Great. I have tried it out yesterday night, and one particular experience was that while i was at the esplanade concourse area trying to capture a good esplanade scenery, at F22 and 30", my spot meter read at around 20% underexposed, thus i experimented with bulb mode at various longer shutter speed, guys, how long do you think would be good.
Secondly, with a tripod and at long shutter speed, why do we still need a cable release, not as if straight after we release the sutter we leave it dere until the shutter shuts ? I understand that in bulb mode we have to use shutter, but not in bulb mode? is it still a must? Hopefully my pics turn out okay.
Once again, thank you guys for the precious comments and pardon me for being amatuer to asking the stuffs.
