Trey Ratcliff is the well-known and well-loved HDR photographer behind the travel photography blog Stuck in Customs, and in this behind-the-scenes video he talks you though his gear and how he sets up a few shots of this rocky beach in the Virgin Islands. The video offers some great insight into Trey’s thought process as he composes the resulting HDR images, one of which you can see in higher resolution (including some 100% crops) here.

Reddit user MacTuitui created this simple diagram (click to enlarge) explaining the idea behind HDR photography. The first low dynamic range (LDR) taken normally with a camera isn’t able to capture much of the detail found in the highlight and shadow areas of the scene. Two (or more) photographs are then taken at different exposure values to capture a wider range (the bracketing step) and subsequently combined into a single image with a high dynamic range (HDR). Since most displays aren’t capable of displaying this full range, the image needs to be tone mapped to have its appearance approximated on LDR screens.
Apple had a special event this morning where they announced a few new products. In addition to the introduction of HD-video recording on the iPod Touch, an interesting new announcement was the HDR Photography feature in iOS 4.1, which is found on the iPod Touch, iPhone, and iPad (though the iPad doesn’t currently have a camera).
On the Apple website, the description of this feature reads:
Take great photos that capture a wider range of light intensity using the new high dynamic range (HDR) setting on iPhone 4, which automatically combines multiple exposures into a single HDR image.
Hopefully the feature is flexible and allows the user to tweak the resulting photograph.
Automatic HDR modes are becoming increasingly common on consumer cameras, and may become a ubiquitous feature before long. You’ll be able to download the iOS 4.1 update soon.
