As I use Blender for my day job. I have some tips when it comes to emissions.
First of all.. Volumetrics can really improve the lighting. All you need to do is put a principled volume node in, attach it to the volume output and set the density to 0.002. That is the main setting. I would say play with the anisotropy level, too. 0.007 iirc is a sweet spot for most things. it could be 0.7 or 0.07 though. One of them. Don't forget to set the volume light bounces to, at least, 8 in the render properties. (assuming you are using cycles, which, for stills, you really ought to use. Ray trace lighting >rasterized after-all)
As for the emission itself:
This node set up allows you to control how much light the emission material gives off, but it also controls how bright the object is. The top emission node controls how much light is given off from the object (how much it illuminates the surrounding area). The lower emission node controls how bright the object actually is. Which gives you extra layers of control when it comes to lighting.
You can also use this set up with background images too. Say if you have a image as a plane in the background you can use these nodes and simple attach the image to the colour inputs of the emission nodes. You can attach blackbody nodes tot he colour too for a more natural feel colour wise. Also can incorporate IES lighting presets to them, too... If you have them.
My first Blender tips for 2024. Time to go hide, and work, like the ghoul that I am.
