Choosing the right flash setting can make or break a shot, especially in challenging lighting. TTL, or “through the lens” flash metering, is a powerful option for streamlining exposure in dynamic environments. This method lets your camera analyze light as it passes through the lens, using that data to adjust the flash automatically. For those who shoot in changing light conditions, like during events or outdoor sessions, TTL offers the advantage of quick adjustments without needing to dive into settings constantly.
