 FAIR: Modern viewers often complain that the wires used to suspend  the Martian war machines are plainly visible throughout the film.  The film was originally shot in three strip Technicolor, with prints  made using a dye transfer process that resulted in very saturated  colors but a slight reduction in overall resolution. This reduction  in resolution "fuzzed out" the wires in original prints, making them  effectively invisible. Later prints were made in Eastman Color,  which uses a photographic process and yields sharper prints, but  here had the side effect of making the support and electric wires  plainly visible. (The models had electrical wires as the side pods  of the machines really lit up green and the "cobra heads" lit up as  well.) It is common practice in the film industry to take into  account what details will be visible when a print is projected so as  not to waste production time and money on details that will never  actually be visible to a viewing audience, especially in the areas  of effects and matte paintings. Thus the filmmakers never thought  the wires would be visible and in fact they werent until the first  Eastman Color prints of the film were struck in the late 1960s, and  they have become even more visible on modern video releases as there  is no dye sublimation resolution loss when making video masters from  the original negatives.
