White screen for your negatives
Turn your screen brightness up manually. Hold the negative a short distance away from the screen, so its pixels stay out of focus.
Tap anywhere or press Esc to exit.
A couple of tips
Turn off night mode or warm screen filters. Keep the negative parallel to the screen and avoid reflections. If full screen is unavailable, the white page still works.
If your screen dims or locks, adjust your device’s automatic lock setting.
