[Play Raw] Positive slide from the sixties

Very good case for my color-neutralizer, in the color balance module of darktable. With auto-hue neutralization:

Then tweaked further to my taste:

To remove the mold, the best option I can think of is:

  1. Create an high-pass layer with a radius that matches the mold micelles
  2. Invert that layer
  3. Apply it in subtract mode
  4. Use a parametric masking centered on green
  5. Maybe use a brushed mask to isolate the mold from the grass

@Thomas_Do Thanks, that’s a pretty simple but highly effective solution! I used it on other scans with the same problem and it just works.

Here is another version using the latest [RT 5.5 RC1]. I used RGB curves, the Haze removal, Soft light, Film Simulation and Wavelet modules.

Hi @shreedhar,

I have compared this one with your last development, on Nov 21.
This one has more depth!

Have fun!

Yeah @Claes, I agree. I think the Haze Removal tool is very useful here.

I wonder if such strong magenta casts were standard for that film. Did people in the dark room regularly have to wrestle with such casts? Or is this the repercussion of time passing or?

Morning, Stefan!

Not that I remember :slight_smile: The films were developed using certain processes, like E-6, used for Ektachrome, Fujichrome and other slide (colour reversal) films, or K-14 for Kodachrome, and so on.

That is what I believe.

Have fun!

Me too. But I have other slides from the same time that still show superb, natural colors. When I brought them to editing, I couldn’t find anything left to do regarding tone mapping. My brother raised a question whether chemicals could react differently depending on the exposure values, for example, under exposed images would degrade faster and maybe present some color cast even from the beginning. Who knows.
Look at this one, from the same time:

EDIT: The Zeiss Contaflex that shot the girls picture is with the third guy from right, who happens to be my father.

Rawtherapee and GIMP, I tried to regain some detail in the shadows in the ditch.

@aka_andrew I can’t see the image, seems to be broken.


(andrew) #51

Seems to be there for me ?

Not for me. I also get nullxnull.
Edit: your new one I see.

I decided to go with B&W because I am not good with colours. Did minimal processing as comfortable. Removed some of the blemishes but not all of them for effect.

1. gmic → crop (1.5:1) → inpaint cracks → local contrast (guided) → norm → smoothstep (curve)
2. GIMP → heal (dark spots on face)
3. gmic → sharpen (LoG) → resize
