ART feature requests and discussion

Ok, now I understand, thanks. However, this is what you wrote:

which I interpret as “empty file”. Next time, please try to be a bit more specific, thanks!

Yes sometimes my english is bad. The most important is that you understood the issue. It’s the most important. ^^

should be fixed now (hopefully :slight_smile:

I’ve just been playing around with it and I’m not seeing any difference to how it used to work. The Tonal map checkbox in the Tone Equalizer works independently of the False color mask, just like it has always done. Unless I haven’t understood properly…

Thanks ! :smile:

Ok I give up despite my frustration. On this occasion the translator is not my friend. :triumph:

Maybe record a screencast to show what problems you are facing? Ou vous pouvez m’envoyer un message privé pour expliquer le problème, peut-être je peux vous aider.

Hi Alberto @agriggio,

I’ve noticed that you updated input profile dcp for Nikon D750 recently, where did you get it?

I’ve been using Adobe Standard, but I’m not really happy with it - while it gives nice skin tones (for my taste), it also gives really unnatural aqua color tint to the sky.

And about dcp currently shipped with ART - I feel like it gives generally more warm colors for skin tones and more saturation (especially for green colors). I like the tones it gives, but 99% of the time I need to reduce WB temp by 200-300 and desaturate.

I generated it from color target shots taken under controlled conditions that you can find online… :slight_smile:
Should be decent but by no means perfect – if you have a color target and can contribute shots I will be happy to generate a new DCP

Btw, the wb bug should be fixed now

The profile is decent indeed, I’ll try stick to it now. Not sure if I can make better target shots, since I have never done this before. Maybe in future…

I’ve seen your fix, thank you! But for some reason there are no new nightly builds:

Well I pushed a couple of hours ago, we should let the night come at least :slight_smile:

Thanks!

Confirm, works correctly now :+1:

Thanks for the excellent fork! I tried ART out today for the first time and it feels really nice. Everything I tried worked as expected and felt responsive. (Using appimage of version 1.5.4 on Linux Mint 20).

I have two cropping related feature requests:

  1. A “Lights Out” mode like in Lightroom. It’s one of the features I miss from Lightroom every time I’m cropping. Dimming or blacking out the rest of the UI is very helpful.
  2. Possibility of changing the crop dragging direction, again like in Lightroom. This is much less important, but it just feels annoying when you have decades of muscle memory. It should be settable in preferences, like “Invert mouse Y-axis” in games.

Hi and welcome to the forum, @kirjis !

You may try keyboard shortcut ‘m’ to hide panels (press again to bring them back later) and ‘9’ to change/cycle background color. And also ‘F11’ to switch to full screen to additionally remove unrelated stuff from the screen. It’s not really a “Lights Out” mode of course, but I use it and find it sufficient for me. Maybe it will work for you as well.

In RawTherapee I was using F5 shortcut to open processed image in external viewer, but unfortunately it doesn’t work in ART.

Another thing that would make things more intuitive is to change the direction the power slider works. Especially should it be renamed to Midtones.

This actually depends on how you use it: if you want to add contrast (in combination with the pivot slider), then the current direction is the one that makes sense. Also, the slider has been renamed to midtones/gamma, and in that way the current direction still makes sense to me :slight_smile:

For my question, I have searched the various threads and documentation and can’t find an answer so I though I would ask. I am writing a script to use ART-cli to process Nikon .NEF files into 16 bit tiff files in preparation of making a panorama in Hugin. One “special thing” I want to do is to process all the .NEFs that will make up the panorama with the same white balance. So my idea is to convert the first .NEF then read its .arp file (which contains the “As Shot” white balance and extract that [White Balance] info and put that into another .arp file (say WB.arp) which I will use with a “-p WB.arp” when processing the remaining .NEF files, so that WB.arp will override the “As Shot” white balance in the remaining .NEF files and thus use the white balance of the first .NEF. My issue is that after ART-cli runs on the first “filename.NEF” the only output .arp it produces is “filename.tif.arp”, there is no “filename.NEF.arp” as you get when the same filename is processed in the GUI. Further the [White Balance] portion of the filename.tif.arp has a very different data for “Temperature” and “Green” compared to the filename.NEF.arp produced by the GUI. So my question is, how can I produce a “filename.NEF.arp” from ART-cli? (Hopefully that will contain the proper “Temperature” and “Green”.)

Additionally, in my testing, I think I found a bug in how ART-cli processes command line parameters. Specifially the “-V” option for verbose produces a bunch of initial output but then quickly exits without processing any files showing the usage output from the ART_print_help function in the code. I think this is because in main-cli.cc the dontLoadCache function does have code to process the “-V” option but the processLineParams function does not (I think it needs to be added as a “case” if only a “break”).

I know you want to use command line but would a selective paste of just the WB from the first file on to the rest no do the trick?? Copy Paste??

It would indeed work, that’s what I have been doing. :slight_smile: But I am an Engineer and my real life job is to automate things that are currently manual, so I just can’t help myself. :slight_smile:
