Layers
Todays lesson taught us the importance of using layers in photoshop. Layers are a good tool to use as they create another layer to make adjustments on our image. As layers are nondestructive this allows us to come back to the image and make further adjustments or remove previous adjustments. A layer is exactly as the name suggests it would be the same as putting tracing paper over the original image and making adjustments this allows you to remove, or just make the layer not visible, to go back to the original.
And just to add a bit of relevant info on the benefits of using layers from:

Why work on layers at all?
- They do not destroy your original photo.
- You are working on top of or on copies of that photo.
- You will have more control.
- You can use blending modes to change the way layers interact.
- You can change the opacity of any effects.
- You will have or can add layer masks so that you can work selectively on your photo with any adjustments you make.
