Since the release of the first iPhone in 2007, there's one feature that has been steadily improving -- the built-in camera. Lisa Bettany of Camera+ fame provides a visual comparison of the quality of the iPhone camera over the generations in six sets of images covering the range from the original iPhone to the iPhone 5.
As Bettany points out, "It's clear from the detail shots that the iPhone 5 produces sharper photos with more accurate white balance, contrast and saturation." She took photos in three different situations -- a well-lit macro setting to test detail and quality, a skyline shot to test sharpness and saturation and a candlelit low-light macro photo to test noise.
The results are amazing. I was surprised by how much of a jump in quality the camera received in the iPhone 3GS from the previous two generations, and how the iPhone 5 camera seems to have resolved some discrepancies in white balance that existed with the iPhone 4 and 4S. I can't wait to see what the next-generation iPhone will provide for iPhoneographers.
