Voigtlander Vitessa Exposure Meter User manual

The exposure meter is very sensitive
ond covers o lorge brightness ronge.
The even spectrol sensitivity of the
photocell permits occurote deter-
minotion of light volues with ony
of the more usuol light sources.
A grid system limits the ongle of
occeptonce of the photocell to ihe
ongle of view of the comero lens.     n s.1

Toking lhe Reoding['
     When toking o reoding (see nexi poge) toke core not to obscure the window of the cell O.
I     The red tip of the pointer vrill then point to either o block or o white sector on the scole @.
       Troce to the left from the sector, ond reod off the oppropriote light volue on the drum @.
           lf ihe red tip of the pointer points between two sectors, you con set fhe shutter to the
       oppropriote holf light volue, ond get the most exoct exposure possible.

Artificiol Light Shots: To ovoid misleoding light volues due to direct light from lomps
      folling on the cell, it is odvisoble to toke close-up reodings.

b.      lnteriors: lf the light source is behind the comero ond no windows ore included in the
       field of view, use one light volue higher thon given by the meter.-                                -                                          ilntn/rr.butkus.uS
     Shof with Filters: After toking o reoding, odiust the light volue to ollow for the filter
       foctor. For o filter with o foctor of 2 reduce the light volue,by one; with o foctor of lrlz
      or 3 reduce the light volue by holf or one ond o holf respectively, ond so on.

     Colour: Toke exposure reodings in the some woy os with block-ond-white. Remember
     however thot the exposure lotitude of reversol c,olour film is very much smoller ond
      therefore the light volue must b'e determined porticulorly corefully. While fhe correction
