Can someone push me to the correct docs to read for this? I am getting ready to make some new additions to my tourist app for the Danish town I live in. I thought it would be fun to add a camera feature that would overlay a photo of a Viking helmet. Then you line up your subject under it and snap a photo. I have not worked with the camera object before and then trying to combined the photo taken with an overlay and saving to the photo album. I assume this is possible so I thought about reading some doc's on the subject starting with the camera. But if anyone has a better idea for me to start researching to save some time looking around I would be thankful.
