To approach a scene recreation, a tape measurer may help position the subject(s) at the predicted distance(s) from the camera. Students can also utilize the Caliper Tool, using the appropriate Object Caliper on each character in the photo they plan to represent. Note: the caliper will have to match the height of the student posed the same way the character does (e.g. if a student will be posing as Luke Skywalker crouching down looking at a hologram of Princess Leia, that student should have his own crouching height measured and entered into his object caliper).
This is particularly useful for Lessons such as Recreate a Scene.
