The final image was to be used on a Roll-up and therefore had to be extended to fit the format. The image was given a increase in contrast to make the most of what was not the most interesting of subject matters.
From the sketch a photographer was employed to create the image of the lady sitting at her desk monitoring the progress of the pumping station. The perspective of the water process plant was corrected and the sky extended. The images were superimposed and given both a light and dark effect which were later used in magazine ads and brochures.
