The Cokin Filter A061 Center Spot Incolor 2 allows you to emphasize the centre of an image while blurring the surrounding area. This filter is available in two gradations, A060 Incolor 1 and A061 Incolor 2, with the 061 filter having a greater effect than the 060 filter. You can use this filter in combination with e.g. colour filters to obtain an even more dramatic effect.
The filter is directly influenced by the set aperture and the focal length. If you use a larger aperture, the filter will have a softer effect on the photo. The size of the circular area that is rendered sharp becomes larger when using a longer focal length. Exposure metering must be done without the filter attached to the lens. If your camera has spot metering, you do not need to remove the filter from the lens to determine exposure.
