This has been something on my "to do" list for a while, and I had a dabble today. I've moved onto a lower cost hobby in a sense, fish keeping. This is my latest upgrade marine tank for keeping harder corals. Hard in a physical sense, although there may be a link to difficulty too.

Kit: I used the 7D2 with Zeiss 50mm f/2 makro for most of the shots. Wide view using EF-S 10-18mm.
Software: Microsoft Movie Maker 2012. No expense spent!

While editing I was messing around with a title screen. That was when I realised I didn't do a full tank shot to put the parts in context. So I dug out the EF-S 10-18mm. Noob mistake #1: I looked through the viewfinder, and also the back screen to check composition. Looks good. Only when I viewed the final rendered video did I realise I never checked the focus! It was stopped down so combined with the wide angle, it does have a slight blurry effect which could almost be considered artistic if I hadn't kept it running so long.

Also on review of the final video there are various areas for improvement. Like seeing a reflection of the camera in some shots. I did turn off all lights except that from the aquarium, but there was enough spill to light up the camera. I need a blacker lens front, and perhaps some tape over the Canon logo.

I did suspect the exposure was hot when setting up. The tank lights are very blue heavy which confuses the metering, which is weighted much more towards green. Even though I reduced exposure in parts, the highlights were blown in places. With more time and effort, I think it would be best if I use an optical filter to do the WB correction. A weak yellow should take the edge off the blue-ness.

Great looking tank, I thought it would be difficult growing coral in a tank.

Cheers

Depends on the coral, and what you mean by difficult! Like most things, you need to understand what's going on and control it. Like video production but easier!

Well, I never thought I'd be watching fish tank videos! :lol:

I found the captions worked best when they weren't so central in the frame. Lots to enjoy, though. :)

As said, lots of tweaking to be done.

I recently read about capturing the fluorescence of corals so have done some practice shots of that with stills, and that may be an area for video once assorted filters arrive. Tonight I even took that one step further and tried to look at fluorescence in the NIR region, with limited success. The sensitivity there is too low for video I think.
