photo editing effect

Question

what is that effect that makes it look like a camera was rotated 20 degrees or so while taking the shot? it makes it kind of rounded at the edges, like this:

Answer 1

Looks like a radial blur. In photoshop you'd select Filter > Blur > Radial Blur and select the "Spin" option (as opposed to "Zoom").

Answer 2

Radial blur.

It's available in most of photo editing software.

Answer 3

To produce that image, it looks like a radial blur has been overlaid on top of the original image with partial transparency so that you still see the sharp details through the blur.

1. Duplicate the current layer
2. Set the new layer to 50% opacity
3. Add radial blur (a type of motion blur) to top layer

A radial blur on its own would be blurry at the corners, but in the above example it's still possible to read "search here" on the top right or "Canada College" on the top left.
