Digital skills - introduction

We have been introduced to a new module, digital skills, this module is about the logged progression of skills through the participation of group tutorials.
Todays first session was about image manipulation and tonality.
Tonality is the overall colour and theme of the piece as you can see bellow the image started off vibrant and colour full but with the use of the level option and the saturation options on a new non destructive layer i am able to reduce the saturation of colour and increase the amount of shadows and highlight to produce a darker and colder picture.
