Question: How do you get rid of motion blur, if you don't intend it to be an artistic effect. Do you use shorter exposure times?

And if so, does the exposure time have to be proportionally shorter for faster moving objects, i.e. does a car traveling past at 65 mph require a much shorter exposure time than a skater?

What are some of the rules of thumb here?

You're very welcome.. technically though, you need a larger aperture setting to allow as much light as required and very fast shutter speed.. but my earlier rule of thumb tends to work really well :)

Sougata, you answered yourself. And Balajee, welcome and thanks for responding. Yes, bigger aperture and shorter exposure times.

If its too bright and you cannot get a fast enough shutter speed even with the maximum aperture, you need to use a neutral density filter (a filter that abosrbs some light).

For any photograph, the amount of light you need to expose your film/CCD is fixed. And this is a product of your exposure time and the aperture diameter, right? So the faster you shoot, the more you need to open up your aperture to let the correct amount of light in.
