Shoot for the moon. OK, that's a tired old cliche. However, as we continue to stay confined in many ways, night-time photography can be interesting to almost any photographer. And, I often hear a wide range of questions on how to proceed.
Let's just talk a bit about the easiest object to locate in the night (or evening, or early morning) sky; The Moon.
First, the question of time or Shutter Speed. A tripod is necessary to get tack-sharp images however, you can capture fully acceptable moon photos while hand-held and using whatever form of image stabilization your camera has, If I am shooting hand-held, I usually start with a shutter speed of 1/320 or 1/640 of a second. With a tripod, you can slow this down 1 or 2 stops but NO slower. The moon IS moving rapidly.
With this as a starting point for your exposure triangle, an ISO of 200 to 500 should be in the right rnage, and an aperture in the midranges. I like to keep the aperture small enough to ensure a good depth of field. (With the Olympus eM1-III, the ability to show the focus range in the viewfinder is an excellent feature.) Within this "middle aperture" range, I adjust the opening to find my best exposure. For the moon on a bright night, I'll usually end up 1/3 to 2/3 below what the camera finds as ideal.
Focus is still critical so I recommend a couple shots with your focus set at different points on the moon itself. Generally, the autofocus works well, keep it set to a single point mode.
White balance is always a question. Auto or Sunlight settings produce excellent results. I also take a few shots with the Image mode set to MONOCHROME to see (from the camera's JPG view) how the photograph will look if I convert the final choice to a black & white output.
Have fun, don't stay up TOO late.
