I wasn't at the meeting but I have a few quick photography tips for you guys. For those with DSLRs, it's best to put the ISO around 400 or less, f-stop around f/11, and if you put a piece of white PVC in your tank it really helps when setting the custom white balance. Most cameras nowadays have the custom white balance option and that is the quickest and easiest way to get all of the blue out of your pictures. Whenever you use it just make sure to point the camera at something that is as close to white as possible, hence the PVC. Also tripods and turning off all your pumps to make everything sit still works wonders. And lastly, when you put your camera on the tripod, use the timer in your camera, usually 2 or 10 seconds. This helps get rid of camera shake caused by you pushing the shutter button.
