Eric, Yes I am still here... I remarked some time ago that when I use my D3100 I tend to use it as a snapshot camera, I just grab it and press the button. I have it set on full auto, shock horror!! When I am greasy up to my armpits and just need a quick pic of some tremendously interesting bolt or floggle-toggle, I can't be a**ed to make manual adjustments, I just want a usable pic.

Anyway I have remarked that often the auto can produce remarkably good images, better than I might expect had I made my own manual settings at times. I sometimes wonder why the auto can produce such good images.

I seem to remember your reaction was to take the same image in both auto and using manual with my idea of what settings I thought appropriate for the scene, then compare the EXIF to perhaps reveal it's secret techniques.

I have noticed that depending on the scene, in full auto, various focus points flash in and out as I compose and zoom the lens to optimise the image composition, they seem to lock on to points and features of the subject but any of the focus points can activate depending on the subject. I am wondering if you did the reverse of what I am doing and took some fully auto exposures, as well as some manual, or semi manual exposures, then compared the EXIF's and of course the images... Then perhaps that might clarify what these multi point focus points are actually doing.

I realise my D3100 is somewhat primitive compared with some of the more modern bodies but it's the principle I am thinking of. Just a thought...
