Drop Shadows


This gives only the basics to adding your own shadow to a layer. Generally, this approach is used when the image is masked (by a non-inverted mask). Since ProShow shadows on a masked layer are themselves masked (hidden) another step is required to give your masked image a shadow. Alternatively, if the ProShow shadow is not what you’re looking for (for example, is too small and/or too sharp), you will need to do something else.

So, to add your own shadow:

  • Duplicate the mask (this retains any keyframes, keyframe settings etc of the original layer).
  • Move the duplicate layer to below the masked image.
  • Change the duplicated layer’s color to the desired shadow color
  • Adjust its opacity (generally 50% to 70%)
  • Add blur (generally 20 to 40 will work)
  • Offset it’s position slightly relative to the mask (change the pan-x and pay-y to place the shadow where you want it and to make its size as large as desired)

So, this is the final basic setup on the slide:

Layer 1: Mask (set to alpha(transparency) or intensity(grayscale) mask, non-inverted, depth=1)
·  Layer 2: Image
Layer 3: Shadow Layer

  1. Important to point out that the mask be a shape sitting on a transparent layer. It doesn’t matter if the actual mask is set to alpha or grayscale, of course.


  2. Yes, Perhaps I should have noted the assumption that the mask shape have a size less than full screen at some point during the slidetime. Only then is the user drop shadow visible. The assumption was that this was obvious. In fact, that is not necessarily the case.

    With respect to the mask type, if object on the layer is an image or is a solid/gradient of other than white-only color, then you’ll probably want to use an alpha mask if you want a shadow of non-varying translucency. Otherwise, a grayscale mask works fine.
