Sharpening does not take effect on JPEG output

[ajlande]

Hi there, I'm new to AfterShot Pro, and I have a problem with getting sharpening to take effect on the JPEG output files. That is regardless if I use the built-in sharpening slider in the 'Standard' toolbox, or the Wavelet Sharpen plugin. The sharpening can be viewed in AfterShot, but the resulting JPEG is not affected. I use more or less the default "JPEG Full Size" batch output type when exporting JPEGs.

I have noticed that there is also a possibility for adding sharpening under post-processing in the batch output preset, but I don't understand how this relates to the sharpening via the standard slider or the Wavelet sharpen plugin..?

Please anyone enlighten me.

Are you comparing the result (JPG) and the preview at 100%?

I might not have done that all the time, but shouldn't the sharpening be visible on the JPEG even in reduced-size preview, at least to some degree? It is certainly in AfterShot when viewing 'Fit to window' size. (By the way, I primarily view the JPEG in digiKam.)

Can anybody explain to me the difference between the output sharpening option under post-processing in the batch output preset versus the other sharpening methods please?

Well, that is highly dependent on the application that performs the resizing and whether it performs any sharpening on top to counter the blurring effects of downsampling.
Aftershot for example uses a simpler algorithm, for JPGs than for the raw files.

In addition to digikam, try a few more viewers. EoG, XnView, gThums. You might be surprised (or not).

Sharpening in the queue is primarily useful to counter the effects of downscaling.

It seems you were right; when I viewed it in 100% in another editor (GIMP for instance), I could see the sharpening effect same as in AfterShot 100% view. It might be the "Reduced size preview" in digiKam that fooled me.

Thanks for the replies.
