Drop shadow is a technique used to add depth and realism to images. It can be used in photos, illustrations, and videos. To use drop shadow, you will need to first create a basic outline of the image using a pencil or whiteboard. Then, you will need to add drop shadows to the outline using a black or white pencil. You can use any type of drop shadow for your image, but a simple one is called a “dashed line” shadow. To create a dashed line shadow, simply draw two lines parallel to each other and then shade them slightly darker than the rest of your image. This will create the droppedshadow effect.
