My second attempt at a time lapse video fared as well as the first – not good. For some reason my 60D makes drastically different exposure decisions in low light. I don’t have this problem when I shoot regularly, it only seems to be a problem when using the intervalometer. I should also note that I forgot to set the ISO to a reasonable setting before starting the time lapse so the first half was taken with ISO 100 then in between shots I switched it to 200, 400, and finally 800. I don’t think this had any affect on the outcome (as in, it would have made no difference if it had been left on 800 for the entire time). My camera just sporadically meters poorly when taking pictures at intervals in low light conditions. The following movie looks much like the previous.
