Here are some screenshots which show techniques I’ve covered with Photoshop.
This screenshot shows inner glow within layer styles. The structure changes the images colour and shade, and It can make the image darker or lighter, that is used with the opacity slider. The two images below show this. The one to the left is the original and the one to the right is the edited.
These screenshots show multiple things. The image to the left shows a colour balance adjustment layer. Colour balance changes how much of a certain colour is in an image. For example you can make the red stronger and the yellow weaker. The two screenshots below show this. The left is original and the right is edited.
The screenshot to the top right shows how to rename a layer. This is a simple technique. All you have to do is double click on the text.
The screenshot to the bottom right is changing layers around. This is also a simple process. Click on a certain layer and drag it up or down, depending where you want it. A thick white line should appear between layers, that is where the layer will be placed.
This screenshot shows typography which I’ve created.
