FX Fractal filters usually have a rotatable design that allows you to adjust the intensity and direction of the fractal effect. By rotating the filter, you can select a different fractal pattern or adjust the density of the fractal to get the best results for your creative needs. This flexibility makes the Effects Fractal Filter ideal for photographers and videographers looking to achieve creative foreground bokeh!
