Here's something that cannot be done with the iPhone app called ProHDR that was mentioned here a few posts back. HDR = High Dynamic Range, a photography technique that uses multiple exposures at different settings to create an image not possible with a single shot. ProHDR is my favorite app for scenery and other static images requiring RG-HDR (Really Good HDR).
Since ProHDR takes photos a few seconds apart (even in automatic mode) it cannot resolve moving objects for beans. You get misaligned images. The HDR option in iP4's 4.1 software takes the multiple shots very fast. Not only does this reduce the required aligning of hand-held shots, but slowly moving objects can sometimes be aligned.
The adorable little girl in these shots was riding toward me when I took these. The first one is the standard "normal" shot that the iPhone can save as a user-settable option. The second one, though, is the shot that is recorded when the HDR setting on the iPhone camera is turned on. Notice the improvement in both the highlight and shadow detail? Notice that the moving cyclist is sharp enough to make it an adequate photo.
Nice job, Apple.
Again.
Neither of these photos is adjusted in any way since they were taken.
