1. Load the photoYes, you are right, this fruit photo is not very dynamic, and no zoomeffect will make an action photo out of it, but it is perfect to illustratethe concept by highlighting the middle fruit. The procedure belowcan be used to enhance action-packed shots (say, of car ormotorcycle races, skateboard competitions), or even portraits.If we applied zoom blur to the picture, the whole of it would becomeblurred. Our first task is to select the area we want to leave sharp,i.e., the main theme.
2. In the focusIn this case, this is the fruit in the middle. Of course, you can selectany element in a picture, and dont have to keep to the middle.Select Elliptical Marquee from the Tools palette (or press M). If itsnot the active one, click the icon and hold the mouse button presseduntil you can select it from the dropdown.Draw a selection around the main theme and be sure to leaveenough space on the sides.
3. Polishing the selectionWe have a small task left with the selection. First, we have to blurits edges for a soft transition. Right-click inside the selection, andselect Feather from the dropdown. We set a 30-pixel soft edge onthe dialog that is displayed, as the image is rather small. For high-resolution images, you can safely use a value from 50 to 150pixels.Second, click Select Inverse from the same context menu. Untilnow, the main theme was selected. After inverting, the surroundingareas are. This is what we need, as they are to be blurred.4. ZoomedNow we can apply the zoom blur effect by clickingFilter/Blur/Radial Blur. The Amount slider specifies blur strength.A value of 10 to 15 should be enough.Select Zoom under Blur Method. Spin makes the picture movehorizontally, while Zoom pulls it towards the corners. UnderQuality, you have different options. Even if it is the slowest, youshould choose Best.
5. An action-packed fruitWhen youre ready, press Ctrl+D to cancel the selection. The resultwill be something like this. The main topic is highlighted much moreeffectively, and the zoom blur lends some dynamics to the photo. Asthe effect is even better with pictures showing real movement, grabsome and try it!
