There’s an interesting article over at DigitalCameraInfo on whether the Megapixel War is over or not. You weren’t even aware there was a war going on? It’s the one where camera manufacturers tried to sell you new cameras with ever more pixels because you thought (and sensor engineers will publish technical papers to prove it) that more megapixels meant better images. Up to a point, this is true and certainly true on large sensors which have still ots of space to accomodate even more pixels. But on the tiny sensors (you’d be shocked if you saw how tiny the image sensor in your digital camera or phone is), more pixels usually mean worse quality images.
