Just recently I tried the new Aurora HDR 19 program from Skylum. I had a few problems with it including crashing on large images - but that seems to have been my fault since I had a RamDrive created on startup which used 32GB of my 48GB RAM. And having 2 other VMs opened at the same time left me with very little RAM. Then I decided to test my usual HDR program - Easy HDR 3 - and 2 others - Aurora HDR 2019 and Oloneo HDR. I used a photo of a bird I took some time ago where I just missed focus on it. I cropped just the bird: Then put it through the 3 HDR programs - all at their default settings. This one is from Easy HDR 3 - and it can be seen that noise is quite prominent - a common problem with all HDR programs and which I usually cure by running it through Neat Image 8 to reduce or eliminate the noise. The next on is Oloneo HDR and as you can see the noise is vastly reduced even without using an external NR program: Finally Aurora HDR 2019 where the background noise is extremely well controlled: So it looks as if my usual HDR program has lost out - not really a surprise since it is now a few years old and the 2 newer ones - oloneo and Aurora HDR 2019 are brand new. If I was going to upgrade it, which I may well do then Aurora HDR 2019 looks like the choice - apart from the price of £92. But Aurora has a huge set of adjustments, including the ability to recover details in 3 different ways, fine, medium or large, all of which allow a load of tweaking to get the best results. I did find a website supposedly giving a £35 discount - which makes it a much better proposition. Both Aurora HDR 2019 and Oloneo HDR use AI which certainly does seem to be going from strength to strength. .
