16 is the magic number

To capture a landscape photo like this, 

There are a few key steps to follow:

1. Lens Choice: While zoom lenses can work for landscape photography, a wide-angle lens is generally recommended to capture more of the scene. In the example above, I used the Tamron 28-300mm at its widest setting, 28mm. The smaller the focal length, the wider the view.
2. Camera Settings: Switch your camera mode to either Manual or Aperture Priority. This gives you more control over your settings. Set your aperture to f/16 or higher. f/16 is ideal for achieving sharpness from the foreground all the way to the horizon. Aperture values between f/16 and f/21 will help with this task, while still allowing you to keep your ISO as low as possible to minimize noise.
3. Post-Processing: After shooting, use editing software like Lightroom to slightly enhance the saturation and contrast. This will bring out the colors and give the photo more depth.
