Learning key Photoshop tools

With an in depth session on Photoshop with Rob Roach I learned a vast amount of ways to edit photos and make them look much better. In the first part of the session I learnt about layers and how you can stack them to create the desired image. Then I found out all the different ways you can change the look of a photo by using the contrast, saturation, black point etc. Afterwards, I used the quick selection and mask tools to completely change the background on a certain part of an image.
