A data-driven approach to film inversion

Hi everyone,
Over the last six months, I’ve dusted off my Pentax 67II, ditched the flatbed scanner and improved my negative scans using my digital camera.

I’ve read through the darktable documentation and experimented with different methods, and I’ve finally put together my data-driven approach to film inversion in this blog post.

It might sound like nonsense, but since I changed my approach from ‘I’m digitising a photograph’ to ‘I’m collecting and transforming data’, the final quality of the scans has improved dramatically.

Moving from adjusting sliders based on gut feeling to a precise technical approach has allowed me to extract from my negatives the images I’d been searching for for a long time.

I must also add that, throughout this process, the Lumix S5II has allowed me to capture the maximum amount of detail.

I don’t consider this the definitive article and for this reason I’d like to gather some feedback:

  • from the experts, I’d like to understand whether my approach makes sense, or if I’ve gone off the rails;
  • from the less experienced, whether the article is useful, whether it’s clear and wehter it has helped you achieve a better end result.

I’d also like to add a few photos of my setup: the ones I have were taken at different times and don’t really fit in with the rest of the article. I hope to take some over the weekend.

Thank you for your feedback!

You have developed a system that works well for you. It acts as a good guide to others. The only improvement I could suggest would be to include the raw file of the dog picture so the reader can follow along with the steps you show. This would then turn your blog into a useful tutorial if that is what you want to achieve. .

Thanks for the feedback! I’d meant to link to the original raw file, but in my rush to publish it, I forgot :frowning:

Hi,
Interesting post. I need to translate it to my language (FR) before I could use it efficiently and to adapt it to my usual software (ART).

Ciao

Hi @Terry,
I’ve taken your feedback on board and added a zip file containing the original raw.
I’ve also tried to explain more clearly how the corrections in the negadoctor module work.
Compared to darktable documentation, I’ve tried to provide a more practical interpretation.
