Application materials and 
Using gray filters you can use slow shutter speeds so you can for example create a cloudy sky or water surface smooth and soft, or people walking by can make out image "disappear". You can influence the shutter in an innovative and creative way. The filters in this H300-02 kit are made of organic glass and provide an optimal transmission of the light for a high image quality. The filters are extremely lightweight and highly resistant to shocks and falls.
