Methods and apparatus for providing simultaneous, non-destructive blur patterns in an interactive environment. A blur module may render physically-realistic, spatially-varying blurs in digital images while at the same time giving users the flexibility to produce creative blur effects. The blur module may provide different types of blur patterns, including field blur, iris blur, and tilt-shift blur, all of which are available in a given session. Each different blur pattern can be combined with one or more of the other blur patterns non-destructively. Each blur pattern has a corresponding on-canvas user interface element or elements that can be manipulated for a live preview. A bokeh technique may be provided to create bokeh effects in digital images by simulating bokeh in the resultant blurred image. A selection bleed technique may be provided that allows the user to control bleeding at the edges of selections for any of the blur patterns.
