[ArcheOS] R: Re: E-Foto Rectification problems

[luca]

Hi Alessandro,
thanks for reporting on gimp-lensfun. It looks an interesting plugin. 
Normally (in the way we work on the field) it is enougth the correction 
which e-foto does using the raster model done with GRASS, but this tool 
could be interesting for some "extreme" situations, like for people 
usign (for some reason) wide-angle lenses or "fish-eye". just some days 
ago i get an email about the rectification with e-foto of such kind of 
pictures.
Ciao e grazie
