Although the camera on a 4S is not that good compared to the new and shinny iPhone 5, the new panorama in the camera app is really stunning!
Follow the arrow and voila, the photo just appear like a magic. No more stitching in Photoshop.
Here is the panorama from yesterday hike. I did a little color adjustment and cropping to cut out uneven corner, 90% is straight out from the iPhone. Kudos! Apple!
Have a nice day!!
