Image masking is a sophisticated technique used to isolate specific parts of an image while leaving the rest untouched.  Imagine creating an invisible layer over your image that selectively reveals or conceals certain areas.  This is essentially what image masking does.

 This versatile technique is widely used in photo editing for tasks like:  

Background removal: Isolating the subject to replace or change the background.  

Transparency creation: Making parts of an image see-through for overlay effects.

Special effects: Applying effects selectively to specific areas of an image.  

Whether you're a professional photographer or a hobbyist, image masking is a powerful tool for achieving professional-looking results.
