What is Nikon TTL?
TTL stands for Through The Lens metering. This is system where the camera measures the light on a scene based only on the light coming through the lens. Prior to TTL, there would be a light sensor on the top of the body (or a hand held unit) which measured the light coming from a fixed angle of view. The problem with this method is that it didn't take into account the angle of view of the lens in use. If a wide-angle lens was mounted, only the center of the viewed area would be used in exposure calculations, ignoring areas at the edges which could be brighter or dimmer than the center. When a telephoto (or long focus) lens was mounted, areas around the actually image would be included in the exposure calculation even though they are not included in the eventual image. TTL metering accounts for these differences by measuring light at the film plane. In more modern usage TTL is often used to refer to the flash metering system used by a camera. All of the same information applies. Nikon TTL is the Nikon camera company's version of the processing. The latest Nikon flash system is actually known as iTTL.
Interfacing of ttl with cmos and cmos with ttl?
whis is Endurance mors or ttl
Will an old-style flash still work on a Nikon digital camera hot shoe that has I-TTL?
Generally yes, but there are exceptions. It depends on the specific flash.
Which has a shorter propagation delay TTL or CMOS?
TTL
What is the full form of TTL?
TTL stands for Time To Live
What is the value of ttl set to in Tunnel mode for IPSec?
TTL is set to 40
What it the fullform of TTL in ping utility?
The full form of TTL is Time To Live
TTL logic is preferred to DRL logic?
TTL is faster and does not lose amplitude
Which logic family has the least propagation delay?
Here are the propagation delays for these gatesa) ECL = 2nsb) TTL = 1.5-33ns depending on the type of TTL. Conventional TTL is 9ns, Advanced Schottky TTL is 1.5nsc) RTL = 25nsd) CMOS = 5-20ns depending on if it is conventional CMOS, TTL pin compatible CMOS, high speed TPC CMOS or TTL compatible CMOSSo the fastest would be the Advanced Schottky TTL (74ASxx) at 1.5ns but the choice simply said TTL which I would interpret as Conventional TTL (74xx/54xx) which would have a propagation delay at 9ns.So the winner is ... (a) ECL which has a propagation delay at 2ns.
The main advantage of ECL over TTL?
The main advantage of ECL over TTL is speed.
What has the author Wilhelm Ho ttl written?
Wilhelm Ho ttl has written: 'The secret front'
Why is setting the TTL to a small number a bad Idea?
Because a TTL determines the maximum number of days the server will TTL of 0 means that the resource record should not be cached.
