Zoom effects can be done through using a camera, but you can also get some interesting results when you use certain filters in Photoshop. This effect works great when used on photographs of moving objects, especially motor-sport photographs, but the effect can be just as stunning when used on still images.
1.) The first step is to choose your image you would like to work with, and then choose the elliptical marquee tool from the toolbox. Once you have chosen the tool you need to make a selection on your image, you can also hold down the spacebar to reposition the selection as you are drawing it.
2.) Now, it’s important to feather the selection. If you don’t the effect will be too harsh and obvious. The feather creates a soft edge and a smooth transition to the blurred areas. So you need to choose the options Select > Modify > Feather. Change the size of the feather radius depending on the resolution.
3.) Right now you have a selection around the center of the image, and you want to select everything but the center. Choose Select > Inverse and you should see the selection go around the edge of your page now.
4.) Next choose the options Filter > Blur > Radial Blur and choose Zoom as the method, select good for quality. Choose your amount to suit. For a heavier blur use 100. You might have to test it and undo a few times to get exactly what looks best on your image.
5.) Changing the feather and the blur amount will change the effect. Experiment with different shaped selections and different amounts of blur. In some cases you may want to apply the blur more than once.
