Q: You can add a drop shadow to any layer in Photoshop Elements, from singular objects in a picture to text and graphics. Open up a copy of the image you need to add the shadow to.  If you want to make a drop shadow on text, you'll need to write it out and turn it into a layer by right-clicking on it in the layers menu (on the right) and clicking "Rasterize Type."  If you just want to learn how to make drop shadows, use the text as described above on a white background -- it makes it much easier to learn. Selections are when you outline an object with the moving dotted line. You can use the quick selection tool, the lasso, or the square selection tool to trace out your exact selection. For simple objects or text, you can Ctrl-Click or Cmd-Click on the layer's picture in the palette to automatically create a selection.  Don't worry about getting the selection exactly right-- you just need a rough enough outline for a shadow. If your selection is on a one-color background, you can use the magic wand to select the background. Then press Ctrl/Cmmd+Shift+i to get the inverse of your background -- the image. You can Alt-click with your selection tool (magic wand, quick selection, etc.) to subtract a spot from your current selection. You can press Shift-click or Cmd-click to add a spot to a selection.
