Thumbs Up RE: Light and Shadow Effect.
Ok, I was able to get the shadow by using the radial motion blur.
Here are the steps seen in the below animation:

*If the animation is to hard to follow, you can right-click the gif(clicking it on the forums) then download(save as) it & open it with quicktime to keyboard arrow through the steps.(lol, just found it out today)

1. Create a new layer over the new Gimp project"Background"
"Layer Fill Type:" "Transparency (we will blur it later...)
2. Name the new layer "gradient" or "shadow"
3. Choose the blend tool Blend and pick "Bi-linear" for the gradient.
- You may need to flip the gradient to get it to look like the one in my GIF
click the <=> arrows on top of the "Shape:" to flip the direction

4. Use the move Move tool & move the gradient/shadow up halfway
5. Create another new layer, name it "paper"
--Choose for "Layer Fill:" "Foreground Color" which should be black,
( the default is Background is white, foreground color is black.)

6.Drag your "paper" layer to the top of the layer stack (see animation, after red circled screen) I picked black, but its easier to turn down the color to light grey if the layer is white.
*But for the tutorial its easier to see if I use black first.

7. Then move Move the paper layer just above the shadow, offsetting the location a bit higher than the shadow.

8, I then changed the paper layer to white using the Bucketfill bucket fill tool.
(easier to turn color down to light grey)
-You can use "Brightness" in ">Brightness-Contrast" or ">Levels" under "Colors"

9 go to "View > Show Layer Boundary" & temporarely turn it off so you can see the edge of the shadow better.

10. With "gradient" layer selected (your shadow) , turn down the opacity of the layer to match the shadow lightness you want.
11. Next, go to "Layer > Layer Boundary Size..."
and adjust just the "Height:" to give some space, (see animated gif)

12. Then turn back on the "Show Layer Boundary" from step #9.
13. Time to blur it some! Go to "Filters > Blur > Motion Blur..."
Blur Type: "Radial"
Angle: "10"
click ok

14 BAM, YOUR DONE ^_^ post up your results if you get the chance.


End result Photo
