I have experienced in my very recent experiments with low light photography. Basically, I have found that my DSLR has a tendency to underexpose quite significantly - the darker the conditions, the more it underexposes. I mentioned the problem to Roger B and he suggested that my camera might be limited to a maximum value of 30 seconds for time exposures (as is the case with his). Well I have checked and sure enough the maximum length exposure time I can get in Av, Tv or metered manual is 30 seconds, which very probably explains the issue. Is there any way round this other than to resort to using the B setting and trial and error? What do other people do with regard to metering if they want an exposure that runs over several minutes?
I didn't find the right solution from the Internet.
