Re: [darktable-user] Correcting lens distortion manually

[Marie-Noëlle Augendre]

Thanks for your answer.

There is no name in the image information module, just (65535) but the
camera name is OK (and it is a non-removable lens). So what is the
procedure to have this fixed?

Anyway, a manual distortion correction module would be appreciated too, as
it can be used for artistic reasons; you might want to control the
distortion manually.
And it's also useful as new cameras are on the market almost every day.

First thing to do would be to report this to the appropriate upstream
project so that it gets fixed.
