6mpixel.org started BIOS-Pixel Initiative on Photokina 2008 (BIOS = Better Instead Of Smaller). The initiative is supported by the German test lab Image Engineering, the magazine ColorFoto, the online magazine heiseFoto.de and Ringfoto, a dealer association.
One problem with their approach is that they use unified lighting conditions and test chart to check "good pixels". In fact, "good" or "bad" pixel quality depends on a lot more things, such as illumination, scene, lens quality, AF quality, AE quality and many other factors. So, with all these factors unaccounted, the tests, that the Initiative proposes, have very limited value to me.
