More iPhone4 HDR

Here's a snap, with HDR (High Dynamic Range, meaning photography in high contrast conditions), and the auto-saved sample without. It's plain that it does save a great amount of data in the highlights.
It also tends to make the mid-tones kinda flat. But it is tricky processing, and maybe future updates will improve on that. In the meantime it can be helped in the computer.



HDR, adjusted with Curves in Photoshop:

"Curves" in Photoshop is simple on surface of it, you just pull at a tone curve. But it's trickier than one might think, because small curve changes make big differences, and it easily gets to look very odd.
