Simple: Create a gray solid, use the pen tool to define the shape of the shadow with a mask path, set the blend mode to multiply, adjust the opacity of the gray layer to control the look of the shadow, animate the gray layer position.
Complex: Separate out foreground, middle ground, and background elements of the shot using multiple copies of the layers and RotoBrush or mask tools, create a shadow layer as described above, then insert it between the appropriate elements.
A screen grab of your scene would help a bunch. This effect could take 2 minutes or 40 hours depending on the complexity of the shot.
First technique should work, but you could make it more effective if you cut out the photographer and used two copies of the shadow to pass over him.
Do you know how to animate position? Are you a new user?
I am very new to this...so I do not know how to animate position.
I'm sure I can look it up and not take up more of your time.
Thanks for the answers though they are super helpful!
Here's what a project would look like. I've included the mask cutting out the photographer. You can see the opacity and the position keyframes as well as the blend modes. The solid is dark gray. As the shadow approaches you'd bring in another copy over the top layer of this comp with the position slightly offset to help sell the effect. It's not necessary to roto out the actor, but it helps sell the effect.
Please take a look at the Getting Started section of Todds blog. Lots of good stuff there.
Thank you so much!
