Filter set for phone camera lenses: this 77 mm filter set contains 4 graduated colour filters (red, orange, yellow and blue), a CPL filter, an ND32 filter, a 6-point star filter and a phone lens clip, which even fits most mobile phones and multiple cameras and a 37-77 mm adapter ring that fits all DLSR cameras with 37 mm and 77 mm lenses. VVVV | Circular polarising filter: with the circular CPL filters, you can remove unwanted reflections from surfaces such as water, glass, etc. This effect is commonly used to increase the contrast and saturation of blue sky and white clouds | Neutral density filter: The ND32 filter reduces the light entering the camera sensor by 5 levels without changing the colour. You can use a longer shutter speed for creative photos or a larger aperture for a shutter depth of field | Star filter: easily transform point light sources into stars. Use the 6 point star filter to add 6 light rays to your image that radiate outwards from a strong point light source. Perfect for recording street lights, car headlights, reflections on water surfaces, candlelight and other highlights | Graduated colour filters: The four colour filters are made of resin and are double threaded so you can stack filters, which means you can add a colour to one part of the image without changing the colour of the other part. They can help change the mood of your photos - ideal for landscape photography and photography of sunrises and sunsets
