P3D Nimslo Uderexposure

[markaren@xxxxxxxxx (Karen Obusek)]

I just reviewed my Nimslo specs and maybe I'm not understanding this too
well, but the photo sensor seems to be bottom weighted by 5 degrees ( no
big deal....however this may explain brighter foregrounds underexposing
the images) The specs also state 24 degree semi-angle which I don't
quite understand. If the sensor has a field measurement of 24 degrees,
this would approach spot metering performance. 24 degrees measured from
where? The entire sensor field of view? 24 degrees in any direction from
the center axis? Could someone clarify this? I am lead to believe the
Nimslo has very narrow metering and meters slightly below center
horizon. This really changes ones approach to composition for slide film
use. If this is correct....I would have to carefully think about every
shot!! :-(  Yikes.....where's my Realist and light meter! :-)
