[LargeFormat] Snowy Landscapes

[Hornford, Dave]

Snow is more reflective than a 'neutral background', and won't give a true
zone V value on metering. If I can I meter something else in the same
lighting (hand, trees, some rock) then apply the adjustments to move the
snow to Zone VII. If I have to meter snow I assume the reading is 2 stops
above a 'neutral background' - experimentation has shown a bit of variation
whether the snow is under cloud, in shadow or in full sun)

regards Dave

If the snow is your most important subject, and you want the snow to be
fully textured (Zone VII) than the metered value of the snow (Zone V) + 2
stops open should do it for you (VII - V = +2 stops open).  Let the other
zones just be where they are; not much you can do about them anyway.

1/3 - 1/2 stop up or down may be a fine tuning.  Also depends on your meter.
A UV or Skylight filter will cut down on the bluish tint (mostly from
(invisible) UV light exposing the blue sensitive layer unproportionatly
more).  No exposure adjustments are necessary for those filters.

In the UK it has been snowy the last few days and I have been out with
my Pacemaker Speed graphic 4x5 shooting 100ASA Provia using a Weston
Master IV for metering - the question is how much should I bias the
exposure for a snowy scene?  I'd been guessing about +2 stops but unlike
35mm braketing is not practical - any general rules of thumb?

Regards and Thanks
