Google releases data to help improve HDR imaging

The smart folks responsible for HDR+ on the Pixel 2 are sharing a big dataset in order to help other developers create better high-dynamic-range imagery:

Today we’re pleased to announce the public release of an archive of image bursts to the research community. This provides a way for others to compare their methods to the results of Google’s HDR+ software running on the same input images. This dataset consists of 3,640 bursts of full-resolution raw images, made up of 28,461 individual images, along with HDR+ intermediate and final results for comparison.

[O]ur hope is that a shared dataset will enable the community to concentrate on comparing results. This approach is intrinsically more efficient than expecting researchers to configure and run competing techniques themselves, or to implement them from scratch if the code is proprietary.
