After about 3 hours of looking, I was able to finally get the ID for the boot on the right- Belleville TR393 Flyweight, desert tan, using the proprietary TR Adrenaline outsole.
This is a photo of Anatoly Lebed and Andrey Andiev (another Russian volunteer who fought in Kosovo) in Macedonia during the 2001 conflict as volunteers in the Macedonian special police unit. The third guy is probably another Russian volunteer, though I'm not sure.
Effective_camouflage seems rather useless, camouflage should be generally effective in it's environment by default so the only thing that should be tagged are instances where that's not the case. I could see this being used in instances where a person or object in the photo really really blends in which I assume you're using it for but I wouldn't classify the guy in the back as being that hard to see.
You could also do atmospheric_gradient but that's a little boring.
I think just high altitude would cover that. Holm of the sky is not a term I've ever seen before and Karman Horizon is understandable if you know your terminology but has various interpretations based on context and is not intuitive for tagging.
Might be an infrared_view of the su-35 on the bottom left but I'm unsure, I'm guessing due to the reflective parts mostly being visible while the two-tone camouflage isn't noticeable.
