“The Impressionists were the first to reject the absolute value of the subject in the painting. For them, a green apple on a red carpet was no longer the relationship of two objects, but the rapport of 2 tones: green and red.”—Fernand Léger
I apologise for not being so specific about where I find my pictures! It’s a combination of many things.
I live in Australia and last year I completed a visual arts course which I just did for fun. I took one drawing and one painting class a week, and whilst they weren’t focussed on particular periods, I picked up on the work of all sorts of artists.
I went to our National Gallery a couple of months ago and took a notebook with me in which I made sketches and little observations, and since being home I have jumped on the internet and looked at other paintings from the artists that interested me the most They have quite a wonderful abstract expressionism/minimalism/impressionism/contemporary european art collection.
I also own one volume from the Art of the Twentieth Century series called “The Birth of Contemporary Art 1946-1968”. I haven’t finished reading it but it has so many cool pictures and artists I’ve never heard of so it’s always interesting.
As lame as this sounds, Wikipedia is always a good place to start - type in the name of an artist and often you will find links to other artists which then you can go and google and find on art blogs and websites. There’s hours of browsing!
