Kenko NOSTALTONE series are a filter that was created with the goal of creating a landscape that is "like a scene from an anime", a familiar scene that will move your heart with its warmth.It adds a warm and nostalgic atmosphere, which is enhanced with dramatic flares and ghosting to express the world in a nostalgic way. Two types, NOSTALTONE ORANGE and NOSTALTONE BLUE, with different nuances of color, contrast, and light diffusion effects, are available.【Main Features】■For nostalgic gradation expressionThe NOSTALTONE BLUE has the effect of brightening the shadows while at the same time reducing the highlights, creating a nostalgic image through soft tones. The optical design also allows for the use of a very subtle blue tint. The blue tones in the brightened shadows create an atmosphere that is similar looking to a scene in an anime.■Diffusion effect to feel like being surrounded by gentle lightNOSTALTONE BLUE also has the effect of diffusing light. It diffuses the low morning and evening sunlight, creating a nostalgic atmosphere as if surrounded by gentle light. Since the diffusion effect is strong with direct backlighting, to achieve a good diffusion effect it is best to use diagonal backlighting or sidelighting, or to hide the entire sun or a part of it behind buildings, trees, people, etc. When shooting after sunset, the filter creates an impressive scene through softly diffusing light sources like streetlights, traffic lights, cars, etc.■Dramatic flares and ghostsNOSTALTONE filters create rings of light and ghosts when the sun's rays are low in the picture angle in the morning or evening, creating a dramatic effect like a scene in an animated film.■Comparison ORANGE and BLUEComparing ORANGE and blue, ORANGE has strong coloring, but the softening effect is only slightly weaker. BLUE has a subdued color but a comparatively strong soft effect.Please note that:*In order to produce the filter effect, a coating is applied to the glass to make it more reflective. The appearance of colorful rings of light and ghosting is an intended effect of this filter.**To produce a ring of light, place the sun in the center of the image. The ring is smaller at wide-angle and larger at telephoto.【About Kenko】Kenko is a Japanese brand of photographic and imaging supplies and optical products with a history of over 65 years.
