    I have the same problem. Before taking the picture, the image in the view screen looks fine. After I push the shutter button, the flash goes off and the picture is taken. All of the pictures come out very dark.

    I have tried adjusting the exposure settings on some of the manual modes, and it helps a little, but it doesn't completely solve the problem. Furthermore, the exposure cannot be adjusted in the auto mode.

I sent my camera into Canon for repair. They said the flash was malfunctioning, and there was something wrong with the flash exposure control. The repair cost about $87. It took approximately 10 days from the time I sent the camera in until the time I got it back.

I just got my A640 back from Canon's repair center. Same problem as everyone...dark pics in Auto mode with flash. Program and other manual / Tv / Av modes works ok. With shipping it cost me $93, took about 10 days, but they fixed the flash, replaced the outer shell/ top covers, cleaned it up, and made it look new. My photos in Auto now look fine when using the flash. I was considering a new G10 for Christmas, but they replaced the outer shells (which was the dark grey) with spiffy Black. It's looks cooler now, so perhaps I'll keep it for a while.

My photos are coming out dark on my Nikon D5100...should I be using an additional flash? An extra one attached to the camera? Sometimes they look dark on the live view and come out okay after the picture...

The build in flash, will be useful within several meters (15 to 20 feet) if it is really dark.
Your camera should be capable of taking pictures in poor light conditions. Try to shoot in automatic mode. The mode dail to AUTO. (green camera symbol). Then view the picture with info. There you can see the ISO, Aperture and shutter time. From there you can experiment for darker or lighter pictures. For this you can choose M, A,S or P.
In each of these modes, you can use the following steps.
On top of the camera, close to the shutter release button you see a little knob with a +/- sign. If you press that button, you should see a 0.
If you see a - figure, this means the picture you shoot all be darker than normal. If you see a + sign with a figure it means the picture will be brighter. While pressing that button and turning the command dail, you can choose -3 to +3 EV. That is much darker and much brighter.
If you shoot many pictures in bad light conditions, you could buy an external flash. A Nikon flash will work very good and automatic, with your camera, because camera and flash will communicate and help each other to make better pictures. Cheaper external flashes can work too, but most of the time you must change settings manual on the flash. Never use old flashes, that were build for analog cameras. They sometimes switch with a voltage higher than your camera can handle. The camera can be damaged by such a flash.

Hi, Suddenly all my pictures are getting too much light. In the house, the photo is more or less ok, but not super. Outside I just get a white flash on the screen

Check the ISO should be on AUTO or a lower number. Check the "exposure compensation" should be at "0" can set it lower for darker pictures.

I take photos with the color pix s210 outside with natural light and the photos come out good, but when I am inside using artificial light the photos come out fuzzy. Is there a setting I can use to correct...

in darker settings your chip will imitate a slower film speed.  The aperture will remain open longer (than it would in bright light) to allow enough light in to the light sensitive chip.  Small movements of your subjects would show as fuzziness.  If you change your setting to sports or action setting the speed will be faster and there will be no blurring.  Then you will have a light issue so use a flash.

I have take photos outdoors and theyre too dark to see.

There is a firmware upgrade to fix the brightness of the captured images when “EVF/LCD mode” is set to “60fps” is darker than that set to “30f/s”.
Please go to the web link here: and sign Firmware Upgrade User License Agreement .

Indoor photos are too dark and skin tones orange-ish

I have the same problem at my church with the indoor lighting on my camera. I'm able to get it work by putting the whole thing on manual and adjusting the lighting settings that way.

Darkening images

When the flash is activated the camera reduces its light sensitivity[In old photo terms it 'Stops Down'] to prevent 'burnout'[or over exposure] As the flash is small powered and has only a limited 'throw' only the objects illuminated by the flash will be correctly exposed. On the other hand- with no flash the camera will open the aperture wider to maximise the light available.
