Okay, so @halsin was gracious enough to send me this lil tutorial in my DMs and I thought it might be useful for others, too so I asked her 8f it was OK to screenshot and put here.
This is just a random portrait that happened because I spawned in a location using AMM and got attacked by her instantly. But I saw how cool she looked and pressed N to take her portrait before she could harm my girl Macha, who was standing there in her stunning bodysuit all defenseless.
I have since learned about passive mode in AMM thanks to @dustymagpie - it makes all NPCs non-hostile so that you can snap pictures without being attacked 😅 its in the Tools section of AMM and you just have to turn it on.
This girl is beautiful, and I was elated to finally photograph Mantis Blades. They look so awesome!
