If there is nothing up there put something down here
The only thing you cannot control about landscape photography is the weather, because as you know we shoot very early in the morning or very late in the afternoon and you cannot be certain that the weather a.k.a colors, clouds, sunrise, sunset, can be very good when you get to a location.
But wherever you are, just make good of what is in front of you. Maybe compose better? If there is nothing up there put something down here…if the sky sucks put some foreground. Foreground can be something with textures, shapes, lines, reflections etc etc.
Hope you enjoy your day!
