Problem with underexposed pictures

There are so many causes, why a camera can over or underexpose. If you put the main dial on the camera logo or on the camera logo with the P next to is, every picture should be correct. Only when you have chosen for scene and the wrong scene is selected, you fool the camera.
If the main dial was not on one of the two logo's put it there and test.
Later look in the manual to see how you could improve a picture to your wish, if you want to shoot a fast moving object of a portrait.

make sure that you have not set it to a underexposure in the settings. Pentax cameras can be set to over or under expose any picture by up to 5.0 EV steps

It all depends on the environment you're shooting in. When shooting a wedding reception for instance inside in the evening I will generally use ISO 800 and I quite often use FE Lock which is very handy. FE Lock will pre-flash the speedlite and meter the result based on the center focus point in your viewfinder (it doesn't matter if you have set another focus point it will always meter to the center one so make sure that is over your subject when you use it). To use FE Lock press the button near your thumb that has the * symbol with the center focus point over the subject. You can then re-frame the shot if required and take the picture. The camera will take the picture based on that flash setting and you should find that the shot is better exposed.

CCD FAILURE !

Call Canon for FREE REPAIRS it is a known issue ask them about BAD CCD see this link for service advisory

RATE ME WELL !

If the pictures show up normal on the computer then the back light for the LCD is going bad.

Black pictures mean under exposed or un- exposed film

Underexposed film can mean incorrectly set up or metering failure
Un exposed film simply means the shutter has failed
Open camera and look through the back and operated the shutter
Does it work?

Hey xplaur,
To take a multiexposure photograph you should first expose the film, and then push the multiexposure button which is on the front of the camera on the top left when you are looking at the front of the camera. After you press this button advance the winding lever to set the shutter, and since the multiexposure button was pressed this shouldn't wind the film to the next frame. Now take your second exposure, and if you want to make another exposure on the same frame repeat the process. Keep in mind that every time you expose a single frame after the initial exposure you will be doubling the exposure on the frame. I usually under expose each exposure by one third on a double exposed frame. If you do more than two exposures I would underexpose each exposure by even more. Multi exposures are fun but tricky, and I would suggest you experiment and have fun with it. I will also say that black and white film is much more controllable and forgiving when it comes to this than color film. I hope this helps!

Sincerely,
Allan

it can be possible to select reset icon by selecting menu option.  
it is not possible to take this type of pictures because at auto flash mode the subject can't be covered witin flash range .therefore picture may underexposed however the forground within flash range may correctly exposed.If we do all this at flash off mode the motion of subject will appear  as blurred due to slow shutter speed.

Ok this is a crappy fix but it works for me.

If your flash isn't syncing correctly make sure your on auto flash. when your flash flips up and you get the beep push the piece that holds the flash just a little forward. and walla your flash syncs up.

When you are photographing scenes with mostly light objects (for example, snow, water, and sand), the picture is usually underexposed (darker than it really is). The camera meter registers the brightness of the scene and tries to set the camera lens and aperture for an exposure based on average brightness levels (18% reflectance) causing it to underexpose, as in the following picture. When you are photographing scenes with mostly dark objects (for example, shade, shadow, and overcast skies), and very few light objects, the camera may overexpose the image, causing it to be too light. If you have a flash on your camera, you can compensate by adding "fill flash" for some extra light. If your camera has an exposure compensation adjustment, you can increase or decrease the exposure to correct for these exposure problems. Increase the number to make the image lighter, and decrease the number to make the image darker. You may want to try a series of shots with different exposure compensation adjustments to get a feel for how much difference these adjustments make.
