Registration marks are small crosshairs or symbols placed on film, paper, or digital layers to help align multiple exposures or layers accurately. These marks ensure that each layer lines up perfectly, preventing misalignment, blurring, or color shifts when combining images.
Registration marks are widely used in film photography, printing, animation, and multi-exposure techniques. By referencing these marks, photographers and printers can maintain precise alignment across multiple frames or layers, achieving sharp, professional-quality results every time.
