Not applicable for the disk or completely round filters. Star - A concave shape with the defined amount of points and the specified indentation amount. The three options are:īlades - A convex shape with the defined amount of sides.ĭisk - A circular shape that provides a simple round filter.
This will cause bright areas to become brighter and the lens shapes will become more distinct.Īllows you to select a shape of the filter. When the threshold option is checked, the Brightness Multiplier will be used as a multiplier to the areas of the image that are above the luminance threshold. Areas above this luminance value will be brightened based on the value specified in the brightness multiplier - areas below this luminance value will remain unaffected. When the threshold option is checked, the Luminance Threshold provides a cutoff value that defines the region of the image that will be brightened with the brightness multiplier. When checked, you may set the values for Luminance Threshold and Brightness Multiplier. A higher value will emphasize and sharpen the edge of the lens shape, creating the appearance of an outline on the bokeh highlights. The value that specifies the sharpness at the edge of the lens shape. However, the image will appear more blurred overall.
A higher radius value will make the lens shapes appear larger. The value specifying the size of the filter used to blur the image. Each node must have a name that is unique to its containing group. The name of the node as it appears in the Node View and the Timeline view. In Harmony, you can control the shape of the filter used to blur the image in order to create the desired aesthetic for out-of-focus images. The following image is an example of a network for the Bokeh-Blur effect. In Harmony, the Bokeh effect is used to mimic this photographic-appearance by blurring an image with a specified lens shape and amplifying the effect in brighter areas. The filter doesn't filt the lens, a better way to do this could be fitting the filter to the lens hood, but not the filter mount.In photography, Bokeh is the effect produced by a lens that causes the brighter regions of out-of-focus areas to blur in the shape of the lens' aperture. As a result the scope is of the imape is limited to the size of the shaped aperture.Ģ. The shaped aperture on the filter is too small, mush smaller then the size of the light sensitive components of the camera. After consulting some expert in photography, the reason that cause this failure can be conluded as followed:ġ.
The camera used is a Canon 600D, with a 18-200mm sigma lens. On the first trial, The diamater of the filter is 67mm, and the shape diameter is 10mm.
BOKEH FILTER SERIES
Also, I wanna make the a series of filter with different shape.
BOKEH FILTER TRIAL
I have just build the first trial product, and i hope i can refine and perfect it with further adjustment made on the filter frame. Since 3D printer can easily print small shape as the aperture, we can print filter for much complex shape, and we can use lens with smaller aperture(of course it is much cheaper). Taking the advantage of the 3D printing technology, we can print the custom shape aperture as a durable filter, which can be installed on the DSLR lens or even on typical digital camera. In the old days, if we wanna make a nice picture of bokeh with custom shape, we can only use paper or cardboard to make a custom shape aperture.
