ART (the software) news

Fix confirmed, thanks Alberto!

Won’t it be useful to implement capture sharpening (in combination with RL deconvolution) as simplified by Heckflosse ?

Hi,

Currently ART doesn’t have a specific “capture sharpening” tool, but since ART has a different pipe than RT, maybe the effect of the RL sharpening method in the “Detail” tab has a similar effect as capture sharpening (@agriggio will correct me). In addition, RL sharpening in ART only has 3 controls and one of these controls has a check box for auto radius calculation (and its code comes form the latest RT code).
Anyways, I just tried to compare the latest changes in RT’s capture sharpening and ART’s RL sharpening, and frankly the difference is quite small in my opinion (I did the tests on images from an x-trans sensor).

Here are 2 comparisons:

  1. Test scene:
    RT Capture sharpening (default settings):

ART RL sharpening default, except amount = 60

  1. Real scene:
    RT Capture sharpening (default settings)

ART RL sharpening default, except amount = 100

Thanks for your interest, that’s a good news. I really appreciate ART software. I downloaded the real scenes for comparison, and effectively both are indistinguishable. Could you provide the raw file so that i see what I am able to do ?

What @sguyader said is essentially correct. I have no plans of including a separate capture sharpening tool, but I have incorporated many of its ideas (with the fundamental help of @heckflosse – thanks!) in the standard RLD sharpening of ART. I think you should be able to get similar results with the two

I shared that raw file some time ago here: Trying to emulate Adobe's clarity in RawTherapee - #37 by sguyader

@sguyader
Thanks a lot. I realized that I am used to set too high values to radius parameters.

Just a quick question: are there regular Windows exes of ART posted somewhere?

I don’t think so, sorry. there is this

but I’m not sure it’s kept up-to-date. I can generate a Windows build from time to time if there’s some interest, but I don’t have the time/energy to set up a nightly build service…

Except periods when I am out home, here:

André’s builds: ART-W64NightlyBuilds/ – Keybase.pub

Edit: he was faster than me

Sorry, I wasn’t clear earlier. I’m looking for an installer package. Unless these nightly builds are easy to install. Are they? Can I just run the exe like a portable installation?

of course :man_facepalming:!
sorry, how could I forget about them?
I’ll edit the first post and add a link there!

@europlatus

Windows ART builds

The ART development builds are portable builds packaged as 7z archives.

Just unpack where you want and run art.exe or art-cli.exe

Enjoy

Perfect, thanks!

@gaaned92
Would it be possible to have from time to time an appimage of ART ?
Is this very different from a windows build ?
I am a bit afraid that this request is too much demanding.
Forget it if that is the case.

Ask @Carmelo_DrRaw.

I am unable to do that :frowning_face:

@Carmelo_DrRaw can you help?

@gaaned92 @srgmro sorgy for the late answer… I have started some work in this directi9n, but the app was crashing at start-up and I had no time to investigate further.
Let me have a look again with the current got head. I will report back here about my progresses.

I have also started setting up some automated win64 builds, but that’s not finished either.
