Dino Franco Berguglia Posted September 26, 2019 Share Posted September 26, 2019 Hello, I am trying to understand how this phenomenon can occur, In the movie '' Good Time '' of the Safdie brothers, I have noticed several times that the highlights that flare restore the source, not by a glow but by drawing of it. In the case of the example number 1 we see that the text in the window is present as a flare but that, it does not make a ring / point in flare but a reproduction of lettering neons. In example 2 the flare corresponds to the bulb pattern of the carousel. Can someone explain to me if this effect is due to a phenomenon of the used optics, a lens filter effect, or post-production? I am French mother tongue I hope that I managed to make myself understood. I thank you in advance. Quote Link to comment Share on other sites More sharing options...
Max Field Posted September 27, 2019 Share Posted September 27, 2019 That happens in the optics and not post-production. I used to get it a ton when I'd use LED panels as rim lights. 1 Quote Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted September 27, 2019 Premium Member Share Posted September 27, 2019 It's an inverted ghost reflection between the lens and a filter, or between the lens elements, or between the lens and the sensor (if digital). Sometimes the effect is called narcissus though I'm not sure if that's correct. If you want to see a lot of them, and anamorphic flares to boot, look at the first part of the Playboy Bunny scene in "Apocalypse Now" as the boat passes the lights. 1 Quote Link to comment Share on other sites More sharing options...
Dino Franco Berguglia Posted September 27, 2019 Author Share Posted September 27, 2019 Hi David, thanks for the quick reply, I looked again at the Apocalypse Now scene and the effect is the exact same as in '' Good Time ''. With the only difference that '' Good Time '' was shot in 2 perf with spherical lenses. So according to what you explained to me above, the distance between the filter and the optics could do that, right? A simple '' clear glass filter '' with a little distance could do that? or is it better that I use a '' glimmer glass '' to accentuate the effect in your opinion? what would be the best option to reproduce this in your opinion? once again thank you for your answer.

Premium Member David Mullen ASC Posted September 27, 2019 Premium Member Share Posted September 27, 2019 I think this happened inside the lens, not due to a filter. So test lenses to see which one does it the most. But yes, any glass filter would increase the chance of this effect, doesn’t have to be diffusion. 1 Quote Link to comment Share on other sites More sharing options...

Philip Reinhold Posted September 29, 2019 Share Posted September 29, 2019 If you want to enforce them you can use a Clear-Filter and a Mattebox on Rods where you can adjust the distance of the Filters to the Lens. On some Commercials i used a Clearfilter on a micro-clamp and a nogaarm mounted flexible controllable in front of the Lens to get some Light reflections. 2 Quote Link to comment Share on other sites More sharing options...
