I'm a portrait photographer so I may know nowt...
But if I point my camera at my Mrs first thing in the morning, wearing an old dressing gown and last nights makeup, she'll look crap, so the photo's will look crap.
When I shoot rally cars, I could stay in the spectator area, and the foreground will be a load of anoraks, the background will be a load of signs and safety tape.
The simple truth is, we can only photograph what's in front of the camera. So I wait till my Mrs is feeling and looking great and in the mood for her photo taken, I walk miles into Rally stages looking for a pleasing scene and light direction to surround my rally cars. When we shoot stuff in a studio, it's not plonked against a background, we carefully consider the lighting pattern and work to produce that.
If you want to shoot landscapes with dramatic skies, watch the weather forecast, plan your trip and hope your luck holds, then photograph the dramatic skies.
My favourite explanation when posing and lighting people is 'the magic doesn't happen inside the box', you can manipulate what you've captured to a degree, but you have to capture something worth the work first.
