Atlas Lens Co. came up with its own term for when you need to deliver multiple formats from a single shot when shooting with its Orion or Mercury anamorphic lenses. AtlasScope, as they are calling it, allows you to deliver 1:1, 9×16, and even 16×9, which is handy for social media content.
AtlasScope involves rotating your camera 90 degrees so the sensor is in a vertical orientation and then mounting an anamorphic lens in the normal orientation. This combination allows you to utilize the maximum pixel density and fill the entire sensor.
By doing this with cameras that don’t offer open gate recording, like the Sony FX2, FX30, FX3, FX6, etc, you can extract a 9×16 image from a 1:1 master. It also allows you to deliver a 1:1 or 16×9 aspect ratio.
For monitoring, you also need to rotate an external monitor 90 degrees and then use a custom desqueeze with an inverse ratio to view the images correctly. Once you get the material into an NLE, you can then desqueeze it in the normal way.
