Proof. Set "No scaling" to "Scale to 8MP" for an easier comparison. This way the iPhone 4 photo is interpolated from 5MP to 8MP, but it still beats the native 8MP Desire HD (= Evo 4G) camera hands down. The amount of detail preserved in iPhone 4 photos is just really really good for a cell phone camera. I admit, the iPhone 4 is a bit noisy, but I prefer noise over noise reduction. The Galaxy S seems to perform almost the same as the iPhone 4, I suspect the iPhone 4 and Galaxy S to have the same sensor.
