Quick Film Halation Emulation
What is Halation Halation is an effect in film photography where light reflects off the back of the film/film plane and re-exposes the image. In most film it's typically very controlled, and it's a subtle effect you sometimes notice. The below photo has a bit happening on the brightest spots. I honestly never really thought much about it, as while you would see it on very bright objects, it was very tame, and just part of the natural look of film. This is a trend for very bright edges in a film image to bleed into the surrounding area. It tends to be reddish due to how the effect happens. We can make some general observations from this photo. It's reddish in color It's soft and blurry It's only around the brightest highlights It's more pronounced between highlights and much darker parts of the image. With that in mind, it helps to consider what is happening in a simplified cross section of color film. Color film generally works by having 3 light sensitive layer
