Way underrated! I swear the voters here amaze me sometimes, and not in a good way.
However, I do think a tighter crop on the right would have helped some. The dead space doesn't really add anything, IMHO. Should have been in the high 5's.
So that's what they look like during the pop...great idea! Those reflections at the end of the bulb are amazing...for me, the crop is somewhat disconcerting, I'm not sure why...I think it's the long and squat proportion that's a bit strange for me..anyway, still an awesome image!
