For some time now I have been wondering how some applications, notably Photoshop, manage to show a colour managed image almost instantaneously.
Photoshop uses lots of tricks. For example, it hardly ever shows you the actual image. Photoshop shows an image which closely approximates the way the actual image looks. Using various storage and display tricks, only a small amount of data needs to be manipulated for viewing on your display. Code that needs to be super fast is written in hand-optimized assembly for your specific processor type. That is why Photoshop is so expensive.
