Thanks for this Rhakios. I do already have mine set to high and as you say it does help a bit but still leaves the quality a bit disappointing. Whilst I like the simplicity of gnome photo apps that's not much consolation for inferior rendering of the photos.
I do quite like Digikam running under cinnamon, but the help tips are unreadable since the text is white set against a light yellow background. I think that I may need to alter the 'theme' setting by rejecting the default and clicking on configuration but nothing happens - presumably because its not installed on a full kDE setup. I'll wait until Clem releases Mint 13.04 KDE and try that. I do like Mint!
