Hey guys so this week is rolling shots and me and my girlfriend went out trying to figure out how to do it but it wasnt working out so well. We got a cannon t3i. Anyone have any suggested settings that work well and how we can adjust to get better shots. Thanks guys
okay, so right off the bad, you should be shooting in shutter speed priority OR manual mode.... to make it easier since you're new at rolling shots, I would just go with shutter speed priority.
There's an old rule of thumb about shutter speed that goes back to the old film days... Your shutter speed should be at least your focal length (and that is ideal for all situations, not just for rolling shots). So, in other words, if you're shooting at 35mm, your shutter speed should be AT LEAST 1/35th or faster, no slower. However, again... this is a rule of thumb that goes back BEFORE the digital age, so since you're shooting a APS-C body (non-full frame), I'm not sure if the rule applies the same or you have to factor in the crop, in your case 1.6. If so, then it would be closer to 1/50th. If you have a lens that's got image stabilization, then that gives you 2-4 stops advantage. But for the sake of it, let's just go with the old rule of thumb and go from there.
So, assuming that you have the kit lens, which is 18-55mm (right?). If so, it's actually fine for rolling shots, I would choose a focal length, and IMO 18mm is a good angle (but you in the chase car might have to be pretty close). btw, I'm sure you already know, you're going to need 2 cars and 3 people... The subject car, and the chase car... 2 drivers and the camera person.
Going by the rule of thumb, @18mm, the slowest shutter speed you'd want to go (and no slower) would be @1/18th speed but since I don't believe there's a 1/18th shutter speed, just go with 1/20th. Why slow shutter speed? Because you're trying to blur the background and the foreground (the road). And as long as you (in the chase car) are going the same speed as the subject car, technically, the subject car is staying the the same spot in the frame of your camera. 1/20th might be a little tricky so if the shots are coming out blurry (on the car), then perhaps speed up the shutter a bit.
@very slow shutter speed, remember, you're going to be "letting in" a lot of light, so which means your camera is going to automatically stop down the aperture, otherwise you'll be over exposed. I would just set the ISO @100 or whatever is the lowest (I believe with your camera, it's either ISO100 or ISO200). If your pictures are coming out overexposed, then raise the shutter speed a little. Both cars do NOT need to be driving super fast for this effect. I would NOT do this kind of shot at high noon because there will be too much light (unless it's over cast of course). Or if your subject car isn't coming out sharp, then the shutter speed is too slow and you may need to raise the shutter speed too... So, having steady hands WILL help.

this rolling shot is pretty cool, but see how @1/50th of second on a 50mm focal length, from that angle, the background isn't really "that" blurred (but the road/lane is)

this photo (link below of the VW Jetta) won't embed but see how @1/20th the background is more blurred? The distance of the objects in the background matters also. Where as the photo of the vintage Corvette above, the buildings are far away there for those objects will NOT appear to be as blurred even if the shutter speed is slower

That said, which leads to something else rather important, how far of the background objects are away DOES matter, the closer they are, the more of the blurred effects you're going to get. And also the angle where you're positioning yourself matters too.
Here's a shot of the subject completely from the side... it's @1/50th and on a 20mm focal length, so the shutter speed in the case didn't have to be as low, but yet, the blurred effect is more pronounced from this angle

another pretty good example 1/25th shutter speed, on a 17mm focal length (but this is a full frame camera)

anyways, you get the point...
oh and I highly recommend using a camera strap!
