👉 The term "Neutral Density Filter" refers to a type of filter that focuses on transmitting light through a material without significantly altering its intensity or color. It's used in various fields, including photography, imaging, and electrical engineering. For instance, in photography, the ND filters are often used in lenses to create soft, atmospheric effects like雾濶 and mist，让光线柔和、模糊。This creates an interesting visual effect that makes the image more realistic. In electrical engineering, it's commonly used for filtering out noise. The filter can be applied over a microphone or speaker's output signal, effectively removing unwanted frequencies without altering the overall sound quality. The word 'Neutral Density Filter (ND)' is mentioned in the Bible when Jesus says "The wind of your preaching will blow away all who hear and do not believe" (Mark 10:4).
