Has the simplest macbook air 11" the power to run live view software for tethered shooting in the field?
If so, I can see the possibility of accurate focus and full control of composition with movements/tilts outdoors.
With a specialmade flexibel but strong arm on a tripod leg where you can easily snap on the mac air, maybe it is not too bulky....thinking Rm3Di and even skipping the viewfinder and using the 11" screen instead. Batterylife will outperform any DB so that is not a problem.
Anyone tried this?
