Camera not capturing

First click is to show focus and 2nd click is to capture. its common in most camera's. Nothing to worry about.

The S2 IS is a very nice camera, but is known to be susceptible to stuck shutter problems. A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

Self-timer
(10-second delay) it will have a 10 on it


Time to get yourself into the picture. Place camera on a tripod or flat surface.


Self-timer
(2-second delay) it will have a 2 on it

Allows for a steady, auto-shutter release on a tripod.

Self-timer
(2 pictures) it has a 2X on it

Capture 2 shots (one picture taken after 10 seconds and another picture taken 8 seconds later).


First Burst Flash forced off.it has like 2 folders in front of the camera

Camera takes up to 8 pictures (2 per second) while the Shutter button is held. The first 8 are saved. (Capture an expected event e.g., baseball swing)

Last Burst
Flash forced off. it has 2 folders behind the camera

Camera takes up to 30 pictures (2 per second up to 15 seconds) while the Shutter button is held. When the shutter button is released, only the last 8 pictures are saved. (Capture an event when the precise timing is uncertain e.g., a child blowing out birthday candles.)

This is electronic shutter problem that is the reason you get blinder effect/ noise on picture. Electronic shutter is located in lens mechanism and lens assembly will be replaced to solve the issue. Nearest Samsung service center or local camera repair shop will help you to replace lens assembly.
Thanks.

I was having the same problem.. And since I could not afford to take it to the shop, I tried everything I could think of...
Then I fixed it!!
It seems that the slide door behind the shutter was stuck for some reason... If you remove the lens.. (make sure the camera is in manual mode)... snap a shot so the shutter is up.. then gently slide the panel in the back down....
Once I did that.. the camera was working again.... Hope this easy solution works for you guys....

The shutter button features a two-stage action. Pressing Halfway Pressing halfway automatically sets the exposure, focus and white balance.
The indicators light or blink as follows.
Upper Indicator
" Green: Metering complete (two beeps sound)
" Orange: Flash will fire
" Blinking Orange: Camera shake warning / Insufficient exposure
Lower Indicator
" Yellow: Macro Mode / Manual Focus
" Blinking Yellow: Focusing difficulty* (single beep sounds)
* When the indicator blinks yellow, lock the focus before shooting.

The longest part of the shutter delay is caused by the autofocus mechanism. Most cameras will let you press the button half-way down and wait until the autofocus is locked. Then wait for the action to occur. When you press the button the remaining distance, there will be a shutter delay of about 0.2 seconds before the picture is taken. Using that technique will let you capture action shots. There is no way to improve shutter delay on any particular camera. The newer digital cameras are showing improvement in this area. Some are achieving autofocus lock in 0.4 seconds and shutter delay of an additional 0.1 seconds.

The Shooting modes are as follows: PROGRAM (P)/AUTO Modes Used for general photography. The camera automatically makes the settings for natural color balance. In PROGRAM (P) the brightness (exposure compensation) can be adjusted. In AUTO mode you cannot use exposure compensation or panorama features. Portrait Suitable for taking a portrait-style shot of a person. The camera automatically sets the optimal shooting conditions. Sports Suitable for capturing fast moving action without blurring. Even a fast moving object will appear to be stationary. Landscape Suitable for taking photos of landscapes and other outdoor scenes. The camera automatically sets the optimal shooting conditions. Night scene Suitable for shooting pictures in the evening or at night. The camera sets a slower shutter speed than is used in normal shooting. If you take a picture of a street at night in any other mode, the lack of brightness will result in a dark picture with only dots of light showing. In this mode, the true appearance of the street is captured. The camera automatically sets the optimal shooting conditions. If you use the flash, you can take pictures of both the subject and the background. Nightscene + Portrait Suitable for taking photos of your subject in the evening or at night. This setting employs a slow shutter speed, the camera should be stabilized to avoid camera shake resulting in a blurred picture. Landscape + Portrait Suitable for taking photos of both your subject and the landscape. This setting allows for both the foreground subject and background landscape to be in focus. The camera automatically sets the optimal shooting conditions. Self Portrait Enables you to take a picture of yourself while holding the camera. Point the lens towards yourself and the focus will be locked on you. The camera automatically sets the optimal shooting conditions. The zoom is locked to wide-angle and cannot be changed. Indoor Optimum settings for taking pictures of family gatherings and groups of friends. This mode reproduces the background clearly capturing the atmosphere. Beach Suitable for taking photos at the beach under a bright blue sky. Colors of the sky, the beach and people are reproduced vividly. Snow Optimun settings for taking pictures where backgrounds are snow fields. Settings are similar to Beach settings and colors of the sky, the greenery and people are reproduced vividly. Fireworks Optimum settings for capturing fireworks in the night sky. Since this setting employs a slow shutter speed , the camera should be stabilized to avoid camera shake resulting in a blurred picture. Sunset Optimum settings for capturing pictures of the setting sun. This mode reproduces reds and yellows vibrantly. Again, this setting employs a slow shutter speed , the camera should be stabilized to avoid camera shake resulting in a blurred picture.
