It's not film. So long shutter times may not help. The sensor does not behave like film which can confuse those that are jumping from film to digital cameras.
Yes, at first the time helps as light fires up the sensor cells but unlike film as time passes the sensors degrade or forget to something that looks just like noise.
Does that help you understand?
so yes i've been looking everywhere for a list of the shutter speed for cameras but i cant seem to find it anywhere so i end up making a topic here. i've been looking for a camera, around the budget of i guess US $400 with the option of having a shutter speed of more or around than 30 seconds(preferably around 60 seconds). i currently have an olympus c-770 and it although produces nice images, the value for its longest shutter speed is only 15 seconds and i dont like it
so do you guys have any recommendations? thanks in advance!!
p.s. will i have to buy a SLR camera to get that kind of shutter speed?
