Using the New Live Trace Feature in Illustrator CS2

If you want to trace something more complex, you can obtain the best results by opening the photo in Photoshop and removing the background and any areas you so not want to trace there first, before placing the image in Illustrator. Use any of your favorite selection methods or the extract filter to remove extraneous areas from the photo. If you want less colors to make a smaller vector file, try using the Posterize filter (Image > Adjustments > Posterize) to lower the number of colors in the image before placing the photo in Illustrator.
