I would just like to thank the developers for another great development of DT. After reading this post I see more capabilities in the lens correction module than I realised existed. It is time to read that section of the manual again. I also note that some cameras only have the option of lensfun while others have the choice of lensfun or embedded. Which would normally be the best option or does it vary between images?
Some cameras embed lens correction data supplied by lens manufacturer. For some from those cameras, that data has been deciphered and is offered as an option in lens correction module. How does a particular manufacturer come up with that data we can only guess. It is what is used by creating in-camera JPEGs.
Traditional option in lens correction module uses data from Lensfun database. That data is a collection of empirical distortion measurements from actual lens samples (recently some data was also added by extracting embedded correction data from RAW).
Which one of those correction options is better, is for you to judge. -- Šarūnas Burdulis math.dartmouth.edu/~sarunas · https://useplaintext.email ·
