Wozniak loves Windows Phone 7.5

Windows I wish more people who work or have worked for large technology companies were as open, honest, and excited as Steve Wozniak still gets over new technology and gadgets. He recently bought a Nokia Lumia 900 - and he's loving it. So much so, in fact, that he claims it's better than Android and iOS in many respects.

Megapixels are not an accurate measurements of camera quality. They are just a measurement of image resolution, that is, how large of a print you can make from an image and how much you can tweak it because things start to become really ugly.

Digital pictures have been high-res enough to make decent A4 prints ever since 3 MP cameras have been out. For casual photographers, there is no need for higher-resolution pictures.

Now, stuff that actually matter to phone camera users, such as color fidelity or noise, may actually be harmed by an uncontrolled push for more megapixels. More pixels means smaller photodetectors, so a lower sensitivity and more defects.

Not even that: a technically high MP file from, say, a phone camera and its very small sensor & poor optics (poor "optical resolution" of sorts) ...will tend to give worse large prints than a proper DSLR with, say, nominally only half MP.

Digital pictures have been high-res enough to make decent A4 prints ever since 3 MP cameras have been out. For casual photographers, there is no need for higher-resolution pictures.

Probably more than A4 - I remember one informal experiment with three poster-sized prints of the same photograph, in 15, 10 and 5 MP versions (and A4 to poster increase is proportionally larger than 3 to 5 MP). IIRC, out of dozens of people, only one could pinpoint the difference ...probably due to being a pro in the field.
(I'd have to search for it myself, and I'm afraid ATM of wiki/google effect ;) - if you care, it was IIRC some NYTimes blog post dealing specifically with the megapixel myth, test done in some shopping center or some such)

PS. Kinda like megahertz myth of old days...
