Mylio includes an editing tool that quickly identifies if a photo is over or underexposed. These areas of exposure are marked with graphical distortion or red/blue blotches on your photos.
To toggle this on or off, open Mylio and navigate to the Edit section of the Details panel. In the Edit section, locate the histogram. This shows color and dark/light balance throughout the photo.
The histogram includes two dots in each upper corner. The left dot is showing dark parts of the photos (blue), and the right is showing bright spots of the photo (red). Click the small dot to toggle the color on or off.
