What does E-TTL mean in photography?
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 TTL and E-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 HSS flash?
High Speed Synchronization (HSS) is a function that allows the camera to use fast shutter speeds with an external flash. Cameras have a limited flash sync speed; this means the fastest shutter speed that can be used with a built-in flash is generally 1/125 to 1/250 second depending on the camera.
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.
Does TTL work with HSS?
If you need HSS (high speed sync) then you want TTL. TTL and a compatible camera allow a way around this to shoot at speeds up to 1/8000s.
What is Canon Speedlite used for?
Lighting objects from the side is a great way to highlight texture, add drama, and cast interesting shadows. One can employ off-camera flash by simply holding the flash at arm’s length to one side or above. With multiple Speedlites, photographers can create studio-like portraits with hair, edge, main, and fill light.
How do I choose a Speedlite?
The most important factor when choosing a speedlight, however, is how much distance you’re likely to cover. You should also consider whether the head rotates — the more rotation, the more control you’ll have over softening or changing the angle of light falling on your subject.
What is Ettl mode?
When should I use TTL mode?
You might use TTL for one scenario and manual for another. TTL flash is excellent in scenarios where the distance between the flash and the subject changes fast. If you are photographing a wedding processional on manual flash mode, the lighting will change as your subjects get closer to you.
What does E-TTL stand for in Canon flash?
Hi Amy, E-TTL is Canon’s acronym, meaning evaluative through the lens. TTL is the generic through the lens abbreviation. Your EOS 100D can work with any Canon Speedlite flash with the letters EX in the name.
When did Canon EOS TTL 2 come out?
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.
What kind of lenses are compatible with E-TTL II?
Non-current lenses which should return distance info include the non-IS telephoto lenses such as the EF 500/4.5L USM, 300/2.8L USM, 600/4L USM Note that E-TTL II does not use distance information when a direct, camera mounted, flash is not used, even with E-TTL II compatible lenses.
What does TTL stand for in camera category?
TTL stands for Through-the-Lens, and applies to several camera features. The most notable features are that you see through the lens when you look into a viewfinder and light is also metered that way. SLRs, DSLRs, and digital mirrorless cameras allow you to see the frame that will be captured through the lens.
