first... finishing an old keyboard by moving its keys to the desired positions...
then... 30 seconds exposure time in total darkness, using a lamp 3 seconds focally on each of the 10 keys ! I'm a bit worried that voters will imagine that these keys were back-lighted, and that they'll see that only the top flat surface and not the sides are lighted up... let's see !
Your keyboard is a little different than mine. :-) I like the concept and originality. This photo also meets the challenge appropriately. Overall, good job!
I am a little curious as to how you accomplished this photo. Very unique in its concept. I would have scored it higher if you could have gotten the keys a little more white.
