HDR isn't a gimmick, it dramatically improves the picture quality. You get the effect of a super-long exposure on noise level and dynamic range, but with image stabilization, and a compromise on the moving objects in the scene.
- Mikeb85 11y agoHDR is a gimmick in the sense that it just takes information from the sensor to bring out highlights. This is the sort of thing that can be done in post-processing on any RAW image. Its not a feature of the camera itself.
- mayoff 11y agoAndroid and iOS HDR systems take multiple pictures very rapidly at different exposures and knit them together. You can't manually take the same “input” pictures as rapidly as an HDR system.
- dpark 11y agoDo you have a source for that? I've also been under the impression that HDR in most phones is just a gimmick that operates on a single exposure.

- dpark 11y agoThanks!
- reedlaw 11y agoI can tell from experience because some HDR photos taken on my Nexus 4 without being steady for long enough show artifacts of multiple exposures.
- moultano 11y agoThat's not how it works. Here's the google research blog post about it. http://googleresearch.blogspot.com/2014/10/hdr-low-light-and-high-dynamic-range.html http://googleresearch.blogspot.com/2014/10/hdr-low-light-and...
- Mikeb85 11y agoI know there's 2 ways to do HDR. Either way, there's been apps available for that for awhile. Taking multiple exposures with a camera with an electronic shutter (pretty much all smartphones) is still just a 'trick'. BTW, the Galaxy Note 3's stock camera app does HDR, I'm sure most phones already did a year ago...
- moultano 11y agoI'm not sure what your definition of a "trick" is. The quality of the results varies greatly depending on the algorithm used, which is maybe why you don't have a good impression of it. This one aligns the exposures and detects motion which is not something you can easily do by hand. In practice, I find my nexus 5 with HDR+ often takes superior pictures to my consumer grade DLSR, so much so that it's hard to justify taking the DSLR on trips anymore. For instance, compare these two pictures taken at the same spot with a nexus 5 and Canon EOS Rebel T2i. https://goo.gl/photos/8ZrXoEC283oJ3NmC9 https://goo.gl/photos/8ZrXoEC283oJ3NmC9 The nexus 5 one is just way better. The conventional camera struggles to keep even the foreground and midground properly exposed. The nexus 5 gets everything from the foreground to the sky, exactly as I saw it.
