Motion pictures and how?

Anyways, I took this picture with my Canon T1i SLR and 15-55 MM lens. I am not sure if I was shooting in a sports mode or what, but the cars and their wheels are in motion. It's quite comlicated to get this shot often..... What I need to do to get a picture of car where its wheels would be in motion? Any clue? Thanks

Here is a pic sample;

my best guess: slower shutter speed

Do you mean setting a lower ISO speed? I am still a rockie big time.

I'm no expert but the basics are:

Shutter speed controls how long the shutter is open letting light through to expose the image. The longer a shutter is open, the more likely the subject of the picture (or the camera itself) is likely to move, causing a blurred image.

Aperture which controls how much light gets in while the shutter is open for a specified period. If the aperture is open wider, you don't need the shutter to be open as long to get enough light to expose the image, and therefore don't risk the blurred image. If aperture is more closed, you need a longer shutter speed to expose the image - which can cause the blur mentioned above.

ISO is how long it takes for an image to expose the film given a fixed amount of light. A higher ISO film will expose faster so is used when fast action or low light is required. Higher ISO also usually results in image quality degradation and shows up as "grainy".

Shutter and Aperture are the two main things to use, with ISO becoming more important in poorly lit or very high speed situations.

You use the two together to create effects. Play with setting your camera at a fixed low shutter speed and then taking shots with varying apeture settings. Then do the same with a fixed apeture setting but varying shutter speeds. You'll see what I mean.

I don't know specifically how to achieve the shot you want, but I'm sure you can google it. I'm guessing it requires that you follow the car with the camera so the car isn't moving relative to the camera, but the wheels are still spinning quickly, causing the blur on that part of the image.

Again - I'm no expert at all and I may be completely off base on this...

I am referring to the first two images. Thanks


TallTorontoguy, thanks for clearing that up.

the first shot has more work than you think it is...
this is the original


2nd shot...
you just need another car going side by side with exact same speed if possible to avoid any blur. Also, you need to use a little slower shutter speed in order to have the motion background and spinning rims.
