Yes I mean that the photographer has to decide what is 18 0rey by
experience (eg grass, tarmac depending on reflections) or by using a card.
To assess all the zones in a picture I mean taking spot readings of each
zone. While taking
multi-spot readings the camera does automatically average them. The
readings display will
give you the range of exposure values in the scene, each spot reading and
the average are displayed on the viewfinder LED.
You can use the multi-spot readings to emphasise one particular exposure
level, as described above.
The aperture can be changed in (multi)spot mode whilst maintaining the
correct exposure (the camera changes the shutter speed).
The OM4Ti brochure, if you can get hold of it, does describe multi-spot
metering quite well (better than this!).
NB I recommend that if you decide to buy an OM4 you get a Ti, there is no
problem with battery drain (I find with Panasonic they last for ages).
>Richard, don't read my puzzlement as diminished appreciation of your
Thanks! Still the best way is to borrow one and have a play yourself, its
easier than trying to describe in words. Its like a manual for a VCR, seems
more complicated than it is until someone demonstrates it.

If you do expose for a back lit subject (eg on the face), the background
may be overexposed, fill-in flash is the only answer if you wish to avoid
that (theory only never used it myself though).
Hope this helps
