If we choose a shutter speed that is too slow, we will end up with blurry, trailed stars. Make it too fast and we won’t capture as much detail as we could otherwise. The trick is to find the correct balance. There are a couple of ways to go about calculating the slowest shutter speed you can get away with. I’ll be covering two of these methods here.
So, let’s quit talking about it and get to it!Read More
