Your photos are good to great but at your first night at Halali waterhole I realized that you from the USA! Loud! Please respect other people! Whisper around the waterhole as others want to hear the calls of the bush and not about ISO and F-stops! You first mentioned spotlights to be used and at the end you mentioned strobe, its the spot light that is the problem and more a problem for wildlife in the night as you are blinding them! Sorry that I'm a bit harsh.
I have to presume you were actually there otherwise your comments are totally unwarranted as you can't possibly know what was objected to?
