thanks, i will check out ansel-a. I guess applications for modifying the colour etc before taking a shot would be the most useful for the camera itself, if possible. Ill prob try a trial of photoshop or a similar pc app if I ever need it for any photos, its alot easier to modify on a monitor screen anyway, although trying make sure colours are true to the original is a harder process when youre back home without the original view to compare with, lol. thanks

update: I tried ansel-a! its far too slow to use with photos either the lack of memory on the n900 or because the prog is still early in development! not a bad app though
