[GRASSLIST:9745] Re: real color landsat images

[Wolfgang Zillig]

Sorry for the late answer!

 I tried it again, but it seems that my idea on how the result has to 
look was a bit too realistic. My first try was with an area in Asia and 
it showed a lot of forrest and the resulting green did not look very 
natural. That was the reason for my mail. Now I tried with a region in 
Germany and the result looks better.

Thanks a lot for the constructive help!
