Ok guys/gals, i'm going to be taking some rolling shots today, but i want the wheels to look motion blured and not frozen in still. so I was wondering how would I go about doing this. I have a rebel xti, i'm pretty sure it has to do with the ISO speed but i'm still learning, so any help would be great!

Shutter speed is the important aspect here, ISO kind of plays into that, but so does aperture. Anyway, I'd set the camera to Tv (I think that's the mode) and IIRC 1/60 should give you wheel spin, however you may need to pan with the car, or else the car will have blur. By panning the car will remain in focus, while the background will be a little blurred.

Hope that helps.

 

like on a magazine cover? its the shutter speed. i've done these shots and we use a rig. they're about 250 bucks from b&h

 

thanks

 

TV would work fine for you at 1/50 1/60 or something around there. Or you can shoot M. Set your aperture using the light meter. If it's extreme up the ISO. Shoot RAW if you can.

 

Its all shutter speed.

There are 2 ways to do it really, you can either pan with the car to help intensify the effect or you can drive in a chase car and just snap the picture (let the fact that you are both going ~40mph make the blur rather then camera itself).

Don't be discourged either. When I took my great pan shot, I probably deleted ~100 photos as only one came out the way I wanted it to:

 

isn't that always the case?

 

Start with TV mode. Depending on the vehicle speed, set your camera to ~ 1/60, as mentioned and ISO at 100.

Depending on the available lighting, the camera will determine your aperture. Let's say it's f/5.6. If you want more depth of field, increase your iso to 200 and the aperture should increase to around f/8.0

You'll eventually learn how to manipulate your ISO to get the aperture where you want (when shooting in TV mode).

 

I've heard somewhere people do 1/MPH as their shutter speed. Just a FYI..I dunno how well that works, but I imagine at 20-30-40mph rolls, it should be fine.
