As it's not my own photo, I'll take another one this afternoon (if the
weather is not too cloudy) and I will provide also information given by my
camera.

I think it's OK also because I set :
- DEM_size_x and DEM_size_z accordingly to the size of my DEM file,
- DEM_size_y is set to 65535 as I use 16bits PNG file.

Anyway, I will provide also DEM datafile and script I use.
