           Summary: A 'film noir' plugin
           Product: digikamimageplugins
           Version: 0.9.0-beta1
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: SmallR2002 V8d Org


Version:           0.9.0-beta1 (using KDE KDE 3.5.4)
Installed from:    Debian testing/unstable Packages
OS:                Linux

By this I mean when most of a picture is in grey scale except one element of it. Examples:

http://www.deviantart.com/deviation/29566627/

I think this could be made faster if not totally automated, I have a few vague ideas how to do this, but I don't think any of them would work straight. Just an idea, I know it could be quite hard to make it totally automated.

Robert,

We need algorithms to process this job (:=)))) Study algorithms from scratch is not possible...

Well, if it's any help, here's how I'd do it in a generic image editor:
1 - Duplicate the basic layer
2 - Desaturate the top layer
3 - 'Cut holes in' the top layer so you can see the bits you want to be colour
Or:
1 - Duplicate the basic layer
2 - Desaturate the bottom layer
3 - 'Cut out' the bits you want to be colour

This should result in what you want, you may need a little 'feathering' at the edges or the odd touch of blur to make it perfect.

I hope this helps.

I think this is not task for single plugin but should be done as
introduction of layers and masks into *whole* Digikam. In this way you
could easily combine mask and black&white filter with all tone goodness
etc.

Arnd Baecker
How much of krita/gimp/... should be re-implemented in digikam in
the long run?
Could one use something like krita plug-ins in digikams image editor
to avoid code duplication?

Best, Arnd

digiKam image editor isn't krita. krita isn't digiKam image editor.

For any technical reason, digikam image plugins are different than krita.
plugins under digiKam existed before than krita is become mature.

Also, digiKam only support RGB color space in 8/16 bits color depth
(photograph). Krita run with more color spaces and more color depth. Krita is
not dedicaced to photograph only...

Forget definitivly a possible merge between krita and digiKam. It' not
possible. Trying to do it is the right way kill digiKam project.

gimp is a shame : no 16 bits color dpeth, no full support of metadata (exif,
makernotes, IPTC, XMP)! Gimp is not the better tool for a photograph.

krita sound like better !

Manipulation, yes, but limited and simple. This is not photoshop (:=)))

Simple, that is the point!
I don't know how I could achieve most of the digikam image plugins effect with
Krita/Gimp/Photoshop. The reason is that I have never tried, but I doubt I
can do it as easy and user friendly as in digikam: Limited choice of effects,
get a preview, tweak parameters, documentation, no thinking about layers or
any other concepts.

This is a different concept from Krita, and I think it is a different market
niche and fully justifies development.

Marcel
