How to favour exposure time over ISO?
So let’s start the ball rolling. This is a question that has been asked in many different guises on the TLV FaceBook page.
Supposing we know what the final exposure should be for a night exposure (good old 500 rule) and we want to keep the ISO as low as possible, how do we config that?
In my experience I often end up with an exposure time lower than my target and an ISO that is higher. The overall exposure is often correct.
it depends actually on what kinda timelapse you try to make. And the conditions you are making your timelapse , clouded or not , dusk , full sun,…. .
My preferrence i also exposure first than iso to be honest. Certainly when i try to make astro-timelapse where my exposures are going above the 30s. because i’m afraid my images get to blurry otherwise. i’m even go most of the time not higher than 800-1600. but this has more to do with the lightpollution where i live than thinking about the noise 🙂
