The company decided that software support should be included in our daily tasks in the very near future. Anyways I'm going to make the best of what I can from this training. Photoshop is indeed an interesting software for photo editing and I have always wanted to learn how to use it to do basic stuff.
Here's what I came up with after 1 day of training:
making the blueish photo more natural adjusting the Saturation
changing the color of suby from green to red using layers and color replacement tool
changed the chicken to purple and added a talk bubble
