Is there such a thing?
I have a lot of A4 documents I want to photograph. I have a camera stand to position and hold the camera over said documents, so that I can change the document beneath the camera without the fiddle of re-aligning the camera for each document. But the action of activating the camera shutter often moves the camera. What I need is a short flexible shutter release that plugs into the camera and allows me to take photos in fairly quick succession without having to realign the camera every time.
They exist for 'proper' cameras, but I can't see anything that simply works with an i-phone.
