Add an exciting effect to images with the Radial Blur filter
When using this filter, we need to create a duplicate of the Background layer. You’ll notice that this layer is locked (indicated with a padlock symbol in the palette), which stops it from being edited. But by going to the Layer menu and to Duplicate Layer, you can create an editable version above this locked one.
Find the Quick Selection tool in the Toolbar. To use the Quick Selection tool, tick the Auto-Enhance option at the top of the screen and click and drag a selection over your main subject.
When using the Quick Selection tool, you may see some areas of the selection overflow into the background. Hold the Alt/Opt key and click over these extraneous parts to remove them. By pressing Q, you can view the selection Quick Mask mode, so you know just how well it has gone.
When you have selected your main subject, go to the Select menu and down to Inverse. The shortcut for this is Ctrl/Cmd+Shift+I. This flips the selection from the main subject to the background, making it the active area. This is indicated by the marching ants around the edge.
In your Layers palette, click on the Add Layer Mask button at the bottom. You’ll now see a white and black mask appear on the layer. This has used the selection to hide parts of the image. Notice how the car is shown in black (hidden) and the background is in white (revealed).
At the moment the mask is the highlighted thumbnail. Click on the image’s thumbnail next to this to edit the contents and not the mask. Head to Filter menu and go down to Blur>Radial Blur. Set the Amount to 30 and the Blur Method to Zoom. Hit OK to see how your image has been affected by the filter.
There may be an area in your image that hasn’t been blurred but should be. You’ll need to click back on the layer mask thumbnail on its layer. Select the Eraser tool and zoom in on this area (press Ctrl/Cmd and +). By erasing the area that was missed out in the initial selection process, the blur effect can show through.
