Open your photo in Photoshop.
Go to HUE & SATURATION and increase the saturation until the colors in your photo are bright, like toys.
Using either the circular marquee tool or the lasso tool, make a loose selection around the area of your photograph you wish to emphasize.
Go to SELECT>INVERSE
Go to SELECT>FEATHER and put in an amount of 20 pixels.
Go To FILTER>BLUR>GAUSSIAN BLUR and move the slider until the background of the photo is out of focus.
