Default Need help with action

I need to capture the foot timing of my dogs. I've read the user guide, it does not give examples of proper shutter speed, ISO, aperture settings for different types of action and I have little time to figure it out from scratch as I'll need the photos soon. Much thanks!

Sounds to me like you need a video camera, not a still camera. The precursor to video was invented for something very similar to this (to prove a bet that a horse had all its feet off the ground while trotting, I believe.)

People should correct me where I'm wrong. I'm speaking from some practical experience and a fair amout of learned knowledge (which could be wrong.)

If you really want to use a still camera.... you are going to need to stop the action, so that means a high shutter speed. To achieve this you'll need lots of light or a high ISO setting. This is because the faster the shutter, the less light will be used for the picture. Therefor you'll need a bright setting to make up for that. A higher ISO will make the camera more sensitive to light (basically) but there will be more "noise" in the picture (lower quality)... but you don't specify how important picture quality is. And some cheaper digital cameras don't have much flexability with ISO.

Depth of field and amount of light will effect what aperture you'll want. I haven't played much with DOF, so I can only comment on what I've read. A larger aperture will give you a smaller DOF, a smaller one gives a larger DOF. It will probably be easier to shoot with a larger DOF to guarentee that the dog is within the focus plane. But a smaller aperture will drop available light... so again, you'll want as much light as reasonably possible to make your life easier.

I hope that helps. In the end, you're shooting digital so take lots of pictures. Try out different settings and see how it comes out. That will be better than almost any detailed guidance someone gives in a fourm.

ps. The purple font you chose to post your message in is rather hard to read. If you really don't want to use white, I'd recommend yellow. It also stands out quite well.

I forgot to add what camera I'm using, it's a Canon G3. I've actually used a disposable camera, in a pinch, to catch the timing and it worked, certainly the G3 can handle this.

When taking action photos you need to learn tracking. You also need to press the shutter button half way so that it will auto focus before you depress the button fully. This will prevent shutter lag. I practiced tracking by shooting cars as they come towards me. You have to creat an angel between you and the target. If you try to shoot head on you will end up with blurred pictures. Go to www.shortcourses.com and you can read one of the tutorials on digital cameras.
