A common photography problem: underexposed digital photos

Digital cameras are becoming more and more sophisticated. On one hand they allow high quality automatic point and shoot. On the other hand they allow full manual control of their settings. Regardless of the mode you use there are some scenes that require special care. Without such care your digital photos will be of poor quality regardless of how sophisticated and automatic your camera is.

New digital cameras include sophisticated hardware and software that allow a simple point a shoot usage and result in high quality digital photos. Such high quality digital photos are achieved in most scenarios but in some scenarios solely relying on the cameras automatic feature is not enough. In such scenes the camera hardware and software will make the wrong decision as to the optimal camera setting for the best digital photo. The result will be a poor quality photo.

Being aware of such scenarios can help in avoiding such poor quality digital photos. When you identify such a scenario you can use some simple techniques, by manually setting the camera, by changing the photo shooting angle or by manipulating the scene.

One of the common problems with automatic digital camera photo shooting is digital photos that are underexposed. Underexposed digital photos look dark and lack details. Their color is not rich and the objects tend to look grayish and not ?alive?. The reason for underexposed photos is setting the exposure too low. Although the camera can measure ambient light and make the exposure decisions for you it can be confused by scenes that are more complex. Many times such scenes do not really have one perfect exposure setting and the best exposure depends on the results and the objects in the scene that you care about the most.

For example if there is a very bright light source in the photo it can confuse the camera to believe that there is enough light in the scene for a low exposure setting. The result will be a photo that captures the bright area but darkens all the others. Usually you can assume that scenes that have extreme lighting gaps between different areas confuse the camera ? for example if a quarter of the photo is very bright and the rest is very dark the camera is likely to set the wrong exposure. When you identify such cases you can manually set the exposure to the right value for the results you are looking for. Another options is to pan the camera a bit and point to a scene that does not have such light gaps (for example that does not have a very bright object in it) but that its objects are in the same focus distance as the scene you are planning to shoot. At that point you can press the shutter half way down (or use any other specific camera mechanism) in order to lock the camera focus and exposure settings. Once you have done that you can pan the camera back to the original scene and shoot the photo.

The best way to learn how to avoid underexposed digital photos is by experimenting and practicing. Try to find scenes that will confuse the digital camera into taking underexposed digital photos. Take a few digital photos using the camera automatic mode and review the results confirming the expected poor quality. Now correct the problem and take a few more photos. Review the new digital photos and make sure that indeed the underexposed digital photos problem is gone. Practicing in a controlled environment will help you be prepared to quickly and efficiently handle such scenes in real time photo shooting.

A common photography problem: overexposed digital photos

Digital cameras are becoming more and more sophisticated. On one hand they allow high quality automatic point and shoot. On the other hand they allow full manual control of their settings. Regardless of the mode you use there are some scenes that require special care. Without such care your digital photos will be of poor quality regardless of how sophisticated and automatic your camera is.

One of the common problems with automatic digital camera photo shooting is digital photos that are overexposed. Overexposed digital photos have blown out areas and sometimes are completely saturated and white. Their color is not rich and the objects tend to look white and not ?alive?. The reason for overexposed photos is setting the exposure too low. Although the camera can measure ambient light and make the exposure decisions for you it can be confused by scenes that are more complex. Many times such scenes do not really have one perfect exposure setting and the best exposure depends on the results and the objects in the scene that you care about the most.

A common photography problem: red eyed objects in digital photos

One of the common problems with automatic digital camera photo shooting is digital photos that have objects with red eyes in them. Red eyed objects in digital photos is a very common phenomenon. It is usually common when taking digital photos of people or animals and using a flash in a dark environment. The eyes of objects in such digital photos have some red glow in them. The reason for the redness in their eyes is light that is reflected from the blood rich back of the eye. There are a few things that you can do to prevent red-eyes: some cameras support a ?red eye reduction? mode. In that mode the camera fires the flash a few times before taking the photo. Although this can help reducing red-eye it can also result in photos of people with their eyes closed (as they are blinded by the pre-flash their reflex is to close their eyes). Other ways to prevent red-eye is to use bounce flash (you can do that with special equipment or for example by pointing the flash to a white wall) and using more ambient light if possible (for example by turning on all the lights in the room). Some cameras include built-in image processing software that automatically removes red-eye from the photos or alternatively you can use many software packages on your home computer to accomplish the same.

The best way to learn how to avoid red eyed objects in digital photos is by experimenting and practicing. Try to find scenes that will confuse the digital camera into taking digital photos with red eyed objects. Take a few digital photos using the camera automatic mode and review the results confirming the expected poor quality. Now correct the problem and take a few more photos. Review the new digital photos and make sure that indeed the red eyed objects are in the digital photos. Practicing in a controlled environment will help you be prepared to quickly and efficiently handle such scenes in real time photo shooting.

A common photography problem: dark silhouettes in digital photos

Being aware of such scenarios can help in avoiding such poor quality digital photos. When you identify such a scenario you can use some simple techniques, by manually setting the camera, by changing the photo shooting angle or by manipulating the scene.

One of the common problems with automatic digital camera photo shooting is digital photos that include dark silhouettes in them. Dark Silhouettes appear when you are taking digital photos in a scene with a bright light source behind the object. An example of such a scene is when the sun is behind the object. The result will be a digital photo that includes a dark silhouette of the object. One scene that is very likely to result in such a problem is when taking a photo of someone on the beach against a sunset. The result will be a dark silhouette of the person with a good photo of the sunset in the background. Dark silhouettes are a result of the camera setting the wrong exposure. Because of the bright background the camera sets a low exposure and the object that are not lit from their front are severely underexposed.

The dark silhouettes in the digital photo can be eliminated by simply using the camera?s fill-in flash. When taking a photo with the fill-in flash turned on the flash lights the object making sure that it is captured with all its details. Use a fill-in flash when taking pictures of objects with a bright light source behind them. One limitation of this solution is that the objects must be within the flash effective range ? otherwise the flash is useless and they will still appear as silhouettes in the photo.

The best way to learn how to avoid dark silhouettes in digital photos is by experimenting and practicing. Try to find scenes that will confuse the digital camera into taking dark silhouettes digital photos. Take a few digital photos using the camera automatic mode and review the results confirming the expected poor quality. Now correct the problem and take a few more photos. Review the new digital photos and make sure that indeed the dark silhouettes problem is gone. Practicing in a controlled environment will help you be prepared to quickly and efficiently handle such scenes in real time photo shooting.

A common photography problem: Shaded objects in digital photos

Digital cameras are becoming more and more sophisticated. On one hand they allow high quality automatic point and shoot. On the other hand they allow full manual control of their settings. Regardless of the mode you use there are some scenes that require special care. Without such care your digital photos will be of poor quality regardless of how sophisticated and automatic your camera is.

Being aware of such scenarios can help in avoiding such poor quality digital photos. When you identify such a scenario you can use some simple techniques, by manually setting the camera, by changing the photo shooting angle or by manipulating the scene.

One of the common problems with automatic digital camera photo shooting is shaded objects in digital photos. A good example of shaded objects in digital photos is when taking a portrait photo in daylight. The digital camera ambient light sensor measures enough light to set a relatively low exposure value. But even scenes with that have enough ambient light can result in shades that appear on the object depending on the angle of the light source relative to the object. For example if the object is a person with his face lit from the side the object?s nose can create shades. Another example is if the object is a person that is wearing a hat and is lit from a light source above ? in such a scene the hat can create shades on the object?s face.

The camera can not automatically identify such problems and correct them. One way to easily eliminate the shades on the objects is by using the camera fill-in flash. Turn the fill-in flash on. When taking a photo the fill-in flash will fire and will light the shaded areas on the object. One limitation of this solution is that the objects must be within the fill-in flash effective range. Otherwise the flash light will fail to light the object and the shades will not be lit.

The best way to learn how to avoid Shaded objects in digital photos is by experimenting and practicing. Try to find scenes that will confuse the digital camera into taking digital photos with Shaded objects. Take a few digital photos using the camera automatic mode and review the results confirming the expected poor quality. Now correct the problem and take a few more photos. Review the new digital photos and make sure that indeed the Shaded objects problem is gone. Practicing in a controlled environment will help you be prepared to quickly and efficiently handle such scenes in real time photo shooting.
