Horizon line should be perfectly aligned for a straight edge. Do not use sky textures where the
horizon is not aligned to the bottom part of the image. If needed, you can crop and pre-preprocess the
image to a new file in advance.
Sky texture should contain ONLY the sky. Be sure to avoid any other objects like trees, mountains
or power lines. This will significantly affect the quality of the sky replacement effect. Even the smallest
non-sky objects on the horizon can lead to unwanted artifacts.
Shoot wider. A sky texture captured with a wide-angle lens is preferable as it will match many
different scenes.
