The high point in modern art

Drag the white button on the image to compare the romantic painting representing the abstract aspects of nature with the abstract expressive work that directly reflects the expression of colors with personal meaning.
Move the mouse over the surface to observe how an objective photo (left) evolves in the process of abstraction to an abstracted work in the middle and finally to a non-objective painting (right).
First there is a realistic photo of a tree.
In steps 1, 2 and 3, the spectrum of abstracted paintings of trees can be seen.
The image of step 4 is an abstracted painting in which the tree is so reduced that it is no longer recognizable. After step 5, the paintings are in the realm of non-objective art. Finally, in Step 6, Mondrian no longer needs to trace the tree, instead he starts painting with purely visual elements.
So his paintings are no longer abstracted, but pure abstract. For this reason, the works bear abstract names after the visual elements, like Piet Mondrian's "Composition with Red, Blue and Yellow" from 1930.

purely abstract
like this „Action painting“
by „Franz Kline“
This style lacks a clear focal point
like this „Color Field painting“
by „Mark Rothko“
New York school paintings do not have a clear focal point because most of the artists held strong convictions based on Marxist ideas of social and economic equality.
Works of the New York school are in large scale
like this „Action painting“
by „Jackson Pollock“
Abstract expressionism is characterized as
non-objective
like this „Color Field painting“
by „Barnett Newman“
There is no unified artistic practice
