Not really, metering just becomes unreliable which I guess you could say is similar but more to do with the lack of light. An exposure like the one above is fine and plenty bright eough. You just need to shoot at -1EV to -1.7V to compensate for the fact the the meter wants to include the dark bits but you need to expose towards the brighter bits. That's the subject matter, not the lenght of exposure.Peter,
A question. I'll probably show my age here but I'm curious.
In the old daze, there was a thing called film. With this acetate coated material, it had reciprocity. Do you find any reciprocity effect with your digital camera and if so, what percentage?
