How to take your picture: 

• Sit in front of your monitor.
• Look directly into the activated object.
• Push  "Take Photo" - below with your  cursor/mouse. 

• Don't forget to smile at the "camera." 
  Because this is a beta-version (trial version) you won't see any change of the "camera." But the picture will be shot the very sec. you activate the button!

• Click Take Photo when ready!
