It would be really nice if there would be HDR support in the camera application.

I would like this very much too.

This would be really hard to implement well, since there's no camera mount Other halves yet, and the photos should be taken from virtually the same place. Also, the good, natural looking tone-mapping algorithms are really processor intensive.

@pnuu: I don't think so. there are cameras available, that do it quite well without the use of a tripod - sony nex for instance. And may I remind of a very usable camera app for the n900, which had a usable HDR feature: http://blessn900.com/

I think, such feature-craze stuff should really be done by the community or third parties. So, I think, we should ask for the interfaces to do so and not for the feature itself.

@stephan, How do those cameras/apps co-align the images before tone-mapping to LDR? I guess FFT image correlation would be fast enough in some cases.

By now when eg. Turing Phone announce that their phone supports HDR functionality i hope that Camera app get updated to support that.

"CAMERA: Primary 13 MP HDR Dual Flash, Secondary 8 MP HDR"

Photos of the enterprise taken with Turing Phone Sailfish 2.0.4.14 and no HDR support as far as i can tell (this is a initial test hardware unit).

If this was an HDR camera- software then more details about the background lamp shade should be visible .

HDR is a mode that needs to be activated (when then available) as you usually do not just "snap" HDR, do you? Would be very odd to have everything HDR, I for sure would not want that.

a process to have HDR picture would be to make a set of photo of a view with different type of exposition luminosity (all other parameters are fixed), usually 3 different one, which is called bracketing. Most of the time we should use a tripod that give a storage stability for the device avoiding small moves between each pictures. Then there is some tools which merge all of the pictures. Make HDR pictures needs some rigorous conditions. not that simple with such a device like a smartphone. Better are reflex devices, which are automated on typical luminosity and depth (possible in smartphone too, but with which quality?), and store them really fast (and some of them make the rendering too)...
