[Bug 282464] New: Image optimization algoritm

[Rinus]

https://bugs.kde.org/show_bug.cgi?id=282464

           Summary: Image optimization algoritm
           Product: digikam
           Version: 2.1.1
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Image Editor
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           2.1.1 (using KDE 4.7.0)
OS:                Linux

If someone could do it it would be nice to have an algoritm implemented that is
able to guess all needed adjustments to make a picture looking optimal, so we
can  do this in batch cue. This is the only thing I like in elements, and the
only reason it is still on my pc. I have to admit, it does a great job. Can we
too, yes we can.

Algorithms are already implemented in Color Auto Correction tool. It already
exist in Batch Queue Manager.

It's not enough ?

I can not say how much I love that function! But could it be that the
software make a 80% right guess by itself and batch applies whatever is
needed for a specific picture. It is still my first step in workflow, to
do auto enhance in elements, that gives a realy good impression of the
potencial of the pictures and a good starting point to work in digikam.
If I had to do it by hand one picture after another... No problem when
we had to deal with scanned negatives, but thoose days we  shoot such an
awfull lot of pictures, we need automization.

This should take more in account then auto color, it should imply at least auto
level, auto curve and auto hue and saturation as well.

At the moment I experiment with this workflow speedup

 I add to the name
 _LC for local contrast
 _AL for auto level
 _AE for auto exposure

 ideally we need to have 6 variations
img.png
img_AL.png
img_AE.png
img_LC.png
img_LC_AL.png
img_LC_AE.png

after that we have to visually sort it out, that´s not a big prize taken the
fact the the usabillity score is very high.
Picking the right one is so much quicker than manually editing. I am doing
up to 1000 pictures per week.

Comment from Gilles:
The right question is how to do it in GUI.

My answer:
 I would be perfectly happy with an easy way out. Fead ONE batch to digikam and
find next morning all variation to select manually from.

digikam takes list of PEF and generates

img.png
img_AL.png
img_AE.png
img_LC.png

digikam changes in the batch cue all img.PEF to img_LC.png and generates

img_LC_AL.png
img_LC_AE.png

I wake up and do the rest.

regards,
Rinus
