Follow the instructions
Install on your smartphone the CamViz application and run it.
Press (+) / new record - the camera would get turned on - bring it over the QR-code of the card. A red button for recording will appear when the application recognizes the code.
Set your smartphone over the postcard so, that the camera captures the drawing area. The smartphone should be fixed. Do not hold it in your hand, use a glass, a book or some other objects nearby.
Press the record button and start drawing. Write only in the frame for drawing!
Take a pen with colorful ink or a felt-tip pen (do not use pale colored pencils).
When you finish your painting press stop and wait, while CamViz transforms your creation into a cartoon.
