This is called Tilt-Shift it can be achieved with photoshop etc or also ingame but you need an additional program to achieve it.

Requirement:
A. download 'Reshade' – the reason why it is for pc only.
B. Once you install Reshade make sure "CinematicDOF" by OtisFx is also included at shader selection

  1. Once you have chosen the photo you want to take go into photo mode
  2. Open Reshade (Instructions of using it is also on their site. Pls read notes first before downloading it and try this)
  3. Activate CinematicDOF (the reason this style works)
  4. My settings are shown in picture #20
    a. Focusing:
    -Manual is recommended but for beginners auto-focus is fine, adjust auto-focus point to where you want to point the focus
    -Focal length atleast keep it between 200-300
    -Aperture atleast 1 – 2.5
    b. Blur tweaking
    -Far Plane max blur and near max blur – make sure they are almost similarly blurred so it wont look weir on your photo
    C. Others are just optional, you can combine other shaders too like me I included "clarity" for extra punch.

Hope you understand my instructions.
Thank you.
