Camera settings help

Quick question, im kinda new to the whole manual camera settings so kinda bear with me.

Im trying out different settings on my digital cam. Im in shutter priority mode. I have the shutter speed set to 1/400. Actually anyting above 1/400 does this too...but my problem is the picture is way to dark. And it automatically sets the apeture to 2.8....I can use the flash and make it lighter, but there are times when the flash is too much light. I would like natural light. Any suggestions?

try using Aperture priority mode instead until you get used to changing the settings - its pretty similar to full auto but with a bit more control and the ability to use RAW too if you choose to.

That occurred because you told the camera to use 1/400. The camera’s largest aperture 2.8 was not large enough to expose the image properly. You could use a higher iso to get the shot or reduce the shutter speed.

Most cameras have an exposure indicator to let you know how close you are to what the camera considers the correct exposure. On some digicams you have to turn that indicator on.

The "&" dudes above are expert. Herewith is just a newbie's hard-learned lesson in case it helps you, too:

The 1/400 means you're giving the camera one 400th of a second to capture the image. It needs to suck in a lot of light to make a pic that fast. The aperture of 2.8 is the widest possible and lets as much light into the camera as possible. But if the light you're shooting in is not bright enough to begin with, the camera still won't get enough in 1/400th of a second to make a good pic.

You can give the camera more time by choosing a slower shutter speed. Go below 1/125, though, and any little movement of the camera (like from pressing the shutter) will play out in your image as blurriness because the camera has time to record the movement as well as your intended subject.

As the shutter speed becomes slower and the camera has more time to drink in light, the 2.8 aperture can let in toooo much light and overexpose your pic. The great thing about digital is you can tell from the LCD image and the histogram whether your first shot's distinctly over- or under-exposed and, if it is, you can delete it, adjust your settings, and try again.

In fact, does your camera's LCD show you the effect of the settings you've chosen BEFORE you click the shutter? A lot of them do and that really cuts down on the frustration.

If I'm having a bad time of it, I retreat to "auto" mode and see what the camera suggests for shutter speed and aperture. Then I go back to "S" or "A" mode and try settings that might be better for the pic I'm attempting than the "auto" suggestion. "Auto" tends to overexpose, so I might want a bit faster shutter speed or a bit smaller aperture to get a better pic than "auto" gives me.

Or maybe I want to use a different aperture because I want a deeper or shallower depth of field for the subject I'm photographing, so I try to match that change with the correspondingly faster or slower shutter speed.

Get good results? Yay, take some more! Not? Rethink, readjust, try again. My judgment over time has been improving.

What is a good shutter speed to stop helicopter blades in motion. I was experimenting with that shot when all this started happening. And also I was trying to shoot a waterfall with quick shutter speed. So if I understand what you all are saying, if it is a nice sunny day out, I should have no problem, but if its cloudy, my pic is going to turn out dark because there is not enough time in 1/400 for light to get in. But if i shoot at lets say ISO 400 instead of 100 i should get a brighter pic, but also with more noise. So im giving up one for another. I'll just have to experiment with it a little bit more and see what results i get. Thanks for the advice.

1/250 will stop helicopter blades most of the time, 1/500 or more is better if you want to freeze the blades.

You are correct with your summary of exposures. Enjoy your experiments, that’s what it’s all about :-)
