Constant Light or Strobe?

It’s always fun to experiment with different techniques underwater.  As I am in Lembeh with the Underwater Tribe and no particular deadline or assignment in mind I have been using the time to try out a few different cameras and shooting styles.  One of the styles I have been playing around with is the use of “constant light” from a powerful underwater light, my Fisheye FIX 7000 in this case.  The results have been fairly encouraging, even though I have only tried it a few times with no real scientific basis behind it. The photo above is from the Panasonic GH-4 in a Nauticam housing with 12-50 lens with the settings of 320 ISO, f8, and 1/100 and the Fisheye FIX set to 50% power.  I am sure that if I spent a bit more time on lighting I could have achieved better colour but it was a quick and easy snapshot in shallow water (about 5 metres) just to see what I would get.

On the other hand, here is the same frogfish shot with a single Sea and Sea YS 110 alpha strobe with the same camera set to: ISO 320, f22, 1/200.  The colour saturation is obviously better on this shot and if would certainly work better as a print or published photo, however, there is nothing wrong with the constant light image and it looks fine on social media and the web.  For folks not interested in the finer points of having to deal with fstops and strobes then this is a nice combination that gets good results.

These shots are straight from the camera, I am sure with a little TLC in Photoshop or similar then the constant light photo could pop the colours as well.
