I have posted a new blog post Scanning Color Negative Film
This post details how to scan and process a negative with a digital camera. I cover everything I have learned from testing and experimenting over the last few years.
I also include luts and scripts to help streamline the process.
The post focuses on adobe photoshop and its non-destructive adjustment layers (sorry gimp). But the process described can apply to other software including Rawtherapee’s film negative tool.
I hope that film photographers will find they can get better scans and that this post will be a useful resource for anyone scanning film.
I plan to add-to and improve this post over time. So feedback is appreciated.
I’m updating this post because I have since improved the original blog post for clarity, and better formatting.
I came to many of the same conclusions as the developers of Rawtherapee’s film negative tool, so my post may be helpful for anyone who wants to better understand how either process works.
I have also tested the process in Krita and I got it to work well with 16-bit-float and inverting using divide blend mode.
Thanks for providing this information.
I contemplate a negative scanning project next year upon planned retirement. A quick glance on your blog post informed me what that may entail if I’m to do it thoroughly.
(You also shattered one of my “lay” understandings regarding the linear/non-linear difference between film and digital sensors . Thank you!)
