We hear a lot at the moment about the benefit of spending time in nature, of embracing the fresh air, getting outside and away from technology for a while, of getting some exercise. There are even cartoons about people enjoying images of nature and posting them to share with their friends from the comfort of their computer desk or couch. Virtual enjoyment of nature if you like.
There's also a lot we can gain from noticing things in the outdoors. We can see the colour, noticing that there probably are fifty shades of green. We can notice people. People walking, cycling, sitting, running, etc. We might say hello or nod to these people as we share the space.
We can notice images that we might take a photograph of to keep for later. If we look with a photographer's eye, looking for sights that will be worthy of keeping, we will notice more.
We will look for colours or images that touch us in some way. We will notice symmetry, reflections, juxtapositions, even ironies. Our mind will be stimulated in ways not possible by looking at a computer screen.
