Yes, Grant W has a lot of visual goodness going on in his tank. Multiple shooting sessions were necessary and for each I usually went through two batteries for the camera and had to keep my laptop plugged in.
His tank is decently deep front to back, so I found myself bumping up against how visually close I could get to the frags in the back of his tank with my 100mm lens. There are a couple corals where the best I could do was a full frame "subject shot" that one would see on a site trying to sell a coral. By comparison, I like to compose the shot so that an interesting piece of the subject fills the frame, versus the whole subject. Yes, I could crop heavily, but eventually one looses resolution. I found myself wanting the 180mm L macro lens. I think it would handle the job perfectly. I may have to rent it and give it a try.
Grant W also has one coral which is my photographic nemesis. It's a beautiful purple Turoki, but try as I may I can't get a shot that does it justice. It may be one of those rare occasions that a coral looks better from 3 feet away than up close. From 3 feet away, the colors are continuous stunning shades of blue and purple, but up close the striations in the flesh and color become visible and the continuous appearance of the color is no longer there.
Thanks chingchai.
Shooting remotely allows me to view the image from the camera on my laptop's larger display and to control all the camera's settings from my laptop (except focus). While my camera (Canon EOS 50D) has a large display on back, it's still small compared to my laptop. Also I can trigger the shutter release from the laptop, so there is no jiggling of the camera and hence image blur from pressing the shutter release button on the camera. Using a tripod on the camera lets me use longer shutterspeeds and hence to use smaller aperatures (larger F numbers) so I can get a greater depth of field (more of the subject in focus). Turning off all pumps helps make sure polyps generally hold still during those longer exposures.
