What is E-TTL and I TTL?
Generally speaking, the three acronyms all essentially refer to the same electronic mechanism by which flash works for all three brands. E-TTL = Evaluative “Through the Lens”, i-TTL = Intelligent “Through the Lens”, P-TTL = Preflash “Through the Lens”. All three are pre-flash based evaluative flash metering systems.
What is the difference between TTL and iTTL?
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.
Is Ettl the same as TTL?
The TTL (“through the lens”) method used sensors inside the camera body that measured the light reflected off of the film, which would detect lens aperture, any filters, etc., and then cut the flash output as soon as the exposure had been reached. ETTL is completely different.
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 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.
What is E TTL II?
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. All recent Canon EOS cameras run on E-TTL II.
What does Ettl stand for?

Are Godox flashes any good?
Build Quality, First Impression. When it comes to build quality, these flashes are built significantly better than what I remember from three to four years ago. The Godox XProC Remote still feels a bit light and cheap in its design, but the flashes themselves are significantly more solid.
What is the difference between E TTL and i TTL flash?
Generally speaking, the three acronyms all essentially refer to the same electronic mechanism by which flash works for all three brands. E-TTL = Evaluative “Through the Lens”, i-TTL = Intelligent “Through the Lens”, P-TTL = Preflash “Through the Lens”.
What is the difference between TTL-BL and TTL-FP?
TTL-BL is a separate mode for fill flash. For successful operation, it requires that subject is darker than background, and works to brighten it to balance with the background. TTL-FP is Nikon’s term for high speed sync. Similar to FEL in E-TTL, FV Lock can be used to perform preflash metering in advance.
What is P-TTL flash metering?
Similar to others, P-TTL meters a low power preflash with lens wide open before opening shutter and calculates needed flash power level. There does not seem to be any way for triggering preflash metering manually. With a P-TTL flash turned on, exposure compensation is applied to both ambient and flash exposure.
How do I use multiple flash groups in TTL mode?
Each group can be instructed from master flash to fire in TTL (you can also adjust flash exposure compensation for the group) or at a manual power setting. Also, there are 4 channels available to enable multiple photographers use each their own flashes. TTL-BL is a separate mode for fill flash.
