The iPhone's iSight takes great photos under a wide range of conditions, but you still need to have it in your hands, ready to shoot, whenever the need arises. Sometimes that's when you least expect it. Sometimes that's when you see something spectacular or your child does something amazing. It's not planned, it's not posed, but it's still incredibly important to you. That's where quick camera access comes in. Apple knows you may need to get to the Camera app in a flash, and they've built in a great way to get right to it!
