Best Filter to Simulate Film Halation (Highlight Blooming)

The level of halation with film is lighter than the lightest filter, but you may be happy with just using something like a 1/8 Schneider Black Frost, it's probably the lightest diffusion filter I've used. Also there is the 1/2 Tiffen Black Diffusion-FX, which hardly halates at all, but that may be too subtle. Also, the 1/2 Tiffen Soft-FX is fairly subtle.
Otherwise, I think you're better off finding some older lenses that have a bit more flare to them, which I think is actually more the reason you have halation in your 16mm footage, it's the lens more than the film stock.

How about the 1/8 Promist and/or 1/8 Black Promist?
They definitely create the blooming/halation effect, and at the 1/8 strength, they are pretty subtle on the diffusion results.
Have you used them?

Hi. I would use a 1/8 classic white promist for this.
I'm not sure if a black promist would achieve the same halation effect as the classic white promists. In my experience I have found the classic whites to be much stronger.
The medium matters, as does the source and exposure, so starting at the lightest intensity is probably smart.
Here's some 35mm stills showing the effect. I'm not sure how it would look with digital, but anything over 1/2 is too much in my opinion.
And here's some cross processed reversal with a simple cheap net behind the lens.
Hope that helps.
