Haze from a can — that sounds practical. Aerosols, after all, have only been a real concept to me since the pandemic, as these particles are inhaled and can carry nasty viruses. So we're talking about a real, billowing mist that you can always have with you.
But the spray has now been in my cupboard for over a year, as such cans are not allowed to be carried on planes in checked baggage. I had not thought of that when I bought it. But now I finally had the chance to test it in my hometown Frankfurt.
Fogging the background only
I fogged the room a bit and that only took three seconds. The spray does not smell and does not cause cough irritation. According to the manufacturer, it is absolutely harmless, but highly flammable. So don't light candles nearby or anything. An important note, I believe.
When backlit, you can see the haze and it adds a bit of depth to the image. Is this really adding anything to the image. Is it really worth it?
Fifteen minutes later at the latest, I knew the answer when the fire alarm went off. I immediately knew where the penetrating beeping was coming from and I tore open all the windows and waved the mist out.
So I haven't found a real use for haze spray yet. Outside, the wind would carry the fog away too quickly.
