Cokin Cokin Centre Spot Violet Filter M (P) – P064 Special Effect Filters

Create A Blur With The Cokin Violet Center Spot Filter

The Cokin Violet Center Spot Filter Has A Clear Centre And Diffused Violet Edges, Which Create A Blur Effect While Leaving The Centre Sharp. The Amount Of Blur Produced Is Influenced By The F-Stop And The Focal Length Of The Lens Used. For Example, A Lens Shot At F/1.4 Will Produce A Greater Blurring Effect Than F/8.0, And An 85Mm Lens Will Create More Blur Than A 28Mm. Additionally, A Longer Focal Length Lens Will Visually Increase The Size Of The Centre Spot Area, As It Sees Less Of The Filter Area.

How To Use Center Spot

• The Shorter The Focal Length, The More Visible The Zone. As For The Transition From Sharp To Soft, It Depends On The Aperture: The Wider It Is, The More Diffuse The Transition Will Be. For A Correct Adjustment With Auto-Focus Reflex Cameras, The Choice Of An Af Central Collimator Is Obviously Required. We Also Recommend Working With Apertures Of F/5.6 Or F/8 In Order To Keep A Sufficiently Blurry Transitional Zone. A Strong Backlight Brightens The Effect Of The Filter.
• Uncoloured Center Spot Filters Create Blur Around The Central Subject In A Completely Natural-Looking Way, Giving The Subject Prominence In The Image.
• Grey And Coloured Center Spot Filters Work By Blurring And Darkening The Periphery Of The Image In A More Or Less Noticeable Way. The Intensity And The Quality Of The Central Subject’S Lighting Are Clearly Emphasized.
• Oval Center Spot Filters Are Made For Larger Or Taller Subjects.
