Claim 14:
15. A welding mask display system, comprising:
a high-dynamic range (HDR) camera subsystem to:
select an exposure time as a submultiple of an operational frequency of a welder,
generate HDR frames of an HDR video using at least one image captured with the selected exposure time,
receive data identifying an operational frequency of the welder, and
select the exposure time of at least one image used to generate each HDR frame of the HDR video as a submultiple of the identified operational frequency of the welder;

an optical filter to attenuate at least some wavelengths of optical radiation; and
a digital electronic display to display the HDR video to an operator,
wherein the HDR camera subsystem is configured to generate the HDR video with a frame rate that is a submultiple of the operational frequency of the welder.
