I've been shooting with a Leaf 65 back for sometime now. I've always had great results with an ISO of 50 - 200, with a fair bit of noise at 400 and especially 800. On the flip side, I've never shot over a 1 sec exposure as I've always heard that anything more than that is just asking for a *lot* or noise. Recently though, I'm seeing a fair amount of posts that boast longer exposures (30 sec +) with great results. (I think the Phase backs win the prize there from what I've read.)

How do the noise results compare with ISO 50 @ 15sec. verses ISO 400 4sec? This is something I've never tested out, but it's been bugging me for awhile. Given the choice, do you go for a higher ISO, or longer exposure?

Thanks.

Wouldn't that be very simple for you to check yourself?

it is basically always better to shoot at lower ISO with longer exposure than the contrary.

Best regards,

I would agree with Thierry, but it will also depend on which back you are shooting with. Certain backs can not do long exposures and will fall apart when pushed to their limits. I would definitely
test to see what your particular back can do.

I will definitely try it out now that I know that long exposures won't damage anything.

Thanks.
