Some have recommended using a graduated ND filter when photographing Machu Picchu. I'm shooting with a 20D & have a circular polarizer. I probably won't take my tripod as it's just too much to manage on this trip in addition to the other equipment.
My question is, is a graduated neutral density filter really necessary or is shooting with a circular polarizer good enough to get good shots? I'm going to experiment with taking hand held HDR shots before I go to see if that's a possibility with a really steady hand.
I'd appreciate any helpful advice, especially anyone that's shot a lot of landscapes or even Machu Picchu.
Thanks.
