Do you know the functions of UV Longpass Filters products
UV Longpass Filters products are glass filters that fit in front of the camera lens and block UV rays. They were once necessary for film photography, but are now used by most photographers to protect their lenses.
UV Longpass Filters products block UV rays as they enter the lens. Think of it like sunscreen for your camera. Some old photographic films are very sensitive to UV rays, so if you don't use UV Longpass Filters products, your photos will end up with a blue haze. This is especially common if you're shooting somewhere with a lot of UV rays, like on a sunny day or at high altitudes.
The problem is, modern film and digital sensors are not sensitive to UV light. It doesn't affect them like it does with older movies. This means you don't need UV Longpass Filters products to block UV rays to take good photos. However, that didn't stop the UV filter from being used a second time as a protective filter for the lens.
