Hi guys, Thanks for giving me such a quick response and useful comments.
Marco:
The exifs are as follows: shot1: 18-70 mm (kit lens) at 33 mm. 6 sec at f22, tripod, CPL. Timer shutter release, ISO 200
Shot2: as shot 1, but 38 mm, f 25
I see what you mean by lack of DOF. I think I need a more expensive tripod. I used Manfrotto 141R, 190 PRO and it had to be positioned on soft ground too.
Andrew:
Thanks. I probably cropped it too much, I thought the stuff around it looked distracting. I agree, the highlights are blown in some places.
Yes, 2300 shots, but it's all behind me now. That's why I disappeared for a while. Mind you, rejection rate was huge, but chosing the keepers also takes damn long time. My work flow is pretty poor, as I am not that good at PPing, but getting better with the right books and advice from here. The other problem is an outdated computer... very outdated
Alpha:
Thanks, See reply to Marco.
John: Good imagination. I see what you mean by a croc's head

Thanks
Steve: Thanks, mate. These were probably the better ones

. The weather was not very good most of the trip, but I did my best.
Matt: Thanks for the comments. Re 1st shot: I knew I should have pushed my wife into the water!!
Kerry and Greg: Thank you. Greg, this was my first try at waterfalls. It's very easy, I think CPL helped bring out colours a bit. I have one or two similar shots, but these were the better ones in my opinion.
I'll feed more of my trip shots in a very near future.
Cheers
Alex
