Dia-Positive in LrC entwickeln

Hallo!

Ich habe rund 50 Dia-Magazine/1000 Dia-Fotos "halbwegs" professionell (Nikon Z6 + Micro-Nikkor - JJC Diavorsatz) aus den 80er-Jahren digitalisiert. 90% der Dias wurden mit Kodachrome 64, einige mit Ektachrome 100/200 fotografiert.

Der Kodachrome 64 hatte den Ruf, extrem scharf, aber auch sehr "hart" zu sein. Das merkt man auch in LrC. Die digitalisierten Dias wirken in LrC zwar sehr scharf, aber vor allem in den dunklen Bildbereichen keinerlei Zeichnung und Details und alles sehr kalt. Dunkle Hemden/Jacken, braune Haare usw. sind nahezu schwarz. Viele Fotos wirken, als ob sie mit Blitz aufgenommen wurden.

Im Internet habe ich LrC-Presets gefunden, die aus "normalen" digitalen Fotos den "Kodachrome"-Effekt erzeugen.

Meine Frage: Gibt es auch Presets/Filter für LrC, die aus Kodachrome-Fotos ausgewogene Fotos erzeugen, die eher dem heutigen Standard entsprechen. Der automatische Weißabgleich in LrC liefert bei den Kodachrome Fotos keine zufriedenstellenden Ergebnisse.

Vielen Dank im Voraus und lg aus Wien,

Peter.

It's worth remembering that color transparencies only had a useful dynamic range of about 5 stops. A digital sensor, however, can capture up to 14 stops. So it's clear that the curve needs to be significantly modified, but it's also clear that it's well within the sensor's capabilities if you can just get the contrast curve right.

Yes, I remember Kodachrome very well 😉

 

Photographing color transparencies will always exaggerate contrast, and not the least with Kodachrome. You basically need to push the Shadows slider all the way up, and the Highlights slider all the way down. You will probably also need to reduce the Contrast slider quite a bit.

 

To retrieve as much shadow detail as possible, give it as much exposure as you can without clipping the highlights. Push it at far as you can. The good thing about transparencies is that there is detail there in the shadows if you just dig it out. But when the highlights burn out, they're gone.

 

If still not enough, you may need multiple exposures.
