"In part 1 of this series, Steve Litchfield looked at exposed camera glass on some phone models and investigated whether scratches really make a difference. In part 2, he investigated the pros and cons of LED/dual-LED/Xenon flashes in camera phones - does Xenon or dual LED flash make that much difference? In part 3, he investigated the fabled 'Megapixel myth' with an objective eye. In part 4, he focussed on the difference between good and poor optics (at the same camera resolution) and in part 5, he pitched all the top smartphone cameras head to head, in detail. In part 6, AAS guest writer Dirk Snoyt took up the theme of camera phone flash research and got all technical on the theme of colours... In part 7, I returned with a look at the difference optical zoom makes and ask the question "Is it better to have optical zoom or just much higher resolution?" Part 8 looked at phone camera video capture potential and part 9 looked at video focussing differences in Nokia's Nseries. Part 10 looked at the difference sensor and aperture size can make, for both stills and video.
In this, part 11, Steve looks at a specific positive from the presence of large numbers of megapixels and discovers yet another use for your smartphone."
