Two new photos from the filming of Tintin have surfaced.

This shot (reportedly) shows Jamie Bell with another, unidentified
actor and members of the crew. Snowy is simply a piece of cardboard
on the end of a broomstick and just there so that the actors have
something to react to when filming the scene.
Actually, that should be capturing, not filming, the scenes. There
is no film or even video involved in this process.
The strange, wet-suit style, costumes the actors are wearing are
covered with markers. These markers are tracked by sensors placed
all over the room and their location are precisely recorded
hundreds of times a second and stored to a computer. This data is
then used in the CGI animation process allowing the director to
create any style of image they want but based on the real movement
of actors.
There is a second photo over at As Aventuras De Tintim, a Brazilian
Tintin blog: EXCLUSIVO: Novas imagens do set de Tintim. I
cannot find these images anywhere in the mainstream yet so this is
a real scoop for them.
