Dear John,Thanks to everyone who has replied. Very kind but there is a great deal of conflicting advice...
Meter from shadows/ don't meter from shadows
don't use meter/do
red filters will darken shot
grey card/ not grey card
incident/reflective/spot
grass/hand
As I have said, I am really grateful for the advice. It has helped but to firm it up could someone answer the following questions in a non theoretical and concise way.
1 If I take a black and white shot using hp5 with a red filter of a landscape scene where top third will be bright sky with the sun behind me on a bright day what would I meter and where would I meter from
2 as above but yellow filter
3 As 1 but a building
4 As 2 but a building
5 Would the answers to 1-4 change on an overcast day?
Many thanks
John
Favour the shadows (point the meter more towards the shadows/dark areas) with either landscape or building. This is the basic advice and all you really need.
With a red, orange or yellow filter the shadows will be even darker on a sunny day than in an unfiltered shot because they are lit by blue skylight not white sunlight, and 'contrast' filters darken blue. Meter anything else and you risk losing shadow detail.
The red filtered shot will be contrastiest (blue shadows). Consider an ND grad filter. Also consider that some meters are excessively sensitive to red and may recommend underexposure.
No, it doesn't change on an overcast day. The subject brightness range will be reduced but the shadows still remain shadows and may block up unless you favour them.
A LOT depends on what sort of meter you are using. TTL? Hand-held? What sort of meter cell?
You cannot invariably rely on either incident or a grey card (exposure keyed to highlights) because both completely ignore the shadows. On an overcast day, film latitude will save you. On a sunny day, it won't. Incident is ideal for slides and digital (exposure keyed to highlights) but NOT for negatives (exposure keyed to shadows).
A 'non-theoretical' answer is impossible because (a) the latitude of B+W film covers a vast range of errors, fads, misconceptions and internet drivel and (b) ANY method of metering (even grey cards and incident metering on sunny days) can be made to work with the appropriate 'fudge factors'.
Although it's not about metering, you might also care to look at http://www.rogerandfrances.com/subscription/ps ignore gurus.html "Gurus and Why to Avoid Them".
Cheers,
