Conversation

For the "very dull images" Q, can you please link to the section in the manual that explains about raw vs jpeg?

Did you have anything specific in mind? The only thing I could find about raw vs JPEG was the section linked by the existing previous question's answer (Why doesn't the raw image look like the JPEG). |
|
Yes, that's the one.

What would be the point in adding another link and having it in two successive answers, given that the manual section isn't addressing the camera's deliberate underexposure? |
|
Two successive answers in a row doesn't mean anything, this page is not end to end reading.
This FAQ groups well with that section. I'm not asking you to remove anything about the deliberate camera underexposure, but to add a related item.

I specifically chose "alternative" since that's the term everyone seems to use when reporting on DT or comparing to LR. |
|
I also prefer alternative as replacement is exactly what we fight against new users. Darktable is not a drop-in replacement, it is very different and yes it can be an alternative. That being said I'm not an English native speaker :) |
|
I made the change to the question so that the answer to the question is specifically about not being a replacement, but rather an alternative. Added a more explicit statement of this at the start of the answer. |
|
Thinking about it, I would keep the original question, and change the beginning of the answer:
I'm actually planning to completely rewrite that entry, since I was never truly happy with it. |

There was a problem hiding this comment.
We should not tell people to report stuff to lensfun. We should tell them how they can submit their lens if it is not supported, but often times it is exiv2 that doesn't map the lens name correctly (if the lens is supported by lensfun) and we don't want to burden them with those "bug reports".

There are some good things here that I really think should be merged. The section on dark images I think is good as-is. Linking to the manual directly doesn't make sense, I agree, but I would add Compression formats and SIGILL should also be merged. I'm working on rewriting the LR alternative entry, so that should not be merged. And I do think the Lensfun entry could use a complete rewrite, instead of just patching it up a bit. But it's still better than before, so I would merge it. |

Also (in separate commits if you want to cherry-pick) add a note about compression formats to the Q about unable to open, and change "Lightroom alternative" to "Lightroom replacement" as the latter is more accurate phrasing.
