Hi Gert,
yes it is supposed to remove LCA, but in the end it also worked for
people removing light TCA (of course it wasn't specifically made to do
that and shouldn't be optimized for that).
The issues are still:
- processing speed (but maybe okay, opencl code still needs to be
written as soon as
Thanks for the response. Do you mean with defringing, removing purple edges
and longitudinal ca?

Has anyone had a chance to have a look at this? If this is looks
decent I'd go ahead and:
- Try and get a comprehensive set of RAW files from multiple camera
models either by asking users for them or someone that already has a
large set of samples (dpreview/lensrentals/etc)
- Ask you guys for a se

The artifacts were due to the sse code

Sure, when I post directly to a list, I read the list.

I don't know whether you read the list, so I CC'ed you.

Here is an example of the distorsion values

I would guess something like fishtanks (I guess you mean just
photographing into a fishtank from the outside?) m

In the last days I saw a few updates of translations in the master branch of
darktable. Please also update the translations in the branch "darktable-14x"
since only that one will be released!

I totally agree on that. But it does not mean that we should cripple
darktable to do only the common cases. particular for exceptional cases CA
correction is even more important. What polynomials
