Coral, Vinpearl Land, Nha Trang

Don't know what kind is it. It's just eye catching.
For Vinpearl Land, see the details in this link:

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.
