Photo Credit: Aurora HDR 2018 test image
This is the test image that comes with Aurora 2018. I processed this from a recipe I created as a result of a photo I edited for a friend. Applying that recipe to this test image, it rendered good results, though I still had to apply a mask to smooth out and decrease the contrast of the sky and water a bit (was dark with sensor noise). The sky is somewhat painterly, but in this case I happen to like that effect for this HDR image.
