Megapixels 1.3.0 - colors feels wrong - hashfactory - 09-11-2021
Hi all,
I'm on Manjaro with Plasma Mobile on a pinephone rev 1.2. Just updated to the latest testing branch and got the Megapixels 1.3.0.
Since then colors in images feel way off.
I dug around a bit to find the difference in the postprocessing script.
The change seems to occur around line 76 of /usr/share/megapixels/postprocess.sh:
Code:
convert "$MAIN_PICTURE.$TIFF_EXT" -sharpen 0x1.0 -sigmoidal-contrast 6,50% "$TARGET_NAME.jpg"where Martijn added the "-sigmoidal-contrast 6,50%" argument.
The specific git commit (from a day ago) is linked here https://git.sr.ht/~martijnbraam/megapixels/commit/85819660a749f3e80638d0475fc7925893c480bd
Unfortunately I cannot understand his reasoning for this as it feels like the images look somewhat worse.
Here is a sample image converted from the raw .dng using the convert command without sigmoidal contrast (as in megapixels 1.2.0):
![[Image: IMG-sharpen.jpg]](http://dropoff.trido.fr/IMG-sharpen.jpg)
And here is the same .dng converted using the same arguments as used in 1.3.0:
![[Image: IMG-sharpen-sigmoidal.jpg]](http://dropoff.trido.fr/IMG-sharpen-sigmoidal.jpg)
If you want to revert the change, I was able to edit the postprocess.sh file and remove the new sigmoidal argument and things are back to normal.
Feel free to edit or mention how I should edit my post, this is my first post here!
Hope I was able to help someone!
