Do you mean fix the pictures that you have already taken? or stop future pictures from being blurry?

Get an old Hasselblad or Polaroid - then you have no choice, its Square :-)

comment What is special about the SENSOR in a Light-field camera?
I thought you'd do a bit more digging on that :-) They also go on to say in the Tech specs that there are 100 pixels per micro-lens (that being a 10x10 array)

comment What is special about the SENSOR in a Light-field camera?
aaaaaah OK! that makes sense. I was struggling to figure out how on earth you could measure the incident angle of light onto a single pixel. However, lets see if anyone can give more than an "As far as I know" answer...

Is it a photograph of the artist's work? as that changes things again...

comment How to calculate the optimal pinhole size?
I'm struggling to figure out how the value of d relates to the pinhole size. I had an answer (based on c=1.414, f=50mm) of 234? if this is mm thats a bit big! if thats nm thats far too small... Should all figures be in nm, mm, etc??

comment What is the difference in purpose between a focal plane shutter and a leaf shutter on a camera?
Ive resisted putting this as an answer - a VERY important feature of a lens-mounted shutter is flash-sync. it is well known that a lens mounted leaf shutter can sync to 1/1000th+
