Tips for shooting skies:
- There is no Photoshop substitute for a dramatic sky.
- The best skies appear after the sun has set, sometimes quite a while after.
- You usually need to underexpose the shot by 1.5 to 3 stops to keep the detail from washing out.
- You can then tweak the image to bring up the shadows with Photoshop. (Blocked up highlights can’t be fixed.)
- You need an anchor on the ground for your composition. Just a sky doesn’t look right, but if the anchor is silhouetted, you can make it small as I did here.
