An article on TUAW today pointed out something I didn’t know: you can use Apple earbuds to snap the shutter on an iOS device when taking pictures. The article mistakenly says that you must snap the Volume + button; both volume buttons work for me.
But what’s interesting is that it’s not just Apple earbuds that will do this. I tried with a pair of Sennheiser PX 100-IIi headphones, which are my standard wired headphones. This, like many other headphones these days, has similar buttons to the Apple earbuds.
This feature is great to know about. I have a tremor, and find it difficult to shoot photos without blur using my iPhone. Now, I’ll keep a pair of earbuds with me for when I plan to take pictures, and don’t have my digital camera.
