What is Canon E TTL E TTL II?
E-TTL flash metering: The function that measures the flash output needed for correct exposure. This is known as a flash metering system. Different camera manufacturers use different versions of TTL flash metering. E-TTL is unique to Canon EOS cameras. All recent Canon EOS cameras run on E-TTL II.
What is the difference between iTTL and TTL?
TTL is used to generically refer to automatic Through The Lens metering, not necessarily even flash. But in reference to older film gear, TTL specifically specifies film TTL. iTTL metering method may be TTL or TTL BL modes. TTL BL is balanced flash, which is the default flash metering mode of Nikon cameras.
What is the difference between TTL and non TTL flash?
Using TTL automatically adjusts the flash output for you as the distance between you and the camera changes. Manual flash is best in scenarios where you want the most control over the light source. It’s also useful if the distance between the subject and the flash doesn’t change rapidly.
What is TTL Nikon?
The best part is that Nikon Speedlights are really easy to use, with a full automatic mode, called i-TTL, or Intelligent-Through-The-Lens metering. This means that the camera and flash will communicate with each other and figure out the best exposure that will balance both the subject and the ambient light.
What is Nikon TTL?
TTL is used to describe any flash system that meters exposure Through The Lens. Nikon use the term DX as a suffix for Speedlight names that support the pre-flash function which is an essential element of D-TTL operation. i-TTL – Is an evolution of D-TTL that incorporates more accurate systems for pre-flash.
What is the difference between TTL and HSS?
Using the TTL setting gives you a convenient set it and forget it way of shooting, but there are some limitations including the maximum sync speed. HSS, on the other hand, lets you use your flash at far higher shutter speeds, but with some tradeoffs.
What is the difference between TTL and Ettl?
The ETTL system uses a preflash before a photo is taken to improve the quality of the exposure. This allows for the same evaluative metering sensors to be used that are used for ambient light. TTL and A-TTL flash modes use a dedicated flash metering sensor.

What is Canon E-TTL II?
With E-TTL II, the control over exposure was moved to the firmware inside the camera body. This allows for additional calculations to be done and removes the need to provide firmware updates to an external flash. E-TTL II was first released with the Canon EOS-1D Mark II in 2004.
