OverExposed image when using fast shutter-speed

[Fallingslowly]

Hello everyone, I'm needing your help.
When I try to take a photo in daylight with a slow shutter speed, say 0.5 " with a small aprture, I keep getting over exposed photos, which is a big probalm, what setting do I have to put my camera to, to stop it over exposing.
I have a Pentax istDL DSLR

0.5 shutter speed is half a second, which is slow.
What settings are you using?

Get the book "Understanding Exposure" and google for the "exposure triangle".

Look in the manual and read about shutter speeds. .5 seconds in bright light is surely going to give you an over exposed picture.. Not to mention its likely going to be very blurry from camera shake.

Oh sorry my mistake, I ment slow shutter-speed.

If you are trying to slow your shutter speed in the sunlight you are going to overexpose the photo. Try picking up some ND filters.

What is it you're taking a picture of that you would use a speed that slow in daylight? but I agree with NikonME, if you do need a slow shutter speed (for waterfalls and such) you'll have to get some ND filters

Either way..... ½ a second is going to really overexpose an image in bright sun, even if you stop the lens down to f/22, 32 or whatever the minimum aperture is. And at ½ sec., you'll end up with some very blurry photos.

You can't just pick the settings you want, you still have to meter the light. So when you dial in the shutter speed that you want, what is the camera's light meter telling you? It's probably off the scale...so you would need to adjust other settings until the 'needle' come back onto the scale (maybe back to --0--).

If you can't adjust your aperture & ISO to get that, then you've chosen a shutter speed that is too long for the light that you are in. Come back when it's no so bright, or use filters over you lens to reduce the light coming in. (neutral density filters are what is normally used here).

I was trying to capture the movement of barley in a field on a windy day, but a ND filters is probably the best bet for me.

You're getting over exposure because of a slow shutter speed during day light. What's the reason for using a slow shutter speed during day light? I'm just curious.

You have to learn how the camera works to make an exposure.

An exposure is controlled by 3 settings and is known as the exposure triad, or triangle.

Mike mentioned the in-camere light meter. That is what indicates under and over exposure and your camera will have 3 or 4 different metering modes you need to choose from.

Uh...........

I was trying to capture the movement of barley in a field on a windy day,..........

Which begs the question: Why do you think using a fast shutter speed will show movement?

don't use 5"

try something around 1/100-> 1/5 something in that range and you will get what you are looking for.

In sunlight, f22 at iso 100 1/2 a second will severely overexpose... 1/30-1/60th is the slowest in sunlight without a ND filter or a lens capable of very small apertures (like f64), however a filter is better because apertures that small won't take crisp photos.
