I have a 300D and I am new to all of this. Today, I would like to take some shots of my pup running in action and I have no idea how fast I should do the shutter speed to get a correct exposure or what setting I should have my camera outside. Almost every picture I have taken with my dogs with this camera have been blurry so today I want to challenge myself in getting the correct exposure with no blurriness.

What should I do?

Try setting your camera in aperture priority...all the way open (if it's the kit lens, I belive that would be somewhere between f/3.5 and f/4.5 depending on your zoom)... Take a reading off the grass near where he is going to be, and see what the shutter speed is...you'll want at least 1/400 of a second or so to really freeze action. If it's faster, you can use a smaller aperture to get more depth of field. If it's slower, raise the ISO to 400 and see what shutter speed it gives you then...that's what I do, use aperture priority, and adjust ISO accordingly. Good luck.

It depends at what angle the dog is running in relation to your point of view. For example a bicycle going horizonally past you will need a faster shutter speed than one coming stright at you.

A safe bet would be to put the camera on aperature priority (I think its called AV on canons) and open your aperature all the way up. This will insure you are using the fastest shutter speed for any given exposure. If that is not fast enough bump up your ISO.

Oh...I forgot about AI servo on the rebel...you might be forced to shoot in Sports mode, because if your dog is running fast, and your DOF is low, no matter what in normal focus mode, your dog might be out of focus by the time you snap!

I think you are in good hands here! Good luck and be sure to post :P

Another way to try it is to put your camera on TV (shutter priority) then set it to about 1/200 sec, the aperture will set automatically.
You won't have to worry about getting blurred images that way.

The only problem with that is one will run out of f-stops much quicker than shutter speeds.

about the camera setting..

ISO: 800. ( i think 1600 is too much grain..)
Camera mode: AV
Apereture: 3.5
now the camera will automatic select the best shutter speed. and in bright day light WITH ISO 800 it will select really fast one.

now about the shooting:

1st folow the dog while running and make, half press focus and shoot..
now.. continue your motion with the camera even after you half pressed and pressed all the way... the result will be a sharp dog (or object)
and background will be blured with motion.. i like this way the best..

if everything is sharp then its what you asked for isnt it..

but if you play with the apereture and make it higher and coz the pic to more exposed by time.. (depend on the speed of the dog as well)
then you can have the result of a dog sharp and motion blur bacground..
something like this:
' . substr('//images.dpchallenge.com/images_portfolio/41277/thumb/214022.jpg', strrpos('//images.dpchallenge.com/images_portfolio/41277/thumb/214022.jpg', '/') + 1) . '
although its ps one.. but thats what i mean.

you can see another example in my "Animals" folder of the kea bird:
' . substr('//images.dpchallenge.com/images_portfolio/41277/thumb/211365.jpg', strrpos('//images.dpchallenge.com/images_portfolio/41277/thumb/211365.jpg', '/') + 1) . '

see the setting:
Aperture: 5.6 (coz i zoomed)
ISO: 800
Shutter: 1/400

in this case the wings are motion because it probebly moved so fast or i fucked it up bye moving too fast according to the bird..
hope i helped..

you can do it many ways.. its all about the setting

p.s.. putting just Tv as 1/2000 is good only in optimal light for the shot.. (the pic might be underexposed) and i think its better if you learn your all optional camera setting...

How are these? I actually got it with out them blurring. They aren't the best composition wise etc but at least I got it. I know when I bring her to the Dog Park I will bring my camera and try some better scene shots.

Great start Ali! I like the 2nd shot the best, though the highlights on the ball are blown, cos the focus is more on Maggie (building in the background is out of focus).

edited to ask....what settings did you use for these shots?
