The iPhone 4 may be the only iPhone to have “legitimate” HDR photos provided by Apple currently. But if a leaked image from the latest SDK is any indication, we could be seeing HDR photos trickle down the iPhone family tree just a bit. Having Apple-provided HDR support is a big deal, so much so that Apple received quite a bit of flack when iOS 4.0 features for legacy devices was announced and HDR photos was absent. Then again, if you really wanted HDR photos on your 3GS or 3G, there are several options already in the App Store.
Don’t be too distraught if such a feature doesn’t come, however. Just because there’s a rouge icon floating around in an SDK doesn’t mean we’ll see anything become of it.
Is this something that interests you? Have you already downloaded an app or hacked the feature onto your phone? Do you even care?
