[Bug 224241] New: film grain effect is not realistic

https://bugs.kde.org/show_bug.cgi?id=224241

           Summary: film grain effect is not realistic
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using KDE 4.3.4)
OS:                Linux
Installed from:    Ubuntu Packages

The film grain effect in Digikam's image editor is not realistic. It create a
grey picture but does not simulate grain. It would be nice to have a better
algorithm which adds different quantities of grain depending on lightness.

Julien,

There is already an entry about this problem. Solution is to use HSL color
space to add grainess. We continu to talk about at the common place #148540
