Advice on how to replicate these little flares floating around her head in Three Colors: Blue
Hi there, just to preface, I'm a director starting some very early planning on my next short I hope to shoot in January. I recently watched Three Colors: Blue for the first time (loved it) and this moment really struck out to me. My DP and I were planning to use light near the end in specific ways to evoke a specific feeling, though that would be more of an editing trick by using artificial film burns we would shoot in a dark room through a glass and then double expose over the footage shot. My thought after watching the film though was we could do something like this as a tease used earlier in the film by having lightly dancing flares like these appear during specific moments in the short.
My question is, for anyone that has scene the film, how did they make these suddenly appear without cutting away or adding any noticeable lighting change into the frame? Is it perhaps it's own double exposure or am I just being dumb and it's as simple as shining a small light that didn't change the lighting of the scene much into the lens from like above or below? My apologies if it's obvious, I'm just not finding it with a few different searches. Or if anyone doesn't quite know exactly how they did this, I would be happy to hear alternative solutions for a similar lighting effect.

I couldn't simply find the scene as it plays in the film with music and whatnot online, but did find it in this analysis video. If the timestamp link doesn't work, the shot starts at 1:41.
Would gladly appreciate any help or insight!
