Threshold - This setting affects the luminosity of different pixels. Gain - This option boosts certain pixel’s brightness within the frame. Highlight - The highlight values are kind of like colour correction values for the blurred image. Invert Blur Map - Does exactly what it says on the tin, this would effectively turn all the black areas to white and all the white areas to black within your blur map. With the focal distance set to 255, you can now see that the farthest object is now in focus: With the focal distance set to 154, you can now see that the middle object is now in focus: With the focal distance set to 0 you can see that the foreground object is clear, and the two background objects in the distance are blurred out: For example, take a look at the blur map below: If your blur map is the same size as your composition then keep this set to Center Map, if your blur map is a different size, you may need to select Stretch Map to Fitīlur Map Focal Distance - This setting is mostly used to adjust the blur distance. Placement - This determines how your blur map will be positioned/handled. If your blur map uses a different colour mode, set this to the relevant one here. If you are using a gradient ramp or effect on a layer to produce a blur map you will either need to precompose your layer or make sure the second drop-down list is set to Effects & Masks.Ĭhannel - Usually this will only need to be set to Luminance because most blur maps act are black and white. Layer - This is where you can specify a layer to act as your blur map. Traditionally, blur maps will be a greyscale image, the whiter parts of the map will have more blur applied to them, and the darker parts of the map will be less blurred. Rotation - The rotation value will rotate the bokeh to your given value.ĭiffraction Fringe - This value adds more opacity to the centre of the bokeh, if you want an outer ring style bokeh then set this to 500 and make sure the roundness value is set to 100%.īlur Map - The blur map is where you specify which parts of your footage are going to be blurred. ![]() ![]() Set it to 100% and whatever shape you select in the iris shape will become a circle.Īspect Ratio - By default the aspect ratio is set to 1, increasing this will produce a wider bokeh blur style, decreasing it will produce a more narrow look. Roundness - This applies a roundness to the iris shape. ![]() The example image below shows what happens when the iris shape is set to triangle… you can see the rough outline of a triangular shape as the image is blurred. Shape - The iris shape determines the general shape of the blur or “bokeh”. These properties are used to mimic the real life camera iris properties. Iris Properties - In real world camera the blur / depth of field is controlled by the iris of the camera itself. Increase this number to increase the blurriness. Alternatively, go to Effect > Blur & Sharpen > Camera Lens Blur The camera lens blur settings:īlur Radius - This is effectively the amount of blur being applied. With your adjustment layer selected, search for “Camera Lens Blur” in the effects and preset panel and double click the effect. If you don’t want a layer to be blurred, simply drag it above the adjustment layer. When applied to an adjustment layer the camera lens blur will affect all the layers underneath it. In the majority of cases the camera lens blur effect should be applied to an adjustment layer in After Effects. To create an adjustment layer go to: Layer > New > Adjustment Layer. How to apply the camera lens blur effect Step 1. ![]()
