Use the corners to drag in and out to resize or hover over the corners to bring up the rotation,
you can also flip it if you drag from one side over to the over.
Use the polygonal lasso to select parts of the image you wish to remove. You do this by clicking around an
object, and when you double click it will create “marching ants” to show your selection around the edge.
Go to image adjustments and threshold with the top layer of your collage
selected, this will create a shadow effect ready for your inking.
Use the threshold tool to get the effect you want. You can duplicate layers by
dragging it down to the new layer button, this gives you more freedom to use
the threshold on different areas if some areas look too dark.
Do this for everything in your image until you are happy.
This time use the pen tool on a new layer to go over the black shadows for your inking, this time instead of using
stroke when you right click, go to fill. This will give you your inking effect.
