Hmmm ja wiem gdzie mozna zrobic jako tako samoloty z góry. Mianowicie na Radiowej jest hangar WAT-u i przed nim stoi troche pomocy dydaktycznych, mozesz wejsc do pobliskiego bloku i z klatki schodowej cos próbowac zrobic
Sure! showed me this tutorial: [link] - it's very simple and it works. Also you might find useful this: [link] between photos are lots of tutorials and advices. I think that most important is to have good photo - it should show some objects from far perspective. The best are photos shot from some high places, but if you browse shashing magazine link you'll find that not only. If you have more questions go ahead I found this technique quite recently but it's always easier when two persons are thinking on one problem.
And yeah considering that these lenses are imho only toys the prices are outrages.
