The Creative Filter System: Graduated
Grads can be vital in enhancing the tones and colours in your photos
Graduated filters have a colour or tone which graduates gently over all or part of the filter and deepens towards the top. Cokin graduated filters come in a variety of colours including Graduated Blue, Graduated Tobacco or Sunset, and can be used to add vivid colour and interest to otherwise bland skies, sunrises and sunsets. Graduated filters are available in subtle or vivid depths of colour and either short or gradual changes in tone from top to bottom.
Cokin Graduated Grey
Cokin's Graduated Grey is a graduated netural density (ND) – and this filter should be in every camera bag. It blocks all parts of the colour spectrum evenly so it doesn't shift the colour balance of the image.
Extremely useful in all outdoors photography, it really comes into its own on overcast days, when there is a big difference in brightness between the flat, white clouds overhead and the landscape itself. Unlike the human eye, your digital sensor cannot record detail in both heavy shadows and bright highlights simultaneously.
Exposing the image for the sky will turn the landscape unacceptably dark, and exposing for the landscape details will make the sky so bright that almost all the tones are lost: "burnt out" to white. In this situation there is often no detail left in the sky to be enhanced in image editing software, and the real potential of the image is lost.
With a Graduated Grey, the top area darkens the sky as the picture is exposed for the landscape, maintaining detail in both landscape and sky – without any distinct colour change. Cokin Graduated Grey filters are available in a variety of strengths and gradations to cater for all situations.
The Cokin Creative System advantage
Screw-in grad filters simply rotate the angle of the graduation but cannot change the vertical positioning. The advantage with the Cokin slot-type filter system is that the filter can be moved up and down in the adapter to accommodate the photograph and its composition.
Cokin P121M Graduated G2 Medium Gray Neutral Density Filter - Often it is necessary or desirable to balance the light intensity in one part of a scene with another. This is especially true in situations where you don't have total light control, as in bright contrasty landscapes. Exposing for the foreground will produce a washed-out, over-exposed sky while exposing for the sky will leave the foreground dark and under-exposed.
Cokin graduated gray ND filters are part clear, part neutral density. They allow the transition to be blended into the scene, often imperceptibly. A ND.6-to-clear, with a two stop differential, will generally compensate the average bright sky-to-foreground situation and is also the most popular density of the series.
Neutral Density Filters Have Four Main Uses
- To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation
- To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
