1. An image capture system for capturing first image data and for converting or transforming said first image data into second image data which can be subsequently used by a holographic printer to produce a hologram, said image capture system comprising: a rotatable camera having a lens having a first horizontal field of view and wherein said rotatable camera is arranged to produce first image data; a guide or rail along which said rotatable camera is moved or translated in use; translation means arranged to move or translate said rotatable camera along said guide or rail; rotation means arranged to rotate said rotatable camera whilst said camera moves or translates along said guide or rail; and image transformation means arranged to convert or transform said first image data into said second image data, wherein said second image data corresponds to image data that would be produced by an image capture system comprising a non-rotating camera which moves or translates along said guide or rail and wherein said non-rotating camera comprises a lens having a second horizontal field of view which is substantially greater than said first horizontal field of view, wherein said image transformation means is arranged to resize said first image data, to apply a pixel swap transformation to said resized image data and then to downsize said resized image data.
