Filter accessories such as step and adapter rings hold your filters allowing you to capture images with perfect contrastCONTRASTThe difference between areas of different brightness levels in a photograph: A high-contrast image has a greater difference between light and dark areas, whereas a low-contrast image has a narrow range of tones. Contrast is used to direct a viewer’s attention to a photographer’s subject either with colour contrast (bold versus duller colours) or tonal contrast (bright versus darker tones). . These filter holders are easily portable, thus a filter pouch is the perfect addition to your kit. We also stock a Formatt-Hitech spares kit for modular holder systems.
