Ken - Having seen countless stunning pics from your Amazon trip (and believe me I'm not even a little bit envious ) I just have to congratulate you on hitting the focus "sweet-spot" every time. Hand held in low light too! Remarkable!
I must say they are quite colorful and all are excellent shots. I really like the way the eyes were captured in the third image, so sharp and clear. Wonderful images Ken
Yes, the low light conditions and my inexperience with adjusting corresponding exposure appropriately was a huge handicap. Fortunately, very few of my 'nonkeepers' were due to focus issues, I seemed to be on a roll as far as focus goes. I used no tripod, though the vast majority of the shots were taken with a monopod...not as stable as a tripod certainly, but much better than purely hand held. What made it easier was that most of these subjects did not move much at all.
The trip was really not that expensive in comparison. I say if you want to go, then find a way. 10 days in the Amazon, everything paid for (except airfare) for ~$1600...not too shabby. I think a week was ~$1300 and then $100/day after that. A trip to remember, that's for sure. Good food, great lodging, great guides, you make your own itinerary, etc.
