This is the tool Fleischer studios used back in the 1930s when they needed a sense of depth in their cartoons.
Like it or not but having only cels on top of a background is not gonna be enough. They're just flat drawings layered over a background art piece but what if you have foreground objects on front of your BG, either behind or in front of your characters? Well the use of cel layers just aren't gonna cut it. I mean it could but you'll need a way to capture depth as well since things in real-life move in parallax from one depth field to another. And that's where the Fleischer camera comes into play.
Before Ub Iwerks sold his multiplane camera patent to studios, other people were experimenting with adding depth to their cartoons. Fleischer was no exception. They made a system that let them layer more cels to create the believable feel of depth.
Not only that but it also let them use 3d models in their animations as well.
When I say 3d models, I don't mean cg since computers in the 1930s were still vacuum tubed based and only available to mathematicians and scientists.
The 3D models were actually literal models made from plastic, clay, etc. Think of them as miniatures.
The use of 3D models meant that you have all the perspective you need, something that the multiplane camera unfortunately doesn't have since the drawings are still flat.
Unfortunately, the setback camera wasn't sold to others. Either because Fleischer didn't want to sell the patent or it's the way the setback camera was setup to begin with.
You may notice that the setback camera is constructed horizontally.
Well, many artist at the time weren't willing to invest a lot of money on a camera setup that requires the artwork to be layered horizontally.
Instead, they invested in Ub Iwerks' multiplane camera setup.
My guess the industry preferred Iwerks' Camera system because it allowed them to have a sense of depth while at the same time, allowed the artwork to be photographed downward just as we intended.
By the 1980's this system was seldom used due to costs. An animator as well several artist attempt to do computer animation with 2D Characters.
While this was a technological achievement, the higher ups didn't think so.
Now we have the computing power to combine CG Backgrounds in our animations using tools such as TOON BOOM HARMONY.
For those curious about what cartoons did Fleischer studios use the setback camera, here's a link to the a Vimeo Video that shows all the examples of what cartoons used the setback camera:
Update as of February 3 2024:
I've since upgraded my own computer space. When I did these earlier blogposts in the beginning of 2023, I was still using my MSI Laptop but I now use my custom built PC for all my posts.
