FITS Contrast
How to Adjust FITS Image Contrast?
1. Add Your FITS Files
Open reaConverter and drag in one or more .fits files — commonly used in astronomy, scientific research, or thermal imaging.
2. Choose the Contrast Level
Go to Loading settings, select the FITS Contrast section, and choose one of the two options:
- More Contrast — highlights details and enhances brightness for better visibility of faint stars or structures.
- Less Contrast — softens brightness, reducing glare in high-dynamic-range images.
