TTL mode measures the light through the camera's lens and adjusts the flash power automatically. TTL flash can be convenient in fast-paced environments like weddings, where 'lighting conditions' and 'Distance from camera to the subject ' can change rapidly. It helps in achieving (nearly) fair exposure without constant manual adjustments. TTL is great for capturing candid moments where you may not have time to adjust flash settings manually. It is very important to keep in mind that TTL meter reading is calculated at the selected AF point. Hence, Prefer to use the smallest AF point possible to keep the TTL metering from being fooled. Ultimately, the choice depends on your comfort level and the specific requirements of the situation. Some photographers prefer the precision of manual flash, while others appreciate the convenience of TTL, especially in dynamic event environments. You can experiment with both modes in different scenarios to see which one aligns better with your shooting style and the results you want to achieve. Happy Refreshing.
