I have tried to make the inside neutral not disturbing the blue church

Iâd like to improve the luminance clipping method in QRP. But according to Rawtherapee and darktable, the models they use a different.
Letâs assume the upper threshold is U, the lower threshold is L
Software | Shadow | Highlight |
---|---|---|
Rawtherapee | R < L and G < L and B < L | R > U or G > U or B > U |
darktable | same as Rawtherapee | R > U and G > U and B > U |
Which one is used mostly? Or maybe I shall implement both?
This is great
Reminds me a lot of Edward Hopperâs paintings.
Thanks for sharing all your different interpretations.
To start with, the church is illuminated by a very strong blue light, and @Rajkhandâs gets closer to it, although it lacks the purple accent present in mine. Next time, maybe I follow @paulmatthâs advice, or ask the priest to shutdown the lights for a while
As for the interior, although the street lights (tungsten?) spread a strong yellowish tint, I think I failed it in my edit. Last night I got back to the scene and the interior is not as yellow, dark and flat as in my edit, so I would stay somewhere between @Rajkhandâs and @paulmatthâs, if weâre trying to go the realistic depict way.
In the end, when I thought I was mastering raw editing, I realize that I have to get back to Introductory Edit Class again . Thatâs fine, a sign that things evolve.
Iâm not sure if âmastering raw editingâ exists, as raw editing always involves interpretation and personal taste - and monitors!
Be happy that things evolve for you, itâs always good to learn new things or to do existing things (your raw skills) better.
I was trying to change the annoying purple hue into something more yellow-ish in RT, but failed miserably!

Unless you want an artistic depiction, purple-blue is what that light looks like at night, more a less like my edit.
For reference, I took this minutes ago while walking the dog (cheap smartphone). They left one of the bulbs turned on, it might give a clue to what the hue might look like (look at the bulb borders)
Oh sorry, I thought it comes from the difference in colour temperature between inside the bar and church illumination
Do they use blue tinted LED light?
No need for sorry, after all, playraw is a free style territory.
As for the type of bulb, I donât know nothing about types (tried to google but couldnât determine for sure what type is this one). One thing is certain: the hue is strong purple-blue at night.
Nice edits, @Zbyma72age , very clear, although youâve eliminated the purple blue church hue. (which is probably the right decision aesthetics wise)
I canât speak for Ingo or any RT code, in dt the âhighlights reconstructionâ is clearly a weaker point. The clip algorithms works ok in many cases (at least i think so) but itâs definitely not reconstructing. The âreconstruct colorâ is very prone to generating artefacts.
I have just started a fresh and âclean roomâ implementation for a hopefully much better color-propagating algorithm, letâs see. (Iâll give you a hint if there is something noteworthy)
About your question in an exact way, i donât know about the history of the RT & dt algos and have no strong opinion on any advantage.
Thanks, @hannoschwalm I should have been more specific, sorry.
The point is the new culling app @qdwang is building (QuickRawPicker, see this thread), where I found inconsistencies between QRPâs raw clipping indicator and dtâs. Itâs not about highlight recovery, just the clipping overlay in both software.
EDIT: I think @qdwang is trying to change his code to match dt, but he noticed that dt determines clipping different from RawTherapee, so he asked which way I suggest him to go (but Iâm not talking for him, just what I think is going on)

a bit darker, it is night after all
