Some years ago, I read a couple of books about photography and composition. Introductory books.
Lately, I caught some interest in drawing. And came across a video that advised to play around with composition, easy drawings, changing where to put 'objects'.
Further I read a post about watching old art works. Since centuries of studies on composition preceded those paintings.

If you would only look at photography, it's probably hard to weed the great from the good or average.

Btw, I am nog claiming I am a good photographer or any sort of artist. I do like understanding things, gathering a better feeling, more knowledge ... ;)
