The M doesn't have a Macro mode on the camera. That came as a surprise for me. Found an app called 'Magnificent Magnifier HD'. I'm like amazed. It works. I have never seen a camera app that did anything more than what the stock camera did but this one fills the niche I needed to take pics of flies I tie for fly fishing. Will post some as I take them. Blown away. Why can't the stock cameras do this?
It says it's for Gingerbread and ICS but it works on the M with JB.
