Some image transformation processes could be computed nearly-instantly. For example, the amount slider blends the before and after image using an adjustable ratio. Modern CPU-GPU combinations can handle this very quickly.

According to a user preference setting, some effects could be adjusted in real-time without having to release a mouse button.
Other that Amount control, this could be extended for example to color and gray curve controls, using Lookup Tables to accelerate color or gray transformations.
