It's even worse in the Picaros, where Wagg's camera just melts (compare p51, D3 & p52, D1)... The local temperature doesn't seem so hot in that jungle though, for we don't see anybody sweating!
Well spotted, Yamilah ! I've never seen that before, but yes, Wagg's camera does definitely seem to melt.
Congo is an unusual case, definitely - if it wasn't for Tintin cranking the handle on the side of it, it could just have been an old-fashioned box camera. It's odd that the bookcover has that detail on - it's present in the second black and white edition's cover too (the colour cover is essentially the same picture). Speaking of inaccuracies on covers,
Destination Moon has a rather funny one - not only is the jeep completely different to the one in the book itself, it also has no steering wheel ... puts a different slant on Calculus' driving without a license, I suppose !
RE the
Castafiore camera - I'm not sure why the notch was added, perhaps it's something to do with the process of telerecording and needs to hold another reel of film. Some information on the process can be found
here. What does the French edition refer to the filming as (page 31, panel A, the presenter) ?
