This picture is the most ambitious photo-layering project I've ever attempted.  The goal was to inject images of figures in different scales interacting with each other  into a great photo.

Here's the progression.

Here I roughly staged the scene.  Note the difference in scale for the various figures.

I took pictures of the figures in each "row". I copied and pasted each individual as a separate layer and resized each to a common scale. Note how the 'tiny' 54mm Marx figure now matches the others.

Three Elastolin guys and two Conte Conversions came next.

Three Conte metal figures.

Almost done.  I didn't like how the converted Conte figure in the middle was blocked out by the Central Norman, so I moved his layer to the right a little.
