Input: Consider Input: one thing to watch out for,when using the zoom button,dont just let it go after you zoom,or it will click and the noise will be recorded. however,if you edit and can dub different audio then it wont matter. that said, we love the camera.ive been thinking about an off board mic for sterio audio,,just for fun. but since this camera is kinda old now,finding extra parts is kinda tough. when we bought it,they were just comming out and then everything was available,but now,several years later,,, well they arent. ebay or maybe canon outlet in the usa.in fact i just bid on a remote for it,we lost the other one. man,they come in handy.id probly also want a clear over lense to protect the main lense from grit and crud. cheaper to get a new cover than new lense.

Output: Positive

Input: Consider Input: Naader was my first yoga teacher. When we moved out of state, this video was my link to the best yoga routine I have ever done. I tried other instructors and other videos, but Naader's approach is the best -- a balanced mix of yoga instruction and inspiration. I have shared this tape with many friends (who then bought their own copy!) and they all agree that Naader's instructions are easy to follow and the pace is slow enough that beginners can figure out what is going on before the next pose; but not so slow that experienced students get bored. Furthermore, since he is doing the poses along with the student, he knows just when to offer that extra word of encouragement when you are about to give up! I find something new to ponder each time I listen to this tape. Naader's words are from the heart and they reach out to touch your heart as well as your body. Buy this tape and use it!!

Output: Positive

Input: Consider Input: This book was a very poorly written effort in my opinion. Additionally, the author would have you believe that the terriorism that exists today is the fault of the U.S and the protestants that make the U.S. their home. It would seem that the author alines himself with Osama Bin Laden and those who wish to control the middle east. It's hard for me to imagine that this man is a professor at Columbia University. Instead of wasting his time here, he needs to return to his own country for the purpose of educating his own people.
Output: Negative
