Thanks for sharing. I have no sense for artistic merit but that one really evokes a wistful nostalgic feeling, for some reason. Evocative is always a nice achievement in a photograph.
It seems to me better vegetation should be possible with HDR, but i guess you're running into limitations with the N900 here.

Classic example of arbitrary Nokia decision making. Couldn't just fallback to the no brainer of tagging with lat/lon if network isn't accessible, could you Nokia?

is it maybe possible that someone creates a script that automaticly merges the photos? because the script above is great, but you'll still have to merge them on your pc.

i dont think that is possible because you dont just have to merge the photos, you have to change the gemma, exposure, saturation etc etc i dont think n900 will be able to handle that. what i think will be useful to have is a camera widget which would actually run this script automatically and take the pictures in RAW format. pictures, when converted to HDR, turn out to be really good if they are in RAW format. but where as the HDR merging is concerned, i believe it is best to leave it for the PC to do it.
(This is just my opinion)

just a reminder: a .sh file can do almost anything to your system. i personally wouldn't download & execute a sh-script from megauploads or similar source....
