The output sharpening seems to start working at 1791px long side. At 1790px long side, the exported files are identical, no matter which output sharpening I select.
Internally we've found the root cause of this issue. In a nutshell, images exported at less than 1/3 of their original size may not retain output sharpening / noise reduction settings. We'll fix this.
Sur Lightroom 5, si vous exportez des photos en dessous de 1200 pixels en bord large, avec des fichiers de 5d mkIII pris à 3200 iso ou plus, la réduction de bruit de couleur est désactivée à la sortie !
On LR5 if you export a picture taken with a 5d mkIII at 3200 iso or more, resized with less than 1200 pixels on the long edge, the color noise reduction is deactivated on the final output...
I'm quite sure many people would like to know if the fix will be in the normal release cycle, or earlier. - is there any good reason to keep that a secret? do you really not know?
This bug is also very annoying exporting web galleries, Cause there you always have picture sizes below 1/3 of the original size and any workaround (like exporting the affected pistures separately in LR4) causes a huge amount of extra-work.
It's original (uncropped) long dimension against ______ ?
That said, I've been having a hard time reproducing this issue - granted I've not done that much testing so far, is it expected to always happen (when resolution is low enough) or only sometimes?
Looks like nr is a "sometimes yes / sometimes no" kinda thing - is it the same for sharpening???
Would you mind clarifying - is it the output sharpening that's not working, or is the Lr dev sharpening being dropped? - thanks.
I can not reproduce erroneous nr nor sharpening (output nor Lr dev) behavior, so this problem clearly does not affect everyone / every-photo equally... - either that or I screwed up my testing. But I checked using Beyond Compare's image comparison - not a single image bit of difference.
Adobe Photoshop Lightroom is 5 problems in jpeg export. Sharpness and noise reduction are not applied at the output. Now, what to do!? Thus'm serious productivity problems.
This is a known issue that Adobe has promised to fix for the next release, with a time-frame of "weeks". The specifics are that sometimes LR doesn't apply NR or sharpening when the output image is less than 1/3 of the original size.
As far as what to do, another forum user has created a plug-in that uses another LR plug-in, Mogrify that you'll also need to get, to do the resizing and output sharpening after LR is used to do the NR and capture-sharpening at full-size.
