it talks more about aperture, shutter speed and setting a correct exposure.
subjects to learn more about composition:
the rule of thirds and the golden triangle
^ you can look for sources on the net which explain those very well.
i got a book by the same author called learning to see creatively and it had a whole section on composition. its a good read, i was actually looking for understanding exposure and saw that and picked it up.
I like books. I found a collection of Kodak how-to books at the local library for sale at the used book store part. Looks decent, I was lucky enough to pay my dues as an art student years and years ago.
