How to Avoid Camera Shake
From your Photography Guide

Camera shake is the main cause of unsharp pictures. Take simple steps to avoid it.

Difficulty Level: Easy    Time Required: 5 minutes

Here's How:

1. Almost every picture will be sharper if you use a tripod. However if this isn't possible follow these simple rules.
2. If you can control shutter speeds on your camera, always set one which is 1/60 second or faster.
3. With telephoto lenses you need to use faster speeds as they magnify the subject (and any movements you make.)
4. If you have a lens with focal length around 100mm, use 1/125 or shorter unless you use a tripod.
5. If your lens is around 200mm, use 1/250 or shorter - or a tripod.
6. For other focal lengths, rely on the rule that you should use speeds faster than 1/focal length.
7. Stand still, legs slightly apart to take your pictures
8. If possible, lean against something firm to steady yourself. Supporting the lens on anything solid is a great idea - though make sure you don't pick up vibrations.
9. Hold your elbows in firmly against your chest.
10. Hold your camera firmly against your forehead.
11. Take a breath, not too deep, and then hold it until you have taken the picture.
12. Squeeze the release smoothly - don't stab at it.

Tips:

1. You will be able to use faster shutter speeds if you open the lens aperture more. Consider using monopod, miniature tripod and other similar devices.
2. 400ASA film is fine for most subjects unless you want very large prints. Use faster film for poor light.
3. It is possible to use slower speeds than 1/60 with wideangle lenses, but you are very likely to get subject movement with living subjects.
