Each of these shots is about 80% photograph and 20% Photoshop. Even with the Canon, the magic doesn't happen until it's been through the process to make it "pop." And of course, that process also works for images captured by the Lumix superzoom "bridge" camera that's been my workhorse for a long time now...
...it's just waaay harder trying to squeeze the quality out of the overall-soft images from a 1200mm zoom lens. Half of the Canon magic is that the landscapes are captured with an 18-45mm lens, and they're consequently that much crisper. Add Photoshop jiggery-pokery, and here we are!
