Holding back, also known as pull processing, is a photographic technique where the development time of a film is reduced. This is typically done when the film has received increased exposure in the camera, helping to control contrast and avoid overly dense negatives.
By using holding back, photographers can manage highlight detail and achieve more balanced images, especially in high-contrast lighting conditions. Understanding this technique is essential for those working in traditional film photography to maintain control over exposure and tonal range.
