Fourteen, dimming night mirror: ????????Department of gray mirror class. By a strong role in blocking light. In the exposure of the appropriate choice under the premise of the sun can be taken to an excellent night effect. Fifteen, red reinforced mirror: ????????The mirror is a high-grade filter, made by the import of expensive rare earth elements made of imported optical materials. It can make the spectrum between 570-600nm turbid yellow and orange light completely absorbed, while the red light through. So it can significantly improve the red, light red, reddish red objects in the color saturation, make it more vivid, bright, strong. For example, the autumn maple leaves more red, strawberries and tomatoes are more seductive sunset atmosphere is more rich; wedding or Christmas more festive ... ....

Sixteen, gradient mirror: ????????The gradient mirror is one of the most important filters in photography art creation. It can be divided into gradient and gradual diffuse mirrors. It can be divided into soft gradients and hard gradients from the gradient form. The "soft" That is, the transition range is small, are based on creative features selected.
en, leon 81: ????????Leighton 81 Department of warm dimming balance filter, sub-A, B, C, the color of the pale amber can be slightly adjusted to the picture of the blue side of the tendency to restore the true color. In actual use, to Lei Deng 81C as much. 11, Leiden 82: ????????The mirror is a color balance filter. Light blue, sub-A, B, C, this type of filter is characterized by a small change in color temperature for the light source temperature and film balance color temperature roughly the same under the premise of fine adjustment. Twelve, Leiden 85: ????????85 series points A, B, C, is a color temperature conversion filter. 85B can reduce the color temperature from 5500K to 3200K. The mirror is amber, suitable for use in sunlight under the light type film.
Seven, blue mirror (B): ????????For black and white photography. The mirror through the green, blue, purple, red, orange, yellow and other colors.
