    Default How to do a centre focus effect in PS?

    Anyone care to share your workflow for doing a center focus effect, ie, the subject at the centre of the picture is sharp and as you go towards the edge of the picture it gets more and more soft. This effect is achieved traditionally and optically with a centre focus filter.

    Togu?

    Er... something like this?

    This is my flow, a short one indeed,

    1. Use the Elliptical Marquee tool to make a circular selection. (For this case, the area where you want to focus)
    2. Select Feather from the Select Menu, type in a value ( I used 20 for this example. If you prefer more gradual softening on the selection edge, use a bigger value ).
    3. Select Inverse from the Select Menu.
    4. Apply Gaussian Blur filter, ( I used 10 for the radius )
    5. Flatten the image.
    6. Post!


    Hope this helps.

    My preferred way is to create a new layer and apply Gaussian blur to it.

    Then create a layer mask and use the gradient tool (radial gradient) to make the centre sharp and the surrounding blur. This provide better control because you can decide exactly how gradual you want the peripheral blur to be.

    That's a better flow.
