I need to ask the user to clarify what each part refers to. They might be using a specific format or code that's not widely recognized, so more context will help provide an accurate answer. Also, mentioning that "003" is part of a series could be important if there are multiple versions.
When applied to a shoot like the one featuring Carina Zapata, TTL implies a dynamic, adaptive lighting setup. Unlike manual flash, which requires the photographer to calculate distance and aperture manually, TTL flash metering allows for rapid changes in the shooting environment.
