The thesis The ratio between painting and photography analyzes two artistic directions, photography and painting. I look closer to the formation or development of photography and its impact to painting. In continue i also write about dvelopement of painting, where we can not avoid the question of how it is the ratio between photography and created painting. I was interested in how painters accepted invention of new medium , and if this infected their work in the past just like in the present, or how the photographers were accepting that older artistic direction. More precisely, i also analyzed the formation of rendering act, which was all from the begining, of both artistic directions, one of the most common depicted themes. For better understanding of ratio between photography and painting i exposed some of more visible representatives of fine arts, who used a photography in their paintings, especially female act. In the last part of thesis, on the basis of theoretical basics, i present an example of use photography of act, as templates for formation of painting with acrylics.
