is way more fun.
