Turning an image into a Silhouette in Illustrator is an easy process and can be done with a few simple steps. First, it is important to open the image in Illustrator. This can be done by going to File > Open, and selecting the image from the file browser. Once the image is open, select all of the objects that make up the image by pressing Command+A (Ctrl+A on Windows).
Now go to Object > Live Trace > Tracing Options. In the Tracing Options, select either Black and White Logo or High Fidelity Photo depending on what type of Silhouette you want to create. Black and White Logo will produce a more stylized look while High Fidelity Photo will provide a more realistic look.
After you have chosen your tracing option, hit Trace and then Expand in order to turn your selection into vector shapes. This can be done by going to Object > Live Trace > Expand.
Now that your selection has been turned into vector shapes, you can delete any unwanted parts of the image or adjust them as needed. When you are satisfied with how your Silhouette looks, it is time to save it as an .eps file for use in other programs or for printing.
Finally, select all of your Silhouette shapes and then go to File > Export > Export As… Make sure that you save it as an .eps file so that it can be used elsewhere without losing quality.
Conclusion: Creating a Silhouette in Adobe Illustrator is quite simple as long as you have a bit of patience and know-how. First open up the image you would like to turn into a Silhouette and then use Live Trace with either Black & White Logo or High Fidelity Photo tracing options before expanding those shapes into vectors. Finally export your Silhouette as an .eps file so that it is easily accessible for other programs or printing!
