• 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 click the take photo link!  
  TAKE PHOTO  

Don't move, while the "camera" is working, but look at the twinkling spots in the lens.
