I wrote an article on inward lighting on the current UWP issue https://www.uwpmag.com/?download=129
Due to technical reasons Peter had to truncate the post processing section, if you are interested the complete article is here https://interceptor121.com/2022/10/30/a-deep-dive-into-inward-lighting/
I have seen a few posts that talk about low visibility and backscatter this technique minimised but of course does not eliminate backscatter and may be worth trying
For less extreme effect you can pull the strobes backward and point more forward as shown in Alex Mustard Underwater photography Masterclass book
