Amaryllis, from the genus Hippeastrum of the family Amaryllidaceae, are the glorious lily-like flowers that grow indoors during the long months of winter. They grow so rapidly and the blooms are so huge and colorful that they help us pass the time until we can actually get out into the garden and dig in the dirt. Below, instructions on making a composite of amaryllis blooms in Photoshop.

Setup for photographing amaryllis, setting the plant on the floor, using black poster board as a background with a lamp on top of a dresser for the light source. Take pictures from different angles for this composite.

Unlock, add a new layer, and drag the new layer below the original layer.
Delete the background for the flower layer using your favorite method.

You should have two image layers above a black background.
Go to CTRL+T on the selected top layer to transform it to the size you want. Hold down the Shift key while you transform in order to keep the proportions constant.
