I have a few questions about light and rendering.
1. is there a way to make light rays visible in the air after rendering? So similar to soft fog. I think this effect should be strongest with hard sunlight.
In stage lighting (concerts, theatres, etc) you can also see this well with spotlights in combination with hazers (fog machines for thin fog).
2. Are there also (artificial) light sources that offer a similar hard and focused light as very narrow spots, i.e. only a few degrees of exit angle.
3. are there even more extreme light sources such as laser light?
Thanks again for all your hints and tricks
