My best mistake

What photos did you get by mistake that ended up being amazing ?

I was really trying to get a good photo of the front of this shark but the best one I got was of his rear end 

Wow! Love this. Very cool, Chris

I think this was my best mistake. I had just switched from shooting with half-press-to-focus to using back button focus. On this shot, I completely forgot to press the AF button on the back, so the focus was purely luck!

Wooohooooooo! Another terrific mistake! Nice one,  Stuart!

Thanks, Tim! It was VERY lucky, for sure!

Yeah, but as Arnold Palmer said, "the more I practice the luckier I get"....

It's a wicked shot!

Good quote indeed

Perhaps this shot of a Star Horseshoe Worm pulling back into it's hole?

Or maybe this Peppermint Shrimp - the only one I've ever seen?  I had photographed an Azure Vase sponge as I went past it.  A bit later I swam over it on the way back and just took a shot straight down into it.   Thanks to having 36mp of detail available, I was able to crop in to get an image out of the shot.   It was only in post-processing that I noticed the shrimp.
