megapixel camera vs analog camera image
Qwerty
Ok, so I'm thinking about upgrading to a digital SLR camera from my 10megapixel bridge camera, and I was looking at getting the Nikon D40, but it's only 6.1 megapixel. Will this make a big difference in terms of image quality, or will the larger CCD make up for it somehow? Please explain how it works.
Thanks in advance
Answer
Mega pixels is basically a myth. More is not necessarily better. What matters far more is the size of the pixels. The sensors on most DSLR's are nearly 15 times larger than the sensors on point and shoot cameras. Therefore the pixels are 15 times larger. Larger pixels deliver better detail and less noise than smaller ones. Point and shoot camera with tiny sensors packed with lots of pixels actually generate more heat and noise than they would if they had fewer pixels.
Enough about pixels and sensors. The image quality of even the cheapest DSLR will be far greater than even the best point and shoot. The reasons are that DSLR's have much better optics, much larger sensors, better faster processors and much better analog to digital converters.

70mm Imax vs 1080p blu ray?
Taylor
Hi I was wondering which has the best video quality a movie shot using a Imax camera and played in a 70mm Imax theater or a good quality blu ray disk played on a home HDtv or projector. Also are 70mm Imax projectors always professionaly calibrated because I know that is a problem with some theaters.
Answer
70mm IMAX is shot on 50mm analog film, and played back in analog format. It is hard to directly compare it to digital, but it is equivalent to roughly 27 megapixels. Blu Ray is a little over 2 megapixels. IMAX is designed to look great on a humongous screen. If you showed Blu Ray on the same humongous screen, you'd probably notice the pixelization, but will look great on a smaller, home screen.
