What is E-TTL II?
E-TTL was originally introduced in 1995, then updated in 2004 to E-TTL II, which is the current system. The flash system shares the light sensors in the camera’s viewfinder which are also used for evaluative metering of the ambient light. As the shutter button is pressed, an ambient light reading is taken.
What is the difference between ITTL and TTL?
And there was a short previous first Nikon digital try (until 2003) called D-TTL. But in reference to older film gear, TTL specifically specifies film TTL. iTTL metering method is modern digital TTL or TTL BL modes. TTL BL is balanced flash, which is the default flash metering mode of Nikon cameras.
What is camera flash E-TTL?
E-TTL mode, also known as E-TTL autoflash, is the mode where the camera uses information obtained through the lens (“TTL”) to calculate how much light the flash needs to emit for the appropriate brightness. The camera then automatically sets the flash output accordingly. This is known as a flash metering system.

What are Speedlite flashes used for?
Speedlite camera flash units enable you to add extra light to a scene and take control of how your subject is illuminated. They’re useful in low-light conditions but they can also transform images in bright sunny conditions by filling in shadows and helping to balance the exposure across the scene.
What is TTL flash Nikon?
TTL is used to describe any flash system that meters exposure Through The Lens. The Speedlight fires a series of pre-flashes to ‘test’ the scene, using the flash meter it can then calculate exposure just before firing the main flash to illuminate the subject during the actual exposure time.
Do I need TTL?
If you need HSS (high speed sync) then you want TTL. Manual flash is limited by your camera’s shutter speed. Typically 1/200s or 1/250s. TTL and a compatible camera allow a way around this to shoot at speeds up to 1/8000s.
What is Nikon ITTL?
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.
