ISO
Use the ISO setting to adjust the image’s brightness in the monitoring path.
The ISO range is ISO 250 to ISO 12,800. The default ISO is ISO 800.
Higher ISO values create brighter images in the monitor path, and lower ISO values create darker images in the monitor path.
When you record, the ISO settings are stored as metadata and you can adjust them non-destructively in post-processing with REDCINE-X PRO or other editing tools that support R3D files.
RED recommends setting the ISO to the default of 800, then adjusting the aperture and lighting to match. You can adjust the ISO later for fine-tuning.
