<font face="Georgia">Dear Paul and Manfred, <br>
thanks for you interest. It works. <br>
<br>
According to your indications, I've applied a greyscale
equalisation to each band (using r.colors) previous to the band
combination. And the result is perfect.<br>
<br>
Thanks, <br>
<br>

<div>Hi Josep,<br>
<br>
</div>
The images probably need a 'Histogram Stretch' using
'r.colors' use the 'grey' (color) and tick Histogram Stretch'
but make sure you set 'g.region' to the full image first
otherwise it wont work.<br>

all,<br>
I'm working with r.composite to create a natural color
band combination using Landsat 8 image. The result is a
very dark image, so I would like to know if there's any
way to improve it. I'm using GRASS 6.X and also GRASS 7.
<br>
<br>
Thanks in advance, <br>
