Thanks for that: I was quite proud of the luck...and I call it luck. As you know, getting a really good picture under water means getting much closer to your subject than when you're on land. My usual tactic was to use a zoom lens and that was a disaster because most of the pictures taken that way weren't in good focus, for all the reasons you already know. Yes, I do have a few more good ones which I'll be posting on this website. It's a shame that I'm limited to only one picture every 24 hours without 'donating', so be patient.
