Photographs mostly show the beautiful, glamorous side of nature. Peaceful feelings, calming green, harmony. I want to show the vile side of nature in a photo series, as it is connected with (dehumanized) human body.
Art nude shots of full body in nature, as nature reclaims the body, torso, torso or body parts in water, mud, dirt on face with eyes open, blood, mould, tendrils, worms and bugs (close-up, placed on human skin), burnt trees, textures of nature with textures of human (close-up, non-figurative nude). Human body tied up or covered by nature. Close-up of decay, rotten plants, mushrooms, flesh. 

Deep natural colours. Maybe Reala Ace with high saturation, or perhaps Velvia, just have to get rid of the purple overtones. Try to introduce some of the aesthetical elements of film Fitzgerraldo and the documentary Burden of Dreams.

Black and white shots like the editorial shots of the movie. Dark shadoes, grainy, gritty... maybe even use film for some shots.

Full nude, no human-made garments. In case model doesn't do art nude, then only show body parts that don't count as "sensual" (legs, feet, head, arms, face, etc...). Composition and poses should not be erotic or sensual. More like just the crude, raw forms and shapes of nature and human body. Take it as a documentary of raw existence.

Full quote: "We are challenging nature itself and it hits back and that's what's grandiose about it, and we have to accept that it is much stronger than we are.
Kinski always says it's full of erotic elements. I don't see it so much erotic. I see it more full of obscenity. It's just - Nature here is vile and base. I wouldn't see anything erotical here. I would see fornication and asphyxiation and choking and fighting for survival and... growing and... just rotting away. Of course, there's a lot of misery. But it is the same misery that is all around us. The trees here are in misery, and the birds are in misery. I don't think they - they sing. They just screech in pain. It's an unfinished country. It's still prehistorical. The only thing that is lacking is - is the dinosaurs here. It's like a curse weighing on an entire landscape. And whoever... goes too deep into this has his share of this curse. So we are cursed with what we are doing here. It's a land that God, if he exists has - has created in anger. It's the only land where - where creation is unfinished yet. Taking a close look at - at what's around us there - there is some sort of a harmony. It is the harmony of... overwhelming and collective murder. And we in comparison to the articulate vileness and baseness and obscenity of all this jungle - Uh, we in comparison to that enormous articulation - we only sound and look like badly pronounced and half-finished sentences out of a stupid suburban... novel... a cheap novel. We have to become humble in front of this overwhelming misery and overwhelming fornication... overwhelming growth and overwhelming lack of order. Even the - the stars up here in the - in the sky look like a mess. There is no harmony in the universe. We have to get acquainted to this idea that there is no real harmony as we have conceived it. But when I say this, I say this all full of admiration for the jungle. It is not that I hate it, I love it. I love it very much. But I love it against my better judgment." (Werner Herzog, Burden of Dreams)
