My first impressions of the picture quality when I connected it in to my PC where "incredible and unreal!".
I have used most of the Logitech range of webcams down through the years and the top end webcams were always very good. However this webcam is a world apart. The quality of the image is incredible. It easily compares to digital consumer camcorders for example that are three times the price.
The thing that struck me first was how true the color was represented. I could not distinguish the onscreen color to the color when viewed with the naked eye. Many webcams add their own tone to colors. But the 9000 rings true. What you see is what you get.
One of the key things with stop motion animation is the ability for close focus on detail. It's a feature that is lacking in many webcameras available today.
