How to Make Vector Files in Photoshop
Adobe Photoshop is a raster graphics program, which means it's designed to use bitmap, XY image grids to form pictures. While Photoshop isn't designed to edit vector files (Adobe Illustrator is the Creative Suite vector editor) you can use the Pen tool to create paths and shapes. Then, you can save the file as an EPS, which is the standard vector file format. When you open the file again in either Photoshop or a vector editor like Illustrator or CorelDRAW, you'll be able to edit the vector paths again.
Start Photoshop and click "File" and then "New."
Set a width, height, resolution and color mode. Enter a file name if you wish. Click "OK."
Click the "Pen" tool in the toolbox on the left-hand side of the screen. Use it just like a pen tool in a standard vector program: click once to set a point, click again and drag to define a line. Click the original point to close the shape. For further instruction on using the "Pen" tool, consult the link in the Resources section of this page. You can use other Photoshop tools to edit the raster image properties, but they will not translate into vector paths or fills.
Click "File" and "Save As" when you're done editing your vector paths. Under "Format," select "Photoshop EPS." Enter a file name and navigate to a save location. Click "Save."
