Shutter settings

[beachmom]

Is a 1/125 shutter speed fast enough for a bride walking down the isle or should I up it to 1/250?

What are the rest of your settings? If you can use 1/250 without going over ISO800 (assuming you're using an SLR), then I'd say go ahead and do it. Are you using flash?

It depends on many factors, namely:
how is the ambient light?
what focal length are you using?
what ISO?
are you using flash?
what aperture are you using?

But here's a general rule:
The faster the better without underexposing your shot

1/125 can be iffy, especially if you have low lighting. Try looking up some wedding photo tips.

You can always practice with the help of a friend, or just shoot yourself with the self-timer. The thing is, the light you get when you get there is what this is all about. You can't plan your shutter speed settings in advance without a lot of knowledge about the future.

When you get there, set your ISO as low as it goes, and in P mode, check what recommended shutter speeds you are getting. In P mode you can alter the balance between aperture size and shutter speed, so you have some room to decide, assuming in this circumstance you have a nice fast prime on, on taking a picture with lots of bokeh, or including the people in the background in the shot.

Remember that your shutter speed should be at least the reciprocal of your focal length. That is, with a 50mm, you need at least 1/50th of a second shutter speed or you have no hope of holding the camera still enough without a tripod. If you are at your widest aperture and you need a faster shutter speed, the ISO should be moved up, of course, but I would like to say that it might be better to have a sharper image with a bit more ISO noise than it would be to have any motion blur.

i agree with grimm
noise can be reduced but blur image cannot be unblurred
