Background Removing

• Use the "magic scissor" to select the outline
• Add and adjust points to get a clean outline
• [SHIFT] + click into the outline -> converts into selection
• Check selection with [SHIFT] + [Q]
• Correct selection:
  • Choose pure black and white as colors
  • Select brush tool: Hardness 100, Deckkraft 100
  • Or for a clean edge use the pencil tool
  • Size 20 is a good starting point for the tool size
  • Zoom in with [SHIFT] and mouswheel
  • Black draws things you don't want to select
  • Hit [x] to switch between black and white
  • Draw a nice outline
• Save selection:
  • To avoid painful loosing of selection you can save it:
    Menu -> Selection -> save in channel
• Remove background:
  • Invert selection with [STRG]-[i]

  • Or  copy it with [STRG]-[c] and paste it as a new layer
