photographic speed वाक्य

उदाहरण वाक्य

1. This very greatly increased the photographic speed ( light sensitivity ) of the film.
2. LIRF is due to inefficiency of forming a latent image, and this reduces photographic speed but increases contrast.
3. It was also found that, when developer solution is optimally formulated, the maximum photographic speed is rather insensitive to the choice of developing agent ( James 1945 ), and there exists a limit for the size of silver cluster that can be developed.
4. Thus there is a limit in increasing the photographic speed of the system by boosting the developer potential; if the solution's reduction potential is set high enough to exploit smaller silver cluster, at some point the solution begins to reduce silver halide crystals regardless of exposure.
