Thank you Davi, i don't know yet how to set horizontal line, i know how to add control point manually. before to bore you with silly questions, can i ask if there is one or more video explaining Hugin advanced mode? if any of you would like to teach me, we can deal for a price and a lesson based on the procedure to obtain something better than what i did. a kind of pratical recorded video while merging my pictures. i would like to learn to make there shots without tripod even because i m a hobbist so it's difficult for me to bring tripod everytime expecially when i travel with low cost company :-D any help is appreciated Ninni Il giorno sabato 10 maggio 2025 alle 17:29:08 UTC+2 [email protected] ha scritto:
