How to Convert Film Negatives With Free Program - Darktable Negadoctor Tutorial 2020
I retain the film negatives of all my hard-copy photos. They are in good condition and well packed. If I can’t restore the faded photos tinted heavily with yellowish color I’ll scan their film negatives. I have done some tests before, scanning the film negatives on Samsung Galaxy S22 Ultra Mobile phone, using Samsung Galaxy Tablet as lightbox. Afterwards converted the digital negatives to digital positive on GIMP with “Invert”. It did a marvelous job.
I have >1,000 hard-copy photos to be converted to digital positive photos. It is not an easy job for me. Besides I have to adding description on all digital positive photos, such as date and place of their captures, name of persons on the photos etc.
I’m not going to print the digital positive photos but will create slideshows on them, adding background musics, subtitles, narrations, etc. I have long experience in creating slideshows running OpenShort, ShortCut etc.
On Internet search I found following YouTube video;
Darktable Newb :: Part 1 :: Getting Started :: Concepts and Basics
darktable NEWB :: Part 2 :: First Edits
darktable NEWB :: Part 3 :: More Modules, Masking and Denoise
They will be helpful to me because Darktable is completely new to me
