As you would have never set a noise reduction! At first I thought it is up to me, because you Lightroom such an error does not trust, forget somewhere to put a wrong parameter hacking or similar. After a thorough search, I have found, however no such settings. So I searched the internet to see if anyone has this problem. Indeed! 1. Hit sharpness and noise reduction to missing export. Looking for a workaround I found several indications that there is none. Lightroom has just this mistake and you have to live for now until the release of 5.2 LR it.
The only way currently to export the images in full resolution and compress with a 2nd program to its desired resolution.
As if not bad enough, there are other problems that I do not eingehe now, but calling only briefly:
- Wrong image selection at publishing services
- Presets are not entered into the new Lightroom (Mac)
- Speed problems
- Cutting is not preserved (sporadically)
For additional information on the above-mentioned errors and what to do about it, I recommend the following page: [...]
one can only hope that a Lightroom 5.2 release will be there soon.
