This shootout is all about the basics: how well the cameras did in various outdoor and indoor situations, and without any fancy modes, filters, or effects. All photos were shot on automatic mode, from the same position, and focusing on the same object. I have resized and cropped the pictures, but left them otherwise untouched. I placed the S3 shots in the center of each trio to make it easier to compare to the camera shots above and below.
Blacks are blackest on the One X, but the S3 and iPhone 4S are the clear winners in terms of sharpness. The iPhone captured more of the yellow flower's crinkly detail -- just look at the top middle portion of the bloom, and the shadowed bottom left.
While I prefer the more saturated blue on the One X, the phone also blued-out the green sea layer between sky and land. The S3 shot has the least contrast of the three in both the leaf shadows and the characters' silhouettes.
My eyes like the S3's deeper greens in the two umbrellas. The iPhone produced the brightest shot, but also the most detail under the main umbrella. The One X has the sharper front-right corner.
Who likes strawberries? This girl
The Galaxy S III is the brightest of the three by far, and with the juiciest red color. However, it also has the least realistic shadow.
Samsung clearly prizes deep-fried Oreos above Apple and HTC. Its camera took the cleanest shot of the heart-healthy boardwalk food stall.
The One X wins this round with both antennas tied behind its back. While the least bright of the bunch, more detail is apparent in more of the tomatoes than both the iPhone 4S and the S3. In general, they're all very good shots.
This one is more of a toss-up. The Galaxy S III is once again the brightest, but the phone also blew out the text on the back of the cable car(all the way to the left.)
Variety is the spice of life
I took this indoor shot without flash. I award Samsung first place for its warm colors and most legible text.
Here's another indoor photo taken without flash to intentionally stress the camera. Overall, the One X shot looks the sharpest.
The iPhone 4S took the best low-light picture of this indoor statue. The yellows are more golden and the details pop. The Galaxy S III came in second, followed by the much flatter, blurrier One X.
