CHEELA PLAINS TECHNIQUE SERIES | 1. SINGLE EXPOSURE
We’re starting with the foundation of astrophotography: the single exposure.
One shot. No stacking. No fancy techniques. Just you, your camera and the night sky.
The goal is to capture enough light to reveal the stars and Milky Way without making the exposure so long that the stars start trailing.
You’re balancing:
- Shutter speed: long enough to capture light, short enough to keep stars sharp.
- ISO: high enough to reveal the sky, without introducing unnecessary noise.
- Aperture: wide enough to gather light, while watching for stretched stars and lens distortion.
And don’t forget your foreground. A wide aperture means a narrow depth of field, so focusing becomes critical.
I teach the theory behind all of this, so you understand why you’re choosing your settings, not just memorising them.
Master the single exposure and you have the foundation for everything that comes next.
This image is from Lake Campion sometime around 2018 - I never shoot single exposures anymore so needed to head back in time to find an example. Whilst I cannot remember the exact settings I used I am guessing around 15 seconds, f2.8 ISO 4000.
