Rule: The shutter speed should not be lower than the number on the lens.
For example, this picture was taken at shutter speed of 1/15s and lens 20mm. The shutter speed 1/15 is less than the lens number 20mm = blurry!
|f/5.6, 1/15, ISO 3200|
Here are more examples of what happens when I didn't follow the rule:
Lens at 40mm, shutter speed 1/6s...what was I thinking?
|f/5.3, 1/6, ISO 1600|
Delicious blurry cornmeal pancake
Lens 26mm and shutter speed 1/13s
|f/6.3, 1/13, ISO 1600|
This would have been a good strawberry shortcake...except at 42mm lens and 1/30s shutter speed.
|f/5.3, 1/30s, ISO 1600|
In Miz Booshay's post on focus, she mentioned 9 other tips on achieving sharpness and I thought this rule was the easiest to keep in mind (and steady hand) without messing with a tripod or trying to understand how lens work. Anyways, hopefully I will be able to remember checking my shutter speed before snapping or else I will be posting more blurry pictures.
