What is included in the kit?
The kit includes three hard-edged gradual neutral density filters: a Gradual ND2 (1-stop) filter (P121L), a Gradual ND4 (2-stop) filter (P121M), and a Gradual ND8 (3-stop) filter (P121).
Does the kit include a filter holder or adapter rings?
No, the filter holder and the adapter rings required to attach the holder to your lens are not included. You must purchase a compatible Cokin P Series holder and rings separately.
What is a hard-edged transition filter best for?
A hard-edged transition is ideal for scenes with a distinct, straight horizon line, such as seascapes, flat landscapes, or cityscapes against a sky. The defined transition line can be aligned precisely with the horizon.
Do these filters affect colour balance?
No, these are neutral density filters. They are designed to reduce the amount of light evenly across the visible spectrum without introducing a colour cast, so your image's colour balance remains natural.
What lens thread size do I need for the adapter ring?
The adapter ring thread size is not specified for this kit. You must purchase a Cokin P Series adapter ring that matches the filter thread diameter of your specific camera lens.
Can I use these filters with any camera?
Yes, they can be used with any camera (DSLR, mirrorless, or even some compact cameras) provided you have the correct Cokin P Series filter holder and an adapter ring that fits your lens.
How do I choose which filter density to use?
Measure the exposure difference in stops between the bright area (e.g., the sky) and the darker foreground using your camera's spot meter. A 1-stop difference requires the ND2, a 2-stop difference the ND4, and a 3-stop difference the ND8 filter.
