iPhone Shutter Release Disguised As A Film Canister
Though I don't have an iPhone, I do like a lot of the camera add-ons. Maybe this is where I turn into an old man, but I can't get over what a good job it does at taking pictures (it's also a nice map, portable game machine... now if only they could get the whole "phone" aspect of it licked...). Apps like Instagram have made it easy to get a retro look reminiscent of Holga toy cameras without any fuss (still not sure how I feel about that), so it feels to me like more people are interested in retro photography than ever.
One of the first accessories you pick up for a traditional film camera is a shutter release, the long snakey cable that pushes the button on the camera to avoid vibration (or put yourself in the picture). Here's a decidedly retro take on it from Photojojo.com. The retractable cable connect to what looks like an old film canister. Unspool the springwound cable and plug it into the headphone jack of your iPhone. Then depress the button on the side of the film canister, and smile.
This is a new product - so new that this is the first day you can get one, and we've got the scoop! You'll also be helping Retro Thing if you use this link to order yours.
