When you are shooting photo or video, it is always good to make sure that your camera settings (iso, aperture, depth of field) are adjusted accordingly for environment, subject and light.
However, having these things optimally set does not mean it will render the photo or video the way you want.
Having a powerful post-production, such as Adobe Studio, setup to help give you the look and feel you want and also expedite the work load in the process.
It helps shape the story of the photo and video through color pallet changes, time and visual edits and the ability to integrate computer generated images into the fold.
So not only is editing and retouching a technical aspect of photography and videography, it is also a key component in shaping a narrative in both respective art forms.
