One of the most importont prerequisites for successful photogrophy is to
ensure thot exoctly the right quontity of light folls on the film. In-generol it is
9f ng im.portonce, where ihe correct degree of blockening to be-undergonebv tbq. film. is _conce.rned, .whether the ioid quontity of li"ght is obtoinel by providing the film with o little light over o long period or whether it receive's

IMPORTANT FOR THE OWNER OF AN AKAREX TOOL:
The quontity of light emonoting from the subiect selected ond impinging on

exposure volue meter.
T-he p-rinc_iple of modern exposure volue odiustmen! is to.express ihe quon-tity of lighr    hoving due regord to the sensitivity of the film     in one singlenumber, the- socolled exposure vqlue.                        -
This exposure volue number    or exposure volue, for short     is reod off onthe exposure volug meter, ond- the shutter of the comero is then-  odiusted to  it.
The mechonism of the shutter ensures thot for o given"of  exposure volue seftingihe film olwoys receives the sqme quontity      lighi. li does this bi

closing up the diophrogm when o longer exposure time hos been selected,
so thot the light con only enter through o very smoll opening, ond by provi-
ding o wider lens operture in the cose of short exposure times.
The result is thot the blockening of the negotives is uniform.
This coordinotion between exposure time ond diophrogm in the exposure
volue shutter enobles the user to operote ropidly ond without unnecessory
mentol effort. This opplies porticulorly to colour photogrophy, which colls for
occurote exposure qnd ollows of comporotively  little morgin in this respect.
