Aug 20,  · Canon’s DSLR cameras use a pre flash to determine the correct flash exposure, a system known as E-TTL. Way back in time, Canon EOS film cameras used a system called TTL flash where the flash was metered off the film surface during the actual exposure. Several of . Nikon’s i-TTL (intelligent through-the-lens) flash system meters every exposure, setting the Nikon Speedlight’s output to the precise level needed to balance the scene’s ambient light. Recycling Time. The time necessary for an electronic flash to recharge and be ready for the next picture, it often depends on the type and condition of the. In flash metering terminology, a TTL system in the camera/flash combination typically means that the camera will tell the flash to send out a small "pre-flash" burst of a known brightness level, meter that flash, and then automatically adjusts the flash power to where the camera's exposure system thinks the power needs to be for good subject.

It can be of any type, generally, without specificity. For example, a flash menu may say TTL (general automatic flash), but it means it does what the metering system is going to do, which may actually be iTTL (a specific type of general TTL).INON S-TTL Auto supports any manufactures' model with its highly accurate exposure .

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. In some cameras various TTL metering modes can be selected. Some early Pentax DSLRs could use this same configuration for TTL.
