I’ve just tried something. I’ve inherited a load of transparencies that date back as far as 1950ct. Most of the older transparencies have shifted colours due to age, storage and whatever other causes might exist. I wanted to see if I can use NLP’s internal process to improve the overall appearance of the transparencies. This is what I did - changed orientation and cropped to taste - adjusted WB and the RGB tone curve - created a virtual copy - inverted the RGB tone curve - launched NLP This is what I got: Left: Source image, Right: After using NLP ![test](https://canada1.discourse-cdn.com/flex029/uploads/negativelabpro/original/2X/1/1473e8558c3841f5f636787157966bc2b1a927f2.jpeg) Both images were not customized other than what I listed above. Further improvements can be made with the HSL and Color Grading tools. Here’s a quick upgrade: ![Bildschirmfoto 2020-11-30 um 14.50.56](https://canada1.discourse-cdn.com/flex029/uploads/negativelabpro/original/2X/d/db4e8ba4e1b6ee6ef38848ffd717843a83ba9f91.jpeg) Sky: HSL tool was used to change the saturation. Grass: Color Grading was used. ---

I logged in specifically to see whether NLP would be suitable for processing transparency scans. I’m currently embarking on digitising my late father’s vast archive, which consists of 2/3’s positives, 1/3 negatives. It’s good to know that NLP is a powerful tool for both. BUT… wouldn’t it be great if it wasn’t necessary to invert the image first? If we could select a “transparency” option? ---

That’s really good news. Thanks, Digitizer. ---

Just wonder if there’s any other information or additional user insights into improving transparencies. I have many to do, and the task is very difficult.
