Don't know what kind is it. It's just eye catching.

TECH
Too lazy to bring my manual wide aperture lens with me so I've luckily managed to shot this photo through the glass by the 18-55mm kit lens.

What I had to do:
+ zooming it at 18mm to get the maximum aperture f3.5
+ pumping the ISO to 800
+ tilting the SB600 head up and setting to TTL

I don't think the SB600 contribute much to the photo due to the low and nearly back ceiling.
