Optical paths

Optical Path: The entire physical route that light travels from your light source, through the film or document, through the elements of your camera lens, and onto the digital sensor. In a digitization setup, every component along this path—from the quality of your backlight to the cleanliness of your lens filters—directly impacts the final image. Keeping the optical path perfectly clean, unobstructed, and free of flare is essential for capturing crisp detail and accurate color.
