Moonrise shots are very difficult to pull off well because of the extreme dynamics involved. If you hadn't put "moonrise" in the title I would have assumed that it was a sunrise or sunset.
Pop, you are exactly right! The only way (I can think of) to get the moon detail is to have done an HDR-type thing - which I am totally "anti" at the moment. Otherwise it would have become far too noisy for my liking if I tried to recover too much in the dark areas. That said, I am quite happy with what I ended up with.
Chris, it is not film - I used Lightroom4 and then Silver Effex Pro - I think it was "High Structure, High Detail", or something like that and then tweaked it a bit. Sorry, I'm not very methodical when I do this so cannot give you more detail!
Riaan, we were with an armed guide so it was not too bad. The crocs all slid into the water when we got near - not to say that I didn't cast a beady eye when I went close to the water! We did the walk a day later, plenty crocs and hippos basking in the early morning sunlight. I was amazed to learn that Ndumo has the second highest concentration of cros after Kruger! Sometimes you don't even notice the very small ones.
Rob - As usual, you are going to have to give me a bit more time to try and work out what you are saying so that my response is appropriate!:)
