Well the result is perfect.
3 repositioning to be exactly the right place. You have beautiful focus to target the starting point, the film is a little shifted sideways or diagonally (even if it is next to nothing, well it shows!).
So the 3rd shot on goal, depositing the film slowly, he hunts alone bubbles and the result is impeccable.
No pb sensation, the finger slides well, the screen is very responsive ...
