Don’t.
This one takes a bit of explanation. You might be thinking that the sun is so bright at noon…the colors so vibrant…a perfect time to get a landscape shot. Ironically, no. That sun directly above your head casts no shadows. No shadows…no contrast…no details…flat photos.
The best time for landscape photography is from just before sunrise to just after sunrise and same at sunset. If you are going to be shooting “midday”…try to shoot before 10am or after 3pm…at least the sun will be giving you some shadows to work with on your photos.
