Pushing the Canon 5D Mark IV and the 6D Mark II to their Low Light Limits
With almost twenty years of experience under his belt, Phil Hart is a world-renowned photographer that specializes in capturing the wonders of the night sky. Earlier this year he braved the frontiers of Northern Canada and captured the Aurora Borealis. With just the Canon 5D Mark IV and the 6D Mark II, these two cameras were pushed to their absolute limit in the freezing cold.
When using the 5D Mark IV, the video was shot at max ISO of 32,000. Although the 1080p footage were a little noisy at first, it was quickly cleared up with the help of Adobe After Effects. Coupled with the deliciously wide Canon and Sigma ART lenses, the untouched files were still extremely usable given the sensors that were used.
The Canon 6D Mark II was also used to capture the auroras in 4K. With a tiny touch up on brightness and contrast in Adobe Premiere Pro, the footage looked like it was shot in a much higher end camera.
Since the aurora only lasted for a couple minutes, you need to be fully prepared even before shooting. Not only was the high ISO compensated with the noise reduction plugin: Neat, you also have to make sure that you
To gain similar results with pictures you could follow these steps:
1. Make sure you are in a dark environment; the darker the better
2. Get yourself a tripod, wide aperture lens and a remote trigger
3. Shoot at long exposures a low ISO or high ISO with low exposure. (Be warned: Higher ISOs
generally mean nosier pics)
4. Tune noise and colours in Adobe Photoshop
