Morphing is a special effect used in motion pictures, animations, and graphics that changes one image or shape into another through a seamless transition. It is a technique that involves using a computer to make an image appear to change shape or change into something else. Morphing is mostly known as a visual effects technique in the film industry, but it is also used in other mediums such as animation and 3D modeling. Morphing was originally used by Hollywood directors and special effects teams in the late 1980s and early 90s, using powerful computers and pioneering software such as Gryphon Software Morph and Image Master. There are different approaches to morphing, and it has become more accessible and broadened as a technique as technology has evolved. Morphing is often confused with tweening, but they are different. Tweening is more about animation and adding movement, whereas morphing is a film industry technique used to create special effects. Morphing can be used to create a series of intermediary photos that show how an image changes from one to the next. Morphing is mostly used to add special effects to animation and motion films, and it can be used to combine two or more photos into one new picture.
