imho, halos are more coarse grained, while artifacts are more fine grained. But just my opinion of the wording of both…
I gave it the Filmulator treatment with maximum drama.
- Auto CA Correct 2
- Profiled Distortion on
- Exposure Compensation +1.5
- Reduced film area (to broaden the halos)
- Drama 100
- White Clipping Point 0.42
As far as the halo discussion goes, I apply it to both the handful-of-pixel halos some tonemapping algorithms create and to the hundreds-of-pixel halos that Filmulator makes.

First serious edit using RawTherapee. Bit of a steep learning curve and I’m not there yet, but I might be slightly in love…

Here is an attempt using essentially the LAB module of RT 5.8 with a little bit of Dehaze, Wavelet Final Touchup and Edge Sharpness thrown in. There was a huge green fringing on the cross. Removed it with the Defringe module.

Where is this building?
Here in Czech Republic there is a couple of churches of St John of Nepomuk, but this exact one is located in Prague (Praha 1 - Hradčany) and is also called as Military Church of St. John of Nepomuk (Vojenský kostel sv. Jana Nepomuckého in Czech language).

Although I have never been in the Czech Republic I already thought so, just wasn’t quite sure. I know that there are many John of Nepomuk churches in the Czech republic but there are also some elsewhere. I think I remembered this church subconsciously form a class at university. Well… time flies… some 20 years ago or so…
Ah… just looked it up: the architects were Christoph and Kilian Ignaz Dientzenhofer - quite important.

I may have gone a bit over the top, and you may spot a few halos.
(Over) processed in ART
Thanks for sharing!
Used tone equaliser, tone curves, local contast and delta E mask to darken sky

Hi Alberto, how to get your processing parameters from your jpeg files. I work of course with ART.
Thanks for the advice.

In principle, you just load them:
However, there was a bug causing an infinite loop. I have just fixed it, so you should use the latest version from master if you can…
Ok Alberto, I compiled the last version (1.5.3.25), but it crashes when opening a raw file.
Sorry
