Get the toy-town effect in your pictures
Duplicate the Background layer (Cmd/ Ctrl+J), go to Filter>Blur>Gaussian Blur and set Radius to 7 pixels. Add a layer mask to this layer. Locate the Gradient tool (G) and set the Foreground colour to black. In the Options bar, set it to Reflected and tick Transparency.
Click and drag a short gradient outward from the subject you want to keep sharp. As the gradient is a reflected one, it will affect both sides from the point you click and drag. The edges of the image should blur, leaving just the centre clear.
Press Cmd/Ctrl+J to duplicate this layer and effectively double the intensity of the effect. Add a new Hue/Saturation adjustment layer (Layer>New Adjustment Layer) and boost the Saturation up to +25 to give the effect a good injection of colour.
