As soon as the photographer has decided to
take a flash picture, however, all he has to do is
set the small synchro-lever for action and his
next picture will be taken with a perfectly
synchronized flash. After the picture has been
taken, the synchro-mechanism is automati-
cally put out of action so that a new flash
bulb can immediately be placed in the re-
flector, even if the pictures which follow are
not intended to be taken with flash illumina-
