From Photoshop to GIMP

updated 2016.11

  • Quick Conclusion for Photo Retouch
    • for lack of adjustment layer, it is hurting the fast workflow for non-destructive photo retouch workflow
    • it has clone, and basic heal for 2nd layer retouch, but lack of quick spot heal and patch tool may slow down the retouch process a bit
  • Quick Conclusion for Graphic Design
    • lack of “mask unlinking feature” and “quick multiple layer selection” are slowing the arranging layout process
    • same, lack of adjustment layer is quick no no for fast multiple alternation version creation.
    • text is not able to keep editable after rotation or scale, and lost vector graphic information, which means big No No for graphic design.
  • Quick Conclusion for general usage for image editing
    • it has all the essential tools for non-professional graphic user to get the job done.
