I can't recall if I shared these or not yet but I recently had them done on the side of a building as murals.
Just wanted to share because they look really awesome in real life and I'm happy at how well they turned out 
....and really, 21 megapixels is probably all one needs for just about ...printing anywhere near this size. I doubt anyone prints this big on a regular basis. 
They printed no problem. I believe the total size of Synapse is 90x216" Pelican Light Painting is half of that or so.
If I recall correctly Synapse was about the equivalent to a 150 megapixel image and Pelican Light Painting was a single shot on the 5D mark II (21 mpx)
Yes I know Pelican Light Painting is flipped, a lot of people thought it looked better that way. I prefer the original but am open to whatever looks best, it's mounted the side of the building permanently now

I'm really happy for the way it turned out and just wanted to share...if you have some epic imagery sitting on your hard drives that you think would look real good done up big...then don't be shy! Print it big and put it somewhere where everyone can see it! Or just yourself to enjoy, whatever.
