Why, some of them are very good //Edit azkay, I've just noticed, that your photos are affected by vignette (originally RAW's, probably?). While in first photo it nicely mix up with view itself (positive effect, that's why I haven't noticed it at first), on the second one, it seems not-so-beneficial. You may want to try FOSS program CornerFix (available for windows and MAC, not for linux sadly, as it relies on open but not free'ly licensed tools from adobe) - it is only one application that I know, which cleanly removes vignette from N900's RAWs, on RAW level itself. /Estel
