No, I'm not a working pro from the City of Angels, just a local guy who shoots pics as a hobby.
I bought my T3i about three years ago and over the last three years, have been teaching myself how to use the camera to its fullest potential. I'm good at guessing how to set up the "triangle" for maximum light/minimal noise, and have known about Magic Lantern for a little over a year now. I finally installed it now that I feel comfortable enough with the camera to learn how to use the features that ML brings to the 600D.
I have to admit, I kind of was hoping that installing ML would break my camera, so I could buy another one, like the 70D I plan to upgrade to at one point, but nope, installation was a breeze and it all went smoothly!
