I you already have a DSLR in a housing, it is so simple to take some video grabs showing behaviour that still shots would just not do justice.

I agree Andrew.
Also, when we were at Sublime Point the other morning, I felt that a Video would have been good the record the changing light.

Spare body with intervalometer will record the changing light very effectively. I've even managed to capture the odd lightening flash that way.

A D200 would do the trick there...or a D300.

Andrew,

I can think of many uses for high quality video from a DSLR. Sure, and intervelometer may help certain applications but video is different is better for other applications.

The lighting is going to be a problem though. Do you guys carry constant lights down in the depths? [or you can crank up to ISO 1000000000000000000000 in about 5 years time ] and light with low wattage lightweight LED constant lights

I've shot available light down to 18 metres at ISO 200. White balance can be a problem, but being able to capture behaviour overrides the disadvantages of poor white balance, in my opinion.

This shot was taken at a depth of nearly 15 metres, off Sydney:


In shallower water, and in the tropics, light will be less of an issue.

Thanks Andrew,

I didn't realise that there was that much light at 15m! Fancy you getting a fairly sharp picture at 1/60.

I watched the sequence...and a D300s with video would have been great for you there!

Well, the lens was at 12mm, so in theory I could handhold to 1/12s. Having a large housing in water also tends to reduce camera shake.

Camera float?

Camera sink?

OK Iv'e never even considered video on my SLR but am starting to think about it - quick question ...If I choose to take a still from the video what is the quality like c/w the same still taken as a still ?

Deb, it will be normal quality but you get a gap in the video.

So if I take a video , get home and want to isolate and print 1 frame it will be quite usable ?
Deb

Sorry Deb, Didn't understand your question earlier.

In your case, you will get a photo at 1980X1080. The noise characteristics and color will be still better than your consumer type of camcorder.

Deb

you will get a roughly 2mp still image (from a Canon DSLR), so it will be small but printable.
