The solution here seems to be to only apply dithering to the two blueish-areas where the 8-bit colour banding is most apparent, these are the top left and middle bottom. This avoids applying noise to the whole image, whilst still solving the visible problem.
Otto: do we the vector-ise original 12-bit or 16-bit colour depth that we can work from? ** Description changed: Following on from bug #833990 for Ubuntu 11.10. Subtle adjustments that follow in line with the previous two releases, as quoted below: 'I have made subtle changes and introduced new light refractions. We can continue to add light streams and re-balance with each release - the landscape becomes gently lighter and brighter and gains in complexity to reflect our drive towards 12.04 :) IMHO as we move towards becoming more of a 'household' platform and with the great changes coming with Unity (launcher/dash) general users will get reassurance from the familiarity of the wallpaper and will also identify with it as part of our personality in new screenshots. This time I have re-balanced rather than just adding additional light streams and have introduced more warmth - it's the LTS after all ;) Included are two versions, the difference being 'new_wallpaper_final_full_size_noise02a.jpg' has noise added to counteract posterisation in the blends but it is a much larger file - I would of course prefer to use this one if at all possible. Despite the fact that these files are named 'new_wallpaper_final_full_size02a.jpg' and 'new_wallpaper_final_full_size_noise02a.jpg' please rename the final selection to 'warty-final-ubuntu.png' to be registered as the default wallpaper. + + See also bug #933562 (12.04 LTS community wallpapers), which should + ideally go up in the same upload. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/968399 Title: Incremental tweaks to default wallpaper for Ubuntu 12.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-wallpapers/+bug/968399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
