I saw prints made by Clyde Butcher at a local museum. My first reaction was "WOW!" Then I stood there for a while. I had this feeling of image surrounding me. Later, I read (on his web page), he envisions viewer walking into his image that he purposely leaves a space on his print where the view can walk into. I'm not even a landscape photographer. I'm more of a portrait guy.
Looking at his images on my LCD panel doesn't even come close to seeing his prints, especially big ones.
On other occasions, I saw a print that was rather small, 11x14 maybe that I stood and contemplated for a while. I really didn't know what it was supposed to tell me, but I stood there nevertheless. I never did that with online images.
Rather than asking for others' opinions, I encourage you to visit local museums and see for yourself. It's not a matter of what you *should* be seeing. It's the matter of images just grabbing you. If you can get this from online images, great, but I doubt you do.
