Reflection shadow means to create a mirror effect in an image. This is an important part of an image to look real in the proper situation. When creating Reflection shadows the image editor must be careful of light, darkness, the position of the shadow, etc. Reflection shadow makes images look more realistic and therefore, people will like it more than artificial-looking images. Reflection shadow is also called a glass mirror effect because it makes the objects in the images look like they are positioned on a glass surface and thus the reflection.
