help! why did i get MPO instead of JPG?!

[rbelyell]

i just came back from shooting jpegs with my gxr m mount in 'Continuous Low' mode. ive done this before with no issue. this time when i tried to upload to LR4 i got no pictures. when i went into the card file on my computer i saw that instead of the typical 'jpg' suffix i got something called 'MPO'!

i physically changed all 50 individually by hand to 'jpg' and the they showed up in LR4 and uploaded properly.

what the heck did i do wrong?
thanks for your help!

I don't know what you did wrong, but apparently you made 3D pictures: Wikipedia on .mpo.

I think it is the default behavior of the M Continuous mode? I always use the simple continuous mode instead of M Continuous.

oh, ok, thank you alex. i will check the manual. i,m not sure there is an 'M' continuos, but there is a 'Continuous', as well as a 'Continuous Hi' & 'Low'. i used Low, but i think i get your drift.
much appreciated
