Image retouching work

With Gimp, do an edit to any image you have. You will have to send two files:
  • the .xcf file from Gimp (or the equivalent program)
  • a text document explaining the process that has been followed: the tools used and all the intermediate images. Notice that every intermediate image generated during the work can be saved (with a screenshot, for example) using the Undo History menu; but once the work is saved, this History is lost (but layers are saved).


deadline: 29 February 2016
