P: Output Sharpening and Noise Reduction not working.

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.

See the reply in the merged thread just above for a link to the "LR5.0 Export AutoFix" plug-in: http://www.robcole.com/Rob/ProductsAn...

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.

After cropping, and since aspect ratio is preserved, either long dimension or short dimension can be used.

i.o.w.

long dim exported / long dim cropped < 1/3

or

short dim exported / short dim cropped < 1/3

This will fix it right up, no fuss / no muss...

Lr5.0 Export AutoFix

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.

Here's two workarounds for the meantime:

In cases when this bug bites (e.g. low-enough rez).

1. Use Lr/Mogrify (export without resizing in Lr's Image Sizing section, then downsize using Mogrify Resizing Options).
2. Use PreviewExporter.

hmm 1200 is *more* than 1/3 of 3200.

So, one dimension down, one to go.

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???

Rob

Long dimension. I don't know if it's before or after cropping.

Eric,

What exactly do you mean by "less than 1/3 their (original) size".

Are we talking "width x height", i.e. pixel count, or long dimension, or...

And is it "1/3 or less", or really "less than 1/3".

Thanks in advance,
Rob
