Making sure that you jump into a self-snapped family portrait at just the right time before the shutter of your camera fires can be difficult unless you are using a remote timer such as the Satechi WTR-A.
Designed for operation with the Canon line of DSLR cameras, this wireless remote control can control your camera's shutter clicks and be programmed to automatically perform a series of timed photography tasks that would normally be tricky to achieve otherwise.
The device is particularly useful when you want to act as both the photographer and the subject and need an automatic timer to snap the photo at just the right moment. It is also a helpful tool for long exposure photography or when taking time lapse shots.
The timer also eliminates the slight camera shake that can occur from snapping down the shutter that could cause an otherwise perfect time lapse sequence to become blurry.
