For distributors, the important distinction is format and intent: a poster is a clinician reference; a software overlay is a precision layer that must align exactly with an image captured by the iriscope. Treat these as different deliverables with different technical requirements. Distributors must confirm these capture variables with their camera supplier and with the map provider: Native camera resolution — confirm the camera’s sensor and maximum output. Without these checks, an overlay will sit off-centre or misalign with radial markers, making annotations misleading for training or records.
