TTL Flash

TTL flash is a term used for auto flash setting. TLL, called Through-The-Lens flash metering, measures the amount of light coming in through the camera’s lens and adjusts the flash’s exposure or power with the goal of creating an evenly exposed image.

Most flashes have a TTL mode. You can find an on-camera flash for your DSLR HERE.
