I was going to chime in on this one but forgot, and also noticed everyone had it covered quite well. Morale of the story is it's like anything else, isn't it? I'm definitely no expert, but one just has to shoot depending on the conditions. When we were in Vanuatu in the second resort we stayed at there was this beautiful root system on this tree we'd walk past on the water's edge every single time we walked somewhere.

I don't think I took a photo of it until day 4 (out of 5) when the tide and time of day were just right. Of course, even though that was okay, I couldn't have forecast my kids would come down and make the experience as difficult as possible, lol.

But yeah, the low angle is something I'd recommend as well as the lighting, which I guess is like any photo you want to take.
