Above: Angle of view of different lenses.

ABOVE: if I stand 20feet from my model using a 24mm lens designed for a full-frame camera the wide lens captures the entire shop front +signage

7. Crop factor

ABOVE: if I stand 20feet from my model using a 24mm lens designed for a full-frame camera the wide lens captures the entire shop front +signage. If I take that same lens and put it on a crop sensor camera, stand in the same spot the lens now captures less of the image. It crops out part of the frame.


The crop factor of different focal lengths and cameras.

8. Aperture

9. How lenses focus

Above: The closer you are to your subject the shallower the depth of field (or area of focus) If you want a shallower depth of field move your camera closer to your subject

Depth of Field is greater behind the point of focus than in front of it.
