Before getting into the details, as you can see from the images below. Color was the main differentiating factor. Detail was very similar for all three, again despite the differences in mega-pixels.
The HTC EVO 4G has exagerated colors, on the artwork but the grass in the background is slightly muted. Other images with strong red colors blew out badly too, resulting in lack of focus.
Noise was again a problem for the EVO.
The Kodak seemed to have the most accurate color but lost some detail, especially on the cheek. The Kodaks noise levels seemed to be the lowest of the three as well.
The Olympus did well on detail and noise. Again the 2.1 mega-pixel limit didnt seem to hinder the camera. The color was way off though.
The winner, by just a hair was the Kodak Easy Share C533 in this test. Most cameras are going to do reasonably well in these conditions and I really would have been fairly happy with any of these images. The HTC EVO 4G was probably at the bottom of the pile...again.
