What is the difference between iTTL and 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 the difference between TTL and Ettl?

The TTL flash then produces a flash that corresponds to the reading. The ETTL is much more advanced than the TTL. Instead of obtaining the reading from the camera exposure meter, the ETTL fires a pre-flash to obtain exposure from the subject.

When was TTL flash invented?

The first TTL light metering SLR was the 1963 Topcon RE Super, which had the CdS metering cell placed behind the reflex mirror.

What ISO should I use with flash?

Working with Flash means that we usually have plenty of light available and that allows us to work with the lowest native ISO of the camera, which in most cases would be ISO 100. This will give us the best dynamic range and image quality. The aperture affects the depth of field.

What does E-TTL stand for?

E-TTL stands for Evaluative through-the-lens and is a type of autoflash exposure system used by Canon. E-TTL was originally introduced in 1995, then updated in 2004 to E-TTL II, which is the current system.

What will happen when you shoot faster than the camera sync speed?

If your camera’s flash sync speed is 1/200 and you shoot at a faster shutter speed than that while using a flash, your shutter will close before the flash can be fully captured by the sensor, resulting in black bands in the frame where the shutter can be seen.

What does f mean in photography?

The “f” in f-stop stands for the focal length of the lens. While focal length itself refers to the field of view of a lens, f-stop is about how much light you allow to hit the sensor via the aperture opening.

How far can a 600mm lens see?

Are you asking the minimum focusing distance of that 600mm lens? If so the answer is about 15ft. If you mean how far away can it shoot distant objects then that depends on how big they are and how big you want them to be in the final image. It also depends on whether you are using a Full Frame or APS-C camera.

Is a higher focal length better? The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification.

What is the zoom setting for on a speedlight?

The zoom setting on your flash sets how disperse or narrow the light coming out of the flash head is. The head actually moves up and down within the flash unit as you change the amount of zoom. When you use wide angles, the head is near the top of the flash so that the light is free to come out in every direction.

What does mm on flash mean?

How do you shoot with a speedlight?

How do you read flash powers?

How many speedlights do you need?

My my experience as a photographer specializing in industrial, B2B, and editorial work is : at least two 500 to 640 watt-second MONOLIGHTS and. 4 to 6 speedlights. I also need to say I rarely use all of the lights I take to job or have on set, BUT IT REALLY DEPENDS ON WHAT YOU PHOTOGRAPH AND HOW YOU LIKE TO LIGHT.

Do I need speedlight? Adequate lighting is crucial to achieving properly exposed shots, and sometimes, you’ll need the help of additional light sources if the scene isn’t bright enough. The speedlight or “flash gun” makes a portable and useful option for this.

What should I look for in a speedlight? 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 does E-TTL stand for on a flash?

E-TTL flash metering: The function that measures the flash output needed for correct exposure. In Start Flash Photography in 9 Steps, we learned that there are two flash modes you can use: E-TTL (Evaluative Through-The-Lens) mode or Manual mode.

What is E-TTL mode?

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 manual 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 on speedlight?

TTL means Through The Lens metering. When you focus your camera with that half push of the shutter, your camera is not only focusing, but its taking a reading (metering) of the scene. It is taking a measurement of how much ambient light is being returned Through The Lens to the sensor.

What ISO is too high?

A low ISO value (e.g. 100 or 200) means low sensitivity to light. This is exactly what’s needed in bright conditions in order to avoid overly-exposed photos. A high ISO value (e.g. 800, 1600 or higher) means a high sensitivity to light.

Is lower ISO always better?

When you use low ISO values such as 300 and lower, generally the result is a higher quality photo. Bright conditions — like shooting outdoors on a sunny day — benefit from lower values. Landscape photography, for example, is very well-suited to low ISO values. They keep photos from looking overly-exposed or washed out.

Does shutter speed matter when using flash?

Shutter Speed (Almost) Doesn’t Matter

A flash will provide a burst of light that only lasts for a fraction of a second, somewhere in the realm of 1/1000 second or faster for most flashes. If your shutter speed is at 1/250 second or 1/50 second, both exposures will receive the full power of that flash.

What is a TTL flash? 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. In practice this works fairly well, but what you end up with is often less than desirable.
