To avoid red eyes in your photographs, make sure that your camera either has built in red eye reduction or you change the direction of your flash. If you did shoot a photo and it contains red eyes, you can easily remove them through the use of a graphics software such as Corel or Photoshop.
Use speed when capturing your pictures. If you take too long, the subject could move, the sun could move behind a cloud or it could start raining. Anything could happen, so don't delay. A camera which allows you to make quick photos will give you the best results.
Very Creative photography.
