For example, here are some of my favorite paintings - Dutch, of course... NGA - Dutch Landscapes and Seascapes of the 1600s.

I like #2 and #5, and have small 11x14 paper copies of them above my desk. You really cannot make out the details of #5 without visiting the museum, as it is so dark that it doesn't reproduce well. Take my word for it, it is fantastic. You can click on the image here and then select 'Full Screen Image' and see a larger version. From there, click on 'Detail Images' to see a series of small sections of the picture, blown up for detail.
