You can (1)
So, we use one of them and then manipulate it? I'm just wanting to make sure I understand.
copy one of these and manipulate it if you want or you can (2)
go out and find a similar subject and shoot one of your own that you would be happy with. EXAMPLE
(of using these as a subject): Let's say you want to improve on the shot of the road over the hill with the clouds and sky on the horizon, you would just go out and try to find a shot with the atmosphere connected to an earth-bound foreground in some way. Be as liberal as you want in this interpretation
. Some people are masterful at layering images so they may find that this allows them to layer in something that they shot with one of the ones I've put on here.
NOTE: I walked around for a few minutes yesterday with the 50mm so I would be forced to use my feet to compose (or limit my composition) and took three and pulled off the road this morning and shot the two with the blue Chicory in them.
