1)get a picture that you like. Landscape pictures work best.
This will be on the left side under the ink colors.
the line should start in the middle of the page if you want this effect
Remove the quickmask on the bottom left (the first button you clicked)
sorry the text is hard to read. The next step is to click on the filters in the menu bar and go to blur.When you are in the blur section (drop down list) click on the lens blur. When your here you have to hit the Invert button or it won't work. Then after tat you can play around with the blur to where you like it.
to make it toy like you can play with the saturation of the picture. The more saturated the more fake it looks.
I hope you have fun playing around with this I did :)
