Not exactly sure what the ISO is, but learnt that a low (100 is the lowest, 1600 the highest..) one makes the shutter close longer and if you are not still and/or your object isn't (yeah, ask a one year old not to move...) then you will see movement, or even transparency.


Oh, and a darkish room and no flash!

(love this one.. )

I wonder what a steady one would yield.. (but that's an experiment for another time..)
