to add a color filter, if desired. Swipe vertically on the image to adjust Brightness, Contrast, and Grain. Once selected, swipe horizontally to enhance:
- Brightness Darken or lighten the image.
- Contrast Increase or decrease the overall contrast in the image.
- Grain Add natural-looking grain to the image. A value of 0 will ensure no grain is added.
