I have heard about pointing a CdS meter at a bright light source before reading a dim source to speed up the response.

What do I do if I am eyeing an illuminated church at night but only get about an EV5 off the highlights? I only want the highlights and some detail of the bell tower, but the bright source isn't enough to 'pump up' the photocell.

I notice a few-to-several second drifting of my analog Pentax 1/21 spotmeter on low levels, but I'm happy with the stability after this period of time. I haven't waited 3 minutes to see what happens, as the manual mentions.

Does one need to compensate in some way with such a meter and low levels, knowing readings will be inaccurate? (Ignoring reciprocity failure which isn't mandatory at EV 4-5).

Thank you
