This 84mm Solid Graduated Neutral Density 7 Filter Kit with Adapter Rings is a cost-effective way to get started in advanced filtration with neutral density filters. It features four solid neutral density filters and three graduated neutral density filters along with a three-slot filter holder, a wide-angle filter adapter, nine adapter rings from 49 to 82mm, and two six-slot filter cases. These filters measure 84mm wide and slide into the holder. The holder allows for up to three to be stacked for a combined effect. There are 1, 2, 3, and 4-stop versions of the solid filters and 1, 2, and 3-stop versions of the graduated filters. Neutral density filters darken the image, allowing you to take photos at wider apertures or longer shutter speeds than previously possible for more creative control. The graduated versions transition from dark at one edge to clear at the other. This lets you choose where you want to reduce the exposure, like darkening a sky and leaving the dark foreground untouched. Additionally, neutral density filters do not affect the color of your image. Control light and colour directly on your raw images at the time of shooting; Keep the quality of your images without excessive post production work; Create specific effects saving time on your computer. Same filter for all your lenses by just replacing the adaptor ring. Otate, slide, decentre in all directions for more precision and creativity.
