iPhone Multi-focal, aligned at eyeline
Phase 1 / Evaluation test for Michael Glass and Andy Ward
The first phase of the evaluation focuses on analyzing the eyeline and the effect of a teleprompter positioned just below.
a 3D beam splitter. The goal is to create a seamless, natural eyeline that remains completely invisible to the viewer.
Our approach to aligning the eyeline with multi-focal length lenses involved the following setup:
• Two iPhone 16 Pro Max devices recording in Apple ProRes 4:2:2 HQ.
• A DoF adapter paired with Zeiss lenses, utilizing a wide 35mm focal length and a longer 100mm focal length.
• Both iPhones were mounted on a 3D beam splitter rig.
• Subject was positioned 10 foot away from the 3D beam splitter.
• An iPad Pro 12.9" was mounted just below the beam splitter to serve as the teleprompter.
At this stage, the primary focus is on perfecting the subject's eyeline and their ability to read from the teleprompter
Without the viewer noticing. Improving the image quality-impacted by the use of DoF adapters and shooting through
The beam splitter~has not yet been prioritized.
These enhancements, along with overall image quality improvements, will be addressed in phases two and three,
Where additional time and resources will be allocated to refining the results.

Camera Tests
As discussed, the focus of this test was to capture eyeline consistency across multiple focal points while ensuring the teleprompter had no impact on maintaining direct, natural eye contact with the lens. Most importantly, all footage was captured using iPhones. We will to add quality improvements from mounting a lens adapter on an iPhone, this will be part of phase 2 with more resources and time.
