In her ongoing series called Morphologies, Lehto is fascinated by colour combinations and living things: human bodies and plants. Their different and changing forms are something she explores.
Lehto is keen to stage photos and build props by using flowers and different materials. The project started in 2015. During the summers Lehto took long walks in nature gathering flowers that interested her for their form and colour. It did not matter if the flower was already dead or just beginning to grow. Some of them she used right away in portraits and in still life arrangements, and some she let dry for over a year and used them after that.
Both beauty and rejection of it are something that she is interested in.
