Hello again @stefano.massari,

When I replied to you, I didn't realise that I was doing it in the tutorial 4 months ago. I don't know if you have seen it, but until yesterday the contest on architectural photography was open, to which I made reference in the previous message.

As I told you, I'm going to run it again today, although the success has been scarce with only one participant, I think that with a wider diffusion, there can be more participation.

Thanks for your interest.
