Well, Polaroid is purely fictional. The story and characters are made up by the creators for entertainment purposes. There's no connection to any actual true events or people.
Tricolor filter was a filter made up of red, green, and blue colors. It was used in photography, colormeters, and liquid crystal displays. In a color LCD panel, each picture element was usually composed of three liquid crystal cells, and each cell had a red, green, and blue filter in front of it. Different colors could be displayed through the light of different cells. The principle of the tricolor filter was to use the characteristics of the filter to achieve a color effect according to the transmission rate of different colors of light. In photography, the tricolor filter could be used to combine black and white films to create a color image. In addition, the tricolor filter also played a key role in colormeters and liquid crystal displays, which were used to measure and display different colors of light. In general, the tricolor filter was an important optical component used to achieve color effects and color measurement.
The Japanese filter was a filter used to adjust the color tone and effect of a photo. It was inspired by Japanese photography. You can use different methods and tools to adjust the photo to achieve a Japanese style effect. For example, you can use filter mode and increase the brightness of the layer to adjust the color tone and brightness of the photo. In addition, by adjusting the brightness curve and color saturation, you can also achieve a Japanese style effect. In addition, some color matching software such as Vsco and the Exposure7 plug-in also provided a Japanese-style filter option. In short, by using these color matching methods and tools, it was easy to adjust the photo to show the effect of the Japanese filter.
I don't have information on who specifically wrote 'love is a polaroid fanfic'. There are so many fanfic writers out there, and without more context, it's difficult to determine the author.
I'm not sure specifically as it could be various things. It might be a fan - made story related to Polaroid in the context of love. Maybe it tells a romantic story where a Polaroid plays a significant role, like the characters use Polaroid pictures to capture memories of their love.
To make Polaroid pictures work in a story, you could have them as a way for the characters to capture special moments or as a mystery element - like finding someone else's Polaroids that reveal a hidden story. Also, you can describe the physical appearance and texture of the pictures to make them more vivid.
