I am waiting to get my d40 delivered to me and i am going on vacation in a few weeks, my camera will be going too. I was wandering if anyone had any tips for taking pictures of the waterway there or through glass (going to the serpentarium there). All i have is the camera with the kit lens and no money to buy anything else. Any advice would be appreciated. P.S. Just a random question, but would a circular polarizer filter give the appearance of no reflections in a mirror?
