Title: This book is a keeper Review: This is easily one of the better digital photography books I have bought. It's written well and there are lots of photographic examples. The author's work is very respectable and professional. The only thing that I would have liked more information about is shooting photos for large print at 300 dpi - but the book is a few years old and before 5 MP was common. I am definitely NOT reselling this book! It is staying in my library. I highly recommend it, even if you don't just shoot digital. Does this product review convey a negative or positive sentiment?

Title: So-So product Review: I can't say that I own very many of these things, this was in fact my first venture into USB webcams. I was a bit disappointed in the software that came with it and as many have pointed out, image is decent in well lit areas but not at all acceptable in darker settings. USB is the only cost effective way to go for chat cams were quality isn't critical. Does this product review convey a negative or positive sentiment?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
