I have always wondered how films about space are made. I understand that this is either graphics or scenery, but how can you describe so effectively what is not yet fully understood.How to graphically depict something that he himself did not see (all sorts of satellite imagers manufacturer does not count), it is just such a complex, detailed and incredible work that it is very difficult to believe that this happens.I personally admire this. I would really like to know the opinion of knowledgeable people, how does this all happen from the inside.
