Want to learn more about your Canon DSLR without leaving the comfort of its LCD screen? Canon has a series of “on-camera tutorials” that you can load and watch on most of its latest DSLR models. The video tutorials, which cover everything from AF modes to multiple exposure shooting, are meant to be loaded onto memory cards and viewed on-the-go using your camera itself. To find your camera’s tutorials, find and click its model on this products page, and then select “On-Camera Tutorials” at the top. Be warned though: the downloads weigh in at over 150MB each.

Optical sensors are a cheap way to trigger slave flashes if you don’t want to pay for a wireless transmitter, but the fact that you’re firing your on-board flash to trigger the sensors limits your creative options. Flickr user Victor came up with the idea of turning an on-camera flash unit into an infrared transmitter by covering up the flash with a filter. The filter is simply a piece of processed (but unexposed) E6 slide film — it blocks visible light, making it completely black, but allows infrared light to pass through and trigger optical sensors.
