The gas station example was mentioned again in this meeting.
I wrote about the RED Xmas example, my own simple 3D tests to understand the issues with this image and shot one morning some quick photos with my iPhone.
The weather was good today so I went out and photographed a similar gas station, but this time with 7 exposure brackets on a tripod and with the same workflow as the Pruis photos from the beginning of this year.
Please feel free to download it and use it for any sorts of tests. HiDrive
I did not had an ND filter with me so the sun clips around 500 at the current exposure.
