It's never too late to add the zoom during exposure look

How to emulate a classic shooting technique after the fact.
|While you can zoom during exposure if you have a DSLR and a zoom lens or with certain EVF cameras and compacts, many digital cameras don't let you zoom while the image is being recorded. Fortunately, Adobe Photoshop lets you add this fun effect after the fact.
Here's how to do it:
1. Create a duplicate layer in Photoshop;
2. Choose the Radial Blur filter placing the originating point where you wanted the zoom to start;
3. Use the Eraser tool on the new layer to remove areas you want to be clear and let the original image show through the background layer.
Using a non-zoomed photo of Tokyo's Akihabura section that was made with an exposure of 1/25 sec at f/22 and ISO 400, I applied a duplicate layer with Radial. Since the effect is different when used with a light background than a dark background, check out Create the illusion of Motion for a comparison. ©2003 Joe Farace
