I took a 5 shot bracket of a cityscape and am getting lots of ugly artifacts with the various light sources after HDR merge in Lightroom CC including white and red point light sources such as street lights and vehicle light sources. I'll attach some examples. Anyone know why this is happening and if there is a workaround?
After HDR Merge of 5 shots:
The Adobe Engineers recommend 3 shots with a 2 stop difference between each. I have done it a couple of times and have had no problems..
Some of those artifacts are moving car headlights, which will appear in different places in each bracket file.
Make sure 'Auto Align' is checked and try different Deghost Amount settings.
