I remember reading that Swarzild's rule (?) (=reciprocity failure) applies
to multiple short exposures as well. 1000 x 1/1000s is NOT same as 1s...
(Actually, one photographer DID that thousand exposures!!! Must have been
very tiring... he photographed Wenceszlaw's square in Prague, lots of
traffic and people). He found out that he needed MORE exposures that just
thousand of 1/1000s.
BTW, if you ever come to Prague or any near, try to look at one book:
Jan Reich, PRAHA
These are contact prints from his 5x7" camera, of Prague streets COMPLETELY
devoid of both CARS and PEOPLE. As few may know, Prague has a very nice
jewish quarter and a lot of very old streets (although now it's quite
spoiled by tourism... the crowds everywhere and the ads there too ;-/ ) And
he DID NOT use time exposure (or 1000x1/1000s) to get rid of people on all
his pictures. He sometimes simply selected such days and times when there
very very few people... you can tell on some of the pictures from shadows -
they are sharp, having not moved between the exposures as they would with
long exposure.
