- Part of the Microprocessors glossary: Transistor-transistor logic (TTL) is a digital logic design in which bipolar transistor s act on direct-current pulses. Many TTL logic gate s are typically fabricated onto a single integrated circuit (IC). TTL ICs usually have four-digit numbers beginning with 74 or 54.

The TTL Flash System Flash key is where the light from the flash is the main light. Flash fill is when the light from the flash is filling in the deficiencies in the ambient light, in other words, filling in the shadows. The Nikon TTL flash system is more than capable of handling both of these situations without any help from us.

Phottix introduces Canon RT version of its battery-powered Indra500 TTL studio flash head Phottix introduces Canon RT version of its battery-powered Indra500 TTL studio flash head. Flash and accessory manufacturer Phottix has announced a new version of its Indra500 studio head that has a built-in TTL radio receiver for Canon’s RT flash system. The new head can be controlled directly from a Canon RT radio Speedlite in the hotshoe of a compatible camera or by using a Canon ST-E3 or Phottix Laso transmitter instead.

DSL Stands for Digital Subscriber Line.. DSL is a communications medium used to transfer digital signals over standard telephone lines. Along with cable Internet, DSL is one of the most popular ways ISPs provide broadband Internet access. When you make a telephone call using a landline, the voice signal is transmitted using low frequencies from 0 Hz to 4 kHz.

TTY/TDD TTY/TDD stands for a group of telecommunication devices that make it easier for deaf and/or mute people to talk over telephone lines. TTY stands for telephone typewriter, teletypewriter or text phone. TDD stands for Telecommunications Device for the Deaf. Usually these devices are all categorized under TTY/TDD. Sometimes TTY means manual devices such as typewriters, TDD devices usually fall under computer assisted or digital devices. For the most part, a TTY/TDD device is the size of a typewriter or a small computer. The vast majority of these devices have a QWERTY keyboard and some sort of display screen that either uses LED, LCD or other display technology.

What does TTL mean? TTL stands for Through The Lens, and in the case of SLR metering, it indicates how the light is measured--that it's the light coming through the taking lens, rather than, say, an exterior sensor.

DWI Lawyer's Advice For Drunk Drivers Could Scare You Sober (Update) Mitchell: First we have to understand what No Refusal weekend means. That doesn't mean you're not allowed to refuse the test from the police officer. You absolutely keep your right to refuse field sobriety tests, the breath test, and the blood test, even when they say it's a No Refusal weekend. What happens when you refuse a breath test or you refuse to consent to a voluntary blood test, the police officers have to detail probable cause on a search warrant, and a magistrate has to approve it. Typically, the magistrates are City of Austin municipal court judges. Obviously if you do a field sobriety test, that's one way they can get probable cause.

What is TTL and non-TTL A non TTL automatic flash you tell your flash what aperture and ISO you will be using then the flash will compute a flash output based on how much light is available. An adjustable manual flash, you set your flash output manually based on what aperture and iso settings you are using.lkka wrote: It is a bit simplistic to just say that 'TTL is better', because all studio flashes are not TTL and are often quite obviously better sources of light than a small flash unit made by the camera manufacturer.. TTL is a flash metering technology for cameras-not camera lighting.

Using External Flashes in the TTL Mode We suggested that the external flash be set to the TTL mode. The TTL (i.e. , T hrough T he L ens) mode means that the camera will measure the output of external flash and stop the flash once illumination is sufficient.This is the easiest mode of using external flashes.However, do keep in mind that the Coolpix 990 is not true TTL cameras in terms of flash control. It measures flash illumination with a flash sensor next to the on-camera lens as shown below. As a result, what this sensor sees is usually not what the lens sees.his is the easiest mode of using external flashes. However, do keep in mind that the Coolpix 990 is not true TTL cameras in terms of flash control. It measures flash illumination with a flash sensor next to the on-camera lens as shown below.

Teletypewriter overview A teletypewriter (TTY) is a data terminal that people who are hearing impaired or speech impaired can use to transmit and receive text through a telephone system. A TTY is also referred to as Telecommunications Device for the Deaf, or TDD. The term TTY is preferred because not all users are deaf.

Bacillus megaterium Bacillus megaterium is a gram positive, endospore forming, rod shaped bacteria. It is considered aerobic. It is found in soil and considered a saprophyte. Bacillus megaterium is latin for the big beast because it is an extremely large bacteria, it is about 100 times as large as E. coli.Due to its immense size, about 60 micrometers cubed, B. megaterium has been used to study structure, protein localization and membranes of bacteria since the 1950’s.Most notably, B. megaterium is the organism that was used by Lwoff and Guttman in the studies that discovered lysogeny.ue to its immense size, about 60 micrometers cubed, B. megaterium has been used to study structure, protein localization and membranes of bacteria since the 1950’s.

- Flash metering is through the lens, using the camera's metering system, which looks through the lens you're using. Non-TTL means the flash doesn't communicate with the camera in that way, and instead uses its own light metering system, built into the flash.TTL is better!lkka wrote: It is a bit simplistic to just say that 'TTL is better', because all studio flashes are not TTL and are often quite obviously better sources of light than a small flash unit made by the camera manufacturer..

- The original concept of TTL is sometimes referred to as standard TTL.. Many modern flash units also have the ability to use a setting known as advanced TTL.. In advanced TTL metering, the flash unit fires one or more pre-flashes of either infrared or white light before exposing the film.he advantage of using a through-the-lens flash metering system is that the photographer is not required to perform the calculation of flash output, which eliminates a margin of error.
