Nikon N70 instruction manual 127, Standard TTL Flash, TTL auto flash, Vari Program, Vignetting

Standard TTL Flash

A type of TIL auto flash that does not apply any automatic flash output level compensation. Flash output is controlled independently from the ambient light exposure measurement and, in most cases, illuminates a subject somewhat more strongly than with Automatic Balanced Fill-Flash, making the subject stand out distinctly from the background.

TTL auto flash

The camera'slight sensor measures flash illumination, as reflected by the subject on the film and shuts off the flash when measurement indicates correct exposure. Because the sensor that controls the flash receives light through the lens, TIL auto flash can be used for bounce flash photography, fill-flash, multiple flash photography, etc. An additional advantage of TIL auto flash is that you can use a wide range of aperture settings, while ensuring correct exposure.

With built-in flash or dedicated Nikon TIL Speedlight, the N70 camera performs Automatic Balanced Fill-Flash and Standard TIL Flash.

Vari - Program

Provides variable Programs for specific picture-taking situations. Eight Programs are available with the N70 camera. (See pp. 61-67.J

Vignetting

Progressively diminished illumination on the film from the center to the comers. There are two kinds of vignetting-natural vignetting caused by the lens, and vignetting that is caused by improper use of accessories such as a lens hood or filter.
