The iPhone 5 isn't a week old but we're getting a lot of great photo analysis. In particular, Apple touted an upgraded camera, and folks are comparing it to the iPhone 4S and the Samsung Galaxy S3.
As you might expect, the 5 has a better camera than the 4S, although iMore notes that the 4S shot photos that seemed warmer. Check out their side-by-side comparison shots covering a range of shooting conditions here.
The Galaxy, however, is a big question. As a major competitor, Samsung needs to make sure its cameras are at least on par with Apple's. Unfortunately, as Creativebits discovered, they are not.
Of course, the question is whether consumers will notice the difference and buy accordingly.
