To answer what is “Pretty – Ugly” is really hard. I think it is a subjective thing. The main idea is to find “pretty” and photograph/ show it in “ugly” way or visa verse.
One of the ideas I came up with was to capture the wintry nature and make a beautiful picture of it. In winter plants are dead more or less, it is dry and fade, no colour, no liveliness. The feather I found stuck in it just strengthens the idea.
