[Play Raw] Positive slide from the sixties


(Gustavo Adolfo) #1

I’d like to know how would you process this old positive slide from the early sixties.


digitized tif:

This shot is from my father (flapido), and he used a Zeiss Ikon Contaflex.

What is the original film stock?

(Gustavo Adolfo) #4

Hmmm, I owe you that information, I tried to find the original here, but couldn’t find it. It is probably a common Kodak film (Ektachrome?), as far as I remember from my father’s talks about photography and films. He was an amateur and we were living in Africa (actually I wasn’t still born at the time of this picture), where the options were certainly scarce, speciailly at that time.


Hi Rei,

Here is my first attempt using Gimp/g’mic

Have fun!

Wow, after working on that file I realize that your salvaging of the colors is awesome!

I tried this foto too, and was not able to get a result as good as @gadolf image. And now @age image is even better.

This is a really nice pic, thanks for sharing! (I wish there were more portraits play raws, in fact). Here’s my take:


@agriggio How did you find the greens? :frowning:

I can’t show you a pp3, because I used a custom version of RT which is still a pre-alpha work in progress, but here’s a video that shows how I did it. Basically, I used the CDL controls to manipulate the R and B channels, looking more at the histogram than at the picture itself. I think it should be possible to use a CDL implementation in darktable and/or photoflow to obtain the same effect (though I didn’t try).

I second the sad emoticon… why can’t I see this video (I’m on Ubuntu 18.04)?

I think pixls.us messes up with the links somehow. It’s not the first time that it happens… anyway, here’s a direct link:

In my case (DT), besides setting up input profile to Adobe RGB (which already gave a boost to colors), what I think really changed the colors was the channel mixer tool and the new color balance. I also used the new filmic but it didn’t add much value, at least in my work flow.
This was done on Darktable 2.5.0 beta version

The site probably doesn’t have a streaming server, but this is only a guess.

Here is an attempt to restore the photo using RawTherapee dev 5.4-409-g99caa76f7

Then some color balance and healing in GIMP


Superb! Thank you!

My version was created with PhotoShop (adjusting histograms for R,G and B individually + white balance) and with NIK-collection.




@agriggio’s video, hopefully it works @gadolf << people can use the web inspector built in the browsers to scrape for the link ,-)

nope, on the long term doesn’t really work :frowning_face:

(Gustavo Adolfo) #19

Oh, no…

Just kiddin, good to see that @age, @agriggio and @shreedhar foss (& great!) versions don’t owe nothing to the PS one.

good tip, tkx. Waiting for yours.
