Photoshop Notes

 First you need a selction (object), copy and paste the layer, or drag using the move tool to move a layer to another layer (background selection). In photoshop, they are eyes on your layers (icons) that shows if the layer can be seen or not. To create a shadow, you need to create a copy of your object, select it, lock the transparency, fill it in black, unlock it, then Gaussian Blur it. To get a selection back, ctrl key and click on the small picture on the layer.
