Ha this takes me back for my Master’s I used an AA spectrophotometer to measure Ca++ K+ and Na+ in water samples… I remember looking in the viewing window at some of the wonderful colors in the flame…and praying that the acetylene and oxygen system never misbehaved and blew me up 
Love this old school video… basically shows the basis of the instrument except it had a nebulizer and you injected a fine spray not powder in a flame…
No need to justify things unless you are clearly trying to make a point I think anyway. Art and vision belong to the creator… I have absolutely no credentials to ever make any critical judgements and so if my words do ever stray into that zone…its because I misspoke via my message…

This is a lovely image - “HDR-inspired” - and a tribute to Magritte.
Notwithstanding the alluring orange lighting, I took the B&W route, as is my habit…
Here’s my ART 1.16.3 sidecar:
