RGB and CIR visualization

[Jaime Lopez Carvajal]

Hi Stefan,

Of course, I would like to visualize the image like this (attached image), 
that was obtained using ArcMap software, with the usual band order for True 
Color (RGB) and Composite Infrared (CIR) in remote sensing applications.
The tiff image that I loaded has 4 bands, so I would think that the order 
would be: band0(Red), band1(Green), band2(Blue), band3(Infrarred), 
so if I want to visualize the true color image, I would need to use this 
instruction:
TrueColor_img = img11[:,:,(0,1,2)] 

but as you can see, the obtained visualization is very different from 
natural color.

I hope this helps, Jaime
