Alchemy Color

Thank you!

Hello everyone, I've invested months in making this free tutorial on how to achieve the best possible quality from color negative scans made at home with a digital camera without using plugins. https://github.com/alchemy-color/color-negative-inversion Based on my previous work with digital camera calibration and emulation, I decided to dive into negative film with a mission in mind: - What could be the most accurate way of capturing and inverting the color negative in the digital domain with simple means such as a DSLR and an iPad backlight? After extensive measurements and intensive testing, I developed a method that allowed me to scan and invert a Kodak Gold 200 photograph of a ColorChecker SG with a resulting average color similarity DeltaE of around 2.70. This exceptional value serves as a testament not only to the accuracy of the method but also to the virtues of color negative film in terms of its color accuracy. Thank you to Reddit users Aaron Buchler (u/Ab_film_92) for the inversion technique and Jack Whitaker (u/jrw01) for his informative article on scanner backlights. Both were fundamental in helping me understand where to go with my methods. Full disclaimer: Close to the end of the video, I promote a product created alongside this research. https://alchemycolor.com/film-emulation/. Color negative emulation is an innovative method if turning digital images into accurate facsimiles of film negatives and ingesting them into plugins such as Negative Lab Pro or FilmLab. Looking forward to hearing opinions and seeing your results. Cheers
