So one thing I’ve found to be very handy in Photoshop is the free transform tool which can be enabled on a layer by pressing ctrl-t. What this allows is the target layer to be rotated and scaled. This is particularly useful when you are copying something from a different image into another image to make a composite. In this case you’ll see I’ve taken a picture of Martyson and put him onto Fidel Castro’s body. It was good fun.
Its rough in some ways but the important part is that I could quickly get the composite layer (marty’s head) onto the image and fit it by rotating and sizing it, stretching a bit.
