Thanks for posting these photos and some valuable advice in your previous post.
I only hope to take photos half as good as yours.
In the past I have used the disposable film underwater cameras. You never knew how the shots came out until you got home and processed them. The digital camera gives instant feedback and therefore a great opportunity to experiment and learn.
Hopefully, I'll have sunny days and clear water to shoot in.
I'm hoping that someone with TS20 experience underwater can give me some tips on camera setting.
