Frequently asked questions
- How do I fix a photo that is too dark?
- Increase the brightness and exposure sliders. If the highlights blow out, bring down the contrast slightly. The live preview shows your changes in real time so you can fine-tune.
- What is the difference between saturation and vibrance?
- Saturation increases the intensity of all colors equally. Vibrance boosts muted colors more than already-saturated ones, making it better for photos with skin tones (it avoids making faces look orange).
- Can I apply the same color adjustments to multiple images?
- Yes. Set your adjustments on one image, then batch process the rest of your files. All images will receive the same corrections, ensuring visual consistency across a set.
