Adobe has updated Lightroom mobile with a new Raw HDR capture mode that takes three DNG exposures and automatically aligns, merges, de-ghosts and tone-maps the image to deliver a 16-bit floating point DNG.
In the clip above, Russell Brown provides a short tutorial on the new feature, showing off the increased dynamic range it provides.
He points out that because three exposures are required it isn't a good approach to moving subjects. And that the size of the files are larger than usual so file transfers will necessarily be much slower than JPEG captures.
Adobe said the initial release of HDR for Lightroom mobile supports any iOS device that can capture in DNG "such as an iPhone 6s, 6s Plus, 7, 7 Plus, iPhone SE, or iPad Pro 9.7."
Android support includes the Samsung S7, S7 Edge, Google Pixel, and Pixel XL.
In explaining the limited initial support, Adobe's Josh Haftel said:
So that we'd adhere to our stringent quality and reliability requirements, our primary goal was to ensure the stability of the app while enabling the algorithms to provide the highest possible quality. Thanks to the processing and memory available on the Samsung S7 and Google Pixel devices, we were able to achieve the quality and capabilities required by these incredibly powerful algorithms. The team is working hard to support additional devices as quickly as possible.
Other major new features in the iOS version include:
- In iOS you can now Export Original, including DNGs and Raw files you've imported.
- Gestures now speed up Rate & Review mode.
- There's a new Force Touch and Notification Center widget.
- A Prevent From Sleep option in Settings will keep the screen from locking up if the phone is plugged into power.
- Improved synchronization stability and speed.
- General bug fixes, performance enhancements and UI tweaks.
On the Android version, the new features include:
- Radial and Linear Selection tools are now available.
- General bug fixes and speed improvements.
