Tried to play with Luminar and Aurora HDR 2018.

This photo was processed with Lightroom and Luminar 2018. I decided to see how it will look in B&W so I converted a regular photo taken at night in May, 2016
 

and converted it into B&W. After it I exported TIFF file to Luminar 2018.
Here is a final result

Then I decided to create HDR from 3 B&W photos in Aurora 2018. So at this time I converted 3 photos with different exposure into B&W and exported them into Aurora HDR 2018.

Here is a final result.
