Here is a recent picture I took a bit before the sunset. A storm was just moving away from our place, and the sun was about to appear behind the clouds…
here is my interpretation:

I wanted to find something more abstract about this photograph, something inky and a little bit heavy.
I went for the pastel tones, in Darktable.
High drama in Filmulator, and then some dodging on the sunbeams in GIMP.
I love sun beans 
and clouds and challenges =)
I developed the raw in 2 steps with an app called froistycalleptskajumnenhirameater 
BTW very nice image, gud 4 redemptioning
PS
@Carmelo_DrRaw did you do your interpretation in PhF? That’s a such a palatable B&W ice cream you’ve got there mr ping
I neutralized the colors a bit with separate blackwhitepoint stretches for each channel, added a bit of overall contrast with a curve, then resized to 800x531 for a bit of poor-man’s denoise, then added another nlmeans denoise sigma=10
Apres-PP review shows some pinkish tint to the cloud shadows, I think I’ll leave it… 
Thanks for the invitation to play raw :-). I needed a break to actually try the software I’m working on. I pasted the jpg into MyPaint. I know, hardly “raw”, and MyPaint isn’t color managed yet (eek). At least I assigned my monitor profile and converted before uploading. . .
Anyway, the only interesting things I did was assign my brush color with illuminant “A” and work almost totally unsaturated to get that yellow color. I used a custom channel picker to pluck a few ciecam16 “lightness” values from the original photograph to get started, and adjusted my brush lightness with ciecam16 (JMh/JCh) adjusters that I’ve been adding. Here’s the interface so far (bottom block), somewhat inspired by GIMP’s LCH sliders. Although, I find just using the keyboard shortcuts much better for small adjustments. In retrospect I really should have used 2 layers, one for the sky and one for the clouds. . .
cHUE is just a static hue bar at lightness 50 and colorfulness/chroma 35. and cH, cS, and cV are the ciecam channels.
Interessting interpretations. Difficult to do somthing different. My try to be a little more colorfull …

All done in darktable.
Yes, that was a “fully PhF” edit. I have added a link to the .pfi file for reference.
LAB Color curves
Here is a photoflow attempt with crispy contrast flavour 
reminding you that every silver lining has a dark cloud associated with it.

EDIT: To avoid posterization in the photo, I had to save it at 100% quality. That is why the file size is not around 200KB but about 2 MB!
Reminds me of when a piece of dust/lint/spider gets briefly stuck on a movie film projection.
I remember when this was posted, I wanted to edit it but somehow I forgot about it. So I’m battling a cold today and started looking through the older Play Raws.
Couldn’t decide what to do but I liked how @sls141 accentuated the billowing of the cloud. Here is my take.
1. PhotoFlow → HL Mode (blend) → Linear Rec2020 (no clipping) → 32f
2. gmic → smooth (guided)
3 pnmclahe → enhance contrast
4. gmic → add contrast, brighten (curves) A → darken (gradients) → add contrast (curve) B → overlay A with B → brighten (curve) → sharpen (LoG) → resize
5. GIMP → heal spots
Zoom to 100% and enjoy!
