Icon Image editing – An introduction to our work

Here you can see an example of image processing. The photographs are used with kind permission of WEMA Glauchau - Werkzeugmaschinenfabrik Glauchau GmbH.

  • Colour correction
  • Reduction of “fish-eye effects”
  • Reduction of converging lines and trimming
  • Retouching details not belonging to the machine
  • Retouching further details (e. g. dirt, paint blemishes, provisional labels)
  • Reduction to the image size required for the instruction manual (on the basis of 300 dpi); for this process, we use a program which preserves fine details

Subsequently, the photograph is inserted into the instruction manual and captioned by means of the word processor.
