What happens when you squish together the best of underexposed and overexposed photography? You get HDR —high dynamic range images. Here are 37 examples of what HDR can do.

HDR is the process of combining multiple photos with the hope that the resulting image is clear in both the light and dark areas. Getting good free HDR software that is capable of merging the photos together can be a little tricky since there are a lot of things it has to take into account, such as perfectly aligning each image.

Picturenaut is a free HDR app for Windows that has done a wonderful job with my photos. The program has been in the works for over 4 years, and you can tell that a lot of sweat has been put into making it. Merging your images will generally take just a few seconds, and with the settings available you are able to tweak the resulting photo to look exactly how you want it to.

Here are some of the high-level features offered by Picturenaut:

• Automatic image alignment
• Exposure correction
• Color balancing
• Ghost removal
• RAW support
• Noise level compensation
• Full control over camera curve

Sure, you love the HDR pictures coming from your point-and-shoot, smartphone or perhaps even your Glass. But what if you want to Hangout in HDR? An enterprising grad student from the University of Toronto named Tao Ai — under the tutelage of Steve Mann — has figured out how to shoot HDR video in real-time. The trick was accomplished using a Canon 60D DSLR running Magic Lantern firmware and an off-the-shelf video processing board with a field programmable gate array (FPGA), plus some custom software to process the video coming from the camera. It works by taking in a raw feed of alternatively under and over exposed video and storing it in a buffer, then processing the video on its way to a screen. What results is the virtually latency-free 480p resolution HDR video at 60 frames per second seen in our video after the break.

When we asked whether higher resolution and faster frame rate output is possible, we were told that the current limitations are the speed of the imaging chip on the board and the bandwidth of the memory buffer. The setup we saw utilized a relatively cheap $200 Digilent board with a Xilinx chip, but a 1080p version is in the works using a more expensive board and DDR3 memory. Of course, the current system is for research purposes only, but the technology can be applied in consumer devices — as long as they have an FPGA and offer open source firmware. So, should the OEM’s get with the program, we can have HDR moving pictures to go with our stationary ones.

We’ve wondered what HTC would do after a Dutch court banned it from using HDR Microphones in its oft-delayed One handset, and now we know. It looks like the company has now nixed references to the Nokia-developed component on its website, raising the possibility that the handsets currently being manufactured have HTC’s “improved” microphones rather than the original STMicroelectronics unit on board. None of this should affect phones that are already on the market, but we’ve reached out to HTC to find out what this means for future One owners and will let you know more when we do.

[Thanks, Ted]

Update: HTC has reiterated its position (after the break) saying that the company is entitled to use its remaining supplies of STM’s HDR Microphones until they run out.

CyanogenMod 10.1-toting photography fans are in for a treat: the latest version of the modified Android OS now packs an HDR mode, which was in development for three months, within its stock camera app. When a user snaps a photo with the function, a total of three pictures (one at minimal, neutral and maximum exposures) are taken and combined into a single HDR image with the help of an algorithm. Differences in shutter speed, sensors and optics means quality will vary across smartphones, but the CyanogenMod team says that mid- to high-end devices outfitted with decent imaging hardware — especially those with zero shutter lag — should perform admirably. Of course, the group also recommends using a stand or tripod to thwart movement and vibration from fouling up photos. Android Central points out that a few handset builds haven’t received the update, so a handful of CyanogenMod-wielding photogs will still have to get their HDR fix elsewhere.
