Hello again friends... I leave in just 3 days for central america for a duration of 2 1/2 months, and oooh, I'm excited. Of course the camera comes along (I'm backpacking...the camera and lenses are about 15% of my pack, but ther'll be no sacrificing of weight there!). I am from the United States, and have not been in Central America jungles before. I have experience with fairly low light situations, but the defracted light under jungle canopies and around ruins are unique I;m told. I will be shooting mostly black and white; I'm taking a polarizing filter, a UV, orange, dark blue, an 81B warming filter (for color film), and a neutral density x 4 filter. My question is, which of these are best for low light foliage and dense forest situations? I won't be able to develop while I'm on the road, so i won't even know if i screwed it all up till i get back! Ah, it'll be nice, on top of a volcano, snapping markets and festivals in Guatemala and river trips in costa rica. Any ideas on spots to head would be welcome! Thanks so much!
