The app requires a cable that works with your camera (not all models use the same type of connector), available as a separate $30 purchase.Īs a simple cable release, TriggerTrap Mobile is definitely overkill, but in the best way. The app offers numerous ways to control your camera’s shutter, provided your camera is one of the hundreds that are supported. Instead of toting several devices for different shutter speeds, you can turn to your iPhone, iPad, or iPod touch and the free app TriggerTrap Mobile. An intervalometer, for example, fires the camera’s shutter at a steady rate over a period of time. Of course, we’re talking about photography, so there are plenty of devices and gadgets that give you this and many other options. To get that shot, you need to switch to Bulb mode and use a manual-release cable to open and close the shutter with the help of a newfangled technology called “your thumb.”
Getting luscious photos of star trails, for example, requires keeping the shutter open for longer than most camera controls allow.
A camera captures a photograph in a fraction of a second, but many creative opportunities open up when you manually control the shutter speed.
