I think the answer os in chain83 post here
https://www.reddit.com/r/postprocessing/comments/38vdao/how_does_everyone_sharpen_their_photos/

According to that, you're suggesting to also apply input sharpening

Thanks for the tip anyway.

For the best results you might want to consider sharpening in the raw
processor as well. :)

I tried RawTherapee and, together with the new 16-bit Gimp, I can say I found an
excellent replacement for PS.

Just as an example, I could manage to develop the raw image below the way I
would do with PS. I didn't loose much time in the tonal settings, but I was
curious to see if I could enhance the image regarding sharpness and noise. I
think I could.

I did the basics in RawTherapee then opened it in Gimp, where I applied the
smart sharpening method proposed by this fellow that I don't know the name
(http://gimpguru.org/Tutorials/SmartSharpening2/).

Since I'm shooting with an old and humble Canon Powershot A3100 running CHDK,
from where I'm able to get raw images, I can now say that I'm 100% GNU,

EDIT: The picture I shoot is no master piece, but shooting in raw and having a
good raw developer allowed me to recover details from the big white clouds,
something that on the original jpg shows as blown up white.

Gimp 2.8.x is 8 bit only. Wait for Gimp 2.10 or use the development version Gimp
2.9.x

For 'buntu and derivatives this is easily installed using a PPA. see

https://launchpad.net/~otto-kesselgulasch/+archive/ubuntu/gimp-edge

Updates frequently but is quite stable and usable. This will replace the
existing Gimp 2.8.16 installation.

It is possible to run both if the 2.9 is a 'portable' application. There are a
few around.

Search for appimage. There is a 2.9.3 here that should work in most linux
https://bintray.com/probono/AppImages/  and
https://bintray.com/probono/AppImages/GIMP

I keep an up-to-date 2.9.5 assembled in 'buntu 16.04 that should work in your
installation. Nothing guaranteed though. see

http://www.gimp-forum.net/Thread-Portable-Gimp-2-9-5-for-linux

Used to be a fan of photivo, but development seems to have stalled in 2015. The
gimp plugin stopped working for me. There are other tools, RawTherapapee for
example. If you have photivo from the dhor/myway PPA it is there for
installation.

example in kubuntu 16.04 http://i.imgur.com/tbPx1QP.jpg (but using nUFRaW)

It was the pt..something plugin in Photivio that gave problems, Quite a while
since I last used it.

But stick with Photivo, save as a 16 bit tiff, then open with Gimp 2.9.5

For RawTherapee, use this PPA to get the latest version 5

https://launchpad.net/~dhor/+archive/ubuntu/myway  It is worth enabling anyway,
lots of good stuff there.

RawTherapee will send to Gimp but for a portable Gimp you will need to put the
Gimp location in the RawTherapee preferences. example:

Truthfully, a bit over the top for me and my requirements. The place for

[Gimp-user] 16-bit: Photivo and Gimp

[oneaty]

Hi,

I have Gimp 2.8.16 (Ubuntu 16.04) and I'm trying to edit a 16-bit image the
following way:

1 - Import DNG file into Photivo;
2 - Make adjustments
3 - Open the resulting image in Gimp
4 - Save tiff file

When I edit the Gimp resulting tif file with mediainfo, it says it is a 8-bit
image.

How can I edit and save 16-bit images.

Wow, great information, thanks!

As for Photivo Gimp plugin you referred to, is it the code that allows the "Send
image to external editor" function?

I'll give a try with RawTherapee, but Photivo, gave me the best results out of
the box, besides offering a ton of options if I want to go further in post
production...

Once more, thanks for the great information
