While I agree completely with Pete about underwater photography re manual use and the indequacy of the algorithm s in cameras for underwater use. The TGs do work well on land and the most useful way of fooling/adjusting it's exposure and focus is the exposure/focus lock produced by a half shutter press followed by recomposition. The exposure setting should be on narrow/spot setting.
As has been said many times the variation in the physical variables due to different light transmission in water means that relatively simple fixed automatically applied rules do not work well.

Evolution is great at solving problems. It's the methods that concern me.
which has really helped - I know the TG-5 & 6 are completely different beasties to the TG-4, and this helps explain *why* they are different. I'd still like to find some footage of the TG-6 at ~20-30m depth with ambient light. Another option is to stick with Olympus & give my son (my diving buddy) a gopro7 & we can compare our footage again :-)
