Smart objects are a great way to add functionality to your photos without having to create separate files for each object. However, there are a few things you should keep in mind when using smart objects in Photoshop. First, smart objects can cause performance issues if used too often. If you’re only using them occasionally, don’t bother creating them in the first place. Second, be sure to disable the “smart object check box” on the “Photo Tools” tab before saving your photo. This will prevent Photoshop from automatically creating smart objects for you.
