p.15 #16 · Your Best Nightscapes and how they were made | |
I have seen great photos here,
There's 1 thing that i don't quite understand...
there's a picture which taken for 25 minutes, and i've seen on early pages there's 1 photo in which taken for 4 hours...
i know they are using the bulb, but what i really want to know...
how do they know whether they need 25 minutes or 4 hours exposure....
in-camera only allow until 30 second as i remember, that is an easy one 'coz i can see the metering within the camera, so i know that this will come out great.... it would be different with using bulb for fireworks too.
i have no remote, so i only know bulb from the forum ... but yeah, how can you meter using bulb?
i hope i don't confuse everyone... thank you!
On technic that I use is to shoot at the highest ISO in your camera (mine is 6400) at the highest aperture (f4 for example)...do some trial and error and then the math to go back to ISO 100 f8. For instance if the shoot I got at f4 ISO 6400 for 1 minutes is OK, then I will do ISO 100 f8 (1minutes x2x2x2x2x2x2 for ISO, x2x2 for apperture = 256 minutes!)
