Subject:Re: What's a Gigapixel?

Thread:


No it simply is not, a 6mp camera like the D70 has images which are 3000px x 2000px or 6 million pixels hence 6 megapixels. You can look at it anyway you want but a gigapixel image has to be 1,000,000,000 pixels regardless of the projection, crop etc. If the final image doesn't have a billion pixels then it aint a gigapixel image.

I do love how panoramic photographers seem to be addicted to making things more convoluted and more difficult then necessary.
