hi Asher and thank you very much for the interest. As always
I am not sure what the irregular vertical lines are but I suppose that, while moving, the lines get wavy - it is, by now, the way flash works - compromises when moving and stabilizing when stopps; another problem may be different kind of errors that may be my responsibility.
Instead of spending the time and gas to get 40 km from Barcelona, the real estate agent only navigates through the pictures and the customer gets an idea and knows it's worth the travel or not.
The real estate may be interested in such presentations and besides them, I had paying customers such as architects in different cities (that by seeing the panorama don't have to take the trip to visit the place) - so seeing the situation at a certain moment; also timelapse with the growing of the projects or different milestones can be imagined.
Another thing would be the presentation of the places where customers don't naturally have access: restaurants kitchens, hotels laundry, so the client may get an idea of the specific details such as observing eco-friendly washing machines with anti-alergic detergent and so on.
