“Kenko Rainbow Halo” is a prism filter that refracts light through a conical glass element to impart various effects on your work. Its effects vary significantly based on the focal length and aperture of your lens, as well as how you incorporate light sources into your composition. With creative ideas, it can unlock new forms of expression. It's a recommended effect filter for creative photography and video production.
The “Rainbow Halo” primarily offers two effects: Spiral-like Bokeh Effect and Light Ring Effect. Achieving these effects becomes easier when specific conditions are met.Capture your own unique and original works.

【Rainbow Halo Effects】
■Effect ①: Spiral-like Bokeh Effect at the PeripheryCreates swirling bokeh that envelops subjects at the edges of the frame, making the central subject stand out.
Utilize this bokeh effect for portraits where the main subject is clear, or when unwanted elements appear in the periphery, to emphasize your subject.The shorter the lens focal length, the wider the bokeh area; conversely, a longer focal length narrows the bokeh area.

■Effect 2: Creative Effects with Light Rings (Rainbow Rings) and Ghosting by adjusting how light is captured.
The Rainbow Halo can also produce rainbow-colored light rings or ghosting effects.The conditions for creating a ring within the composition are: shooting outdoors on a bright, sunny day with a point light source placed at the center of the frame. Furthermore, if the light source is a strong light like an LED light, the ring becomes rainbow-colored, creating a beautiful rainbow halo. A smaller light source tends to produce a thinner, more beautiful rainbow-colored ring.Additionally, when used during video or film shooting, you can enjoy bokeh and rings that change moment by moment depending on the situation and time.

It's also recommended to fix the camera at a fixed point and enjoy the changing patterns.

*Key Points for Rainbow Halo Photography
・The range of bokeh changes with focal length, so using a zoom lens allows you to adjust the bokeh range while shooting.
・When shooting against the light, excessive ghosting or reduced contrast may occur.
・Depending on the lens, autofocus may not function correctly. In such cases, please use manual focus.
