Flash Photography with Canon EOS Cameras

- Great useful guide on flash photography.

“. . . So, here’s some information that may help you understand some of the mysteries of flash photography with Canon EOS camera equipment. Much of the information presented herein is fairly general in nature and thus covers similar flash systems used by other manufacturers, but much is very specific to Canon EOS products.

Note that this document covers Canon EOS products, including digital EOS cameras. Canon’s PowerShot series of digital cameras can use Speedlite EX-series flash units, but since they aren’t EOS cameras there are significant differences in the way they work.”
