Product description

The only function of the attenuator (medium gray density mirror) is to attenuate the amount of light entering the camera, and it will not attenuate a certain color light much and other colors less. Its purpose is to attenuate all light, only the exposure of the film is changed, and it will not have any effect on the relative brightness value of the scene. We can use medium gray density mirrors to change the brightness of the light to adjust the exposure of the film to varying degrees. The effect is equivalent to shrinking the 1st, 2nd, 3rd and even more apertures. Of course, this is not to say that adjusting the aperture of the camera can replace the attenuator. For example, in extreme environments, when the light is very strong, the attenuator has more flexibility to adjust the aperture and exposure time.
