There are a few things you need to know before starting to vector in Photoshop. First, vectors can be created in any program, but they are more efficient and effective in Photoshop because of its vector-based design features. Second, vectors can be edited using the same tools as text, including selection, cloning, and opacity changes. Finally, it is important to keep in mind that vectors are not limited to simple shapes or designs; they can also be used for illustrations and logos.
