More often that we might like, we end up at a location where the opportunities for photographs are quite good, but the weather is not. An overcast sky that is uniformly grey can be a big damper in creating beautiful scenics, so what do you do?
One possibility, of course, is the shoot the scene and add a sky later in post production. Although this can be successful in some situations, you have to be careful that the sky you add looks believable.
The other option is to look for photographs that do not include the sky, thus eliminating the lackluster quality it brings to the image making process. This is a great time to hone your observation skills, and zoom in on details. Start looking for parts of the landscape that are interesting, things like streams, rock formations, flowers. All can be great subjects in the soft light the overcast sky provides.
