My favourite art filter on my Panasonic camera (GX8) definitely is Dynamic Monochrome. It's the only art filter I use on the Panasonic. I like the contrasty almost film like look of the pictures it produces. When looking at these pictures they look like they were made in the old days, before the invention of smartphones and digital cameras. This is even more emphasised with the proper subject. Like the picture of the old car at the bottom of this page.
