Gianchetta, Jim and Roman,

Thanks for the suggestions.

Gianchetta - interesting thought about the wide angle - I can see that would have allowed me to change the perspective quite a bit, and moving nearer the tree could have brought in more of the falls from the side.

Jim - I see what you mean about the middle ground - I will play with that to see what I can bring out.

Roman - this is a stitch of two portrait orientation raw shots. That is why it is square - but I never considered that might be contributing to what I think is a less dramatic photo than I was expecting. I remember now you really need to be careful with square shots.. and use that crop appropriately.

I would welcome your offer to play with my raw files - that would be appreciated and I always learn from that.

I will send them to you when I get a minute - later this week. Really appreciate the offer!

Thanks again everyone for your help.
Dave
