As a hobbyist photographer this definitely sounds interesting in terms of allowing more control over the camera (especially automated uses, build your own timelapse, get past the 30s long exposure instead of having to buy a $150 canon timer remote, et cetera). But doing anything with image manipulation and transfer (maybe there's a reason Eye-fi hasn't moved into the DSLR space -- no CF version, only Class 6 speeds) seems like a daunting task for the pi..<p>For those more familiar with the Raspberry Pi, does it actually have enough performance to move big RAW files around? A 5D3 will output ~30MB RAWs and in a shoot you may end up with 500+ of them. Having a Pi transfer/move/adjust them sounds like a slog.
