This is a pixel pushing program, not a photo retouching program. You should look at Photoshop or GIMP if you need red eye reduction. Or just learn how to use the flash. The user’s manual, keyboard shortcuts list 和 screenshots are available from Arahne’s web site https://arahne.org
With ArahPaint, easy things remain easy, while complicated ones remain impossible 😉
