1.      As a result of this calibration  a medium grey tone will be reproduced by black and white as well as colour film with a  density or colour value  respectively that lies approximately in the middle of the straight line of gradation  Thus   sufficient latitude exists in correct exposure for those parts of a scene which are lighter or darker than the  medium    grey      Reciprocity Effect   Film manufacturers base the  speed ratings  of photographic emulsions on average conditions of exposure times and  illumination under which such emulsions are  normally  intended to be used  However  photography under poor light  conditions may call for  abnormally  long exposure times     Black and white films  generally  tolerate moderate deviations from normal conditions  On the other hand  reversal  colour films   because of their limited latitude   not only lose  speed  but their colour balance is also affected    The reason for this divergence lies in the fact that the effective sensitivity of every photographic emulsion is at a  maximum at some specific level of illumination  With variations in illumination and exposure time  the effective  sensitivity also varies  a phenomenon which is called the  reciprocity effect      Film of various types and makes react differently to extended exposure times  and it 1s impractical to incorporate the  many possible variations in the LUNASIX 3 scales  It is advisable to write to the film manufacturer for information  concerning the necessary
