What is Canon E TTL 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. This is known as a flash metering system.
What is the difference between Ettl and TTL flash?
ETTL vs TTL Original TTL flashes read the exposure of the overall image straight from the camera’s built-in exposure meter and set the flash strength off of that reading. By contrast, ETTL first fires a few flash bursts to read the exposure while the flash is lighting up the subject.
What is the difference between TTL and iTTL?
TTL is used to generically refer to automatic Through The Lens metering, not necessarily even flash. The menus use it this way, to just mean automatically metered flash. 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 E-TTL II?
What Is E-TTL /E-TTL II? E-TTL stands for evaluative-TTL or ‘evaluative through the lens’ and it is a Canon branded technology that they use in their flashes. It is basically a form of TTL flash system they use in their digital cameras and E-TTL II is just a newer version of E-TTL.
What means TTL flash?
Through The Lens metering
TTL means Through The Lens metering. TTL flash uses a series or infrared flash bursts before the flash actually fires. This flash information is returned back to the camera which then adjusts the flash power accordingly to set what it thinks is a well-balanced shot.

What is the meaning of TTL in photography?
In photography, through-the-lens (TTL) metering refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter.

What is mean by TTL?
Time-to-live
Time-to-live (TTL) is a value for the period of time that a packet, or data, should exist on a computer or network before being discarded. For example, TTL is a value in an Internet Protocol (IP) packet that tells a network router when the packet has been in the network too long and should be discarded.
Should I use TTL or manual?
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. They switch to TTL only when they can’t change the flash settings fast enough for the way the subject is moving.
What does E-TTL do on a Canon EOS?
E-TTL is unique to Canon EOS cameras. All recent Canon EOS cameras run on E-TTL II. A basic description of what happens when we shoot in E-TTL mode:
What’s the difference between E TTL and E-TTL II?
E-TTL and E-TTL II are two generations of Canon’s flash metering scheme fgor digital SLR cameras. There are a number of differnces between them. The hope is that the E-TTL II system will more reliably, and over more circumstances, make a “better” choice of what output level to request from the flash than the E-TTL system.
When did Canon E-TTL II Flash come out?
E-TTL II was first released with the Canon EOS-1D Mark II in 2004. Improvements include taking into account lens-to-subject distance, does not weight metering to where the focus point is, and better deals with areas that could cause hotspots. Manually setting the power on a flash has the benefits of control, repeatability, and cost.
What’s the difference between TTL and a-TTL flash on Canon 35mm?
Canon’s 35mm film FD-mount cameras had TTL and A-TTL (took ambient light into account) Speedlites. When Canon switched to the EF-mount for EOS cameras, they took the opportunity to use a new protocol for communication between the camera and flash or flashes being used.
