6) How can I prevent red-eye in my pictures?
Here are three great tips to help reduce the chances of getting red-eye in your photos:
1. Turn on all the lights in the room before shooting. The additional light will narrow the pupils in your subject's eyes.
2. Have your subject look slightly away from the camera, not directly into the lens.
3. Use a camera with a red-eye reduction feature. This feature emits one or more split-second flashes just before the main flash fires, thereby narrowing the opening of your subject's pupils.
If these tips don't work, purchase a red eye pen, available at most MotoPhoto stores.
If you have yet to see the latest technological genius of photography known as the Advanced Photo System, you may be in for a surprise! And a good one at that! The photo industry has seen incredible growth in Advanced Photo System camera sales and photo imaging which is now a strong part of all photo imaging. So why all the excitement? The new technology offers plenty of advantages over conventional 35mm cameras including the option of choosing (through the view finder) one of three different size of prints. It allows you to pick a format (4x6, 4x7 or 4x10 or 11) which best suits the subject matter.
The Shutter Speed is an indication of how fast or slow does the Shutter mechanism on a lens operates. The faster the shutter speed less light reaches the film through the lens opening. The slower the shutter speed the more light reaches the film through the lens opening. By moving the shutter speed dial by one notch you've made a change of one f-stop. Shooting with very low Shutter Speed requires a very steady camera and the need to mount it on a tripod. Shutter Speeds of 1/60 second or higher usually do not require the use of tripods. Higher Shutter Speeds 1/250 or higher are ideal for action photography (motion & sports). High Shutter speed allows you to freeze the image. Changing the Shutter Speed also allows you to adjust for the ambient light brightness. Normally when faster speed films (ISO 400 or more) on sunny days your Shutter Speed should be higher for better results.

9) What is an f-stop (aperture)?
The aperture is an indication of the size of the opening in the camera lens. This size can be increased to allow more light to go through the lens or decrease to lessen the amount of light going through the lens. To change the lens opening size you change the setting on the f-stop. For example, f/5.6 allows more light through the lens than f/16. Each lens opening increase or decrease increment is called an f-stop. A change in aperture from f/8 to f/5.6 is one f-stop.

Depth of Field is an indication of how sharp are the objects at varying distances from the lens. A small aperture setting will help you keep landscape shots in focus (f/16 or f/22 should yield a sharp landscape shot)) higher film speed allows for better focus for subjects further away from the lens. When the object is to focus only on the subject closest to the camera and to intentionally blur out the background the lens aperture setting should be set for a larger opening (f/2.8 or f/4).
