Canon produces a wide range of cameras, lens and accessories for photography, including external flashes. These external flashes are powerful, solidly constructed and produce good light. They are also compatible with Canon's Evaluative - Through The Lens exposure systems, E-TTL I and II. If you use the flash with a Canon camera that also uses these exposure systems, the flash will adjust itself automatically to the correct power setting based on the exposure of the scene and its composition. The flashes are easy to use with any camera, however.
Instructions
1. Insert four AA batteries into the Canon flash. Slide open the battery door on the side of the flash, insert the four batteries in the orientation described on the interior of the battery door, and close the battery door by sliding it shut.
2. Attach the camera to your flash using the hot-shoe adapter foot, located on the bottom of the flash unit. This plastic foot slides into the metal or plastic clip on the top of your camera from the rear. Once the flash is in place, tighten the connection by turning the knob directly above the hot-shoe adapter.
3. Press and hold the "Power" button until the flash turns on.
4. Listen for the tell-tale whining noise to indicate that the flash is charging.
5. Press the "Mode" button to switch between modes on your Canon flash, including manual, automatic and E-TTL.
6. Adjust the flashes power by pressing the "Mode" button until the fraction on the top-middle of the LCD screen flashes. This is the power setting for your flash and can be adjusted in manual mode. Use the up and down arrow buttons to adjust the power up or down. When you are finished, exit the flash menu by pressing "Mode" until nothing on the LCD screen is flashing.
7. Press the shutter button to activate the shutter and take an image. The flash will fire when the shutter does, adding light to the scene.
8. Examine the image on the back of your DSLR camera to check the amount of light added to the scene and adjust the flash's settings based on the result.
