  1. 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

  2. @gt3rs I was all set on an R5C since they are great value these days and the 4K60p fine and cine OS are clutch but I found some R5II SRAW files online and it kind of blew me away. SRAW seems unique to the R5II, from what I understand its 8K downsampled 4K RAW however I think its line skipped. The greatest thing is the file sizes are tiny. On an R5C shooting RAW means 2500mbps files. Shooting 4K SRAW can get you files as low as 330mbps with RAW light and 750mbps files in Standard RAW. The quality is pretty outstanding, especially for the file size. This alone feels like a game changer but I see in your original post you warn that this mode has major moiré issues. Have you experimented any more with this? CLog2 being the other obvious benefit of R5ii but when shooting RAW on the R5C you can convert to CLog2 giving it similar rendering right? Just the workflow and file sizes is the obvious drawback versus Clog2 being available in compressed codecs.

  3. It's not filmmaking, he does gameshows. Anyway, this whole thread is a pile of crap and is locked so that it sinks into the gutter where the guy belongs, bye bye.
