Shooting in a portrait orientation with a wide angle lens can produce wonderful images, even landscapes (which are more commonly shot using landscape orientation). Going vertical allows you to pack a lot of information into the frame, basically from your feet to way up in the sky.
SHOOT FOR THE SKY
If you have some nice cloud formations, don’t forget to point that lens up at the sky. The wide angle can pull in a huge portion of the sky and make for a great scene.
