Tips to Avoid General Fault in Photography - In practice we usually see the results of our photos we did not expect, such as blurred images, photo speckled dark, or perhaps the subjects of our photos with red eyes. This post will provide information on how to avoid the common mistakes encountered in photography that produces images that we did not expect.
Reducing Shocks in Camera
Camera shake is caused by a combination of hand movements photographer or inability to keep the camera in a stationary or fixed condition, shutter speed and focus lens (focal length) long so that it will produce images that are blurry or out of focus. The focal length of the lens when combined with a slow shutter speed will create a situation in which the shutter speed is too slow to freeze the image.
Camera shake can be prevented by using a tripod, hold the camera with the right position or raise the shutter speed to a value greater than the focal length (focal length). For example, if the same focal length to 100mm so its shutter speed should be set to 1/100 sec or faster.
Note: Some lenses have image stabilizing features (eg IS Image Stabilizer on Canon lenses), which allows the photographer to take pictures with the shutter speed value is smaller than the focal length of the lens.
Eliminate the Red-eye Effect
Red-eye effect caused by the reflection of the flash directly behind the retina subjects we photograph. Basically, since most of the built-in flash which made ??only one or two inches from the lens, flash sends light that bounces off the back of the human retina, and reflects directly back into the camera lens. Reflections are seen in the image as red, thus creating a red eye effect. Blue-eyed people are very prone to red-eye phenomenon because it has less pigment to absorb light.
There are several ways you can do to minimize or eliminate red eye in pictures:
1. Red eye reduction feature
Some cameras have a red eye reduction feature that forces objects iris shrink before the picture is taken. Almost all digital cameras have this feature. This feature causes the flash to light up twice in two micro bursts. The first little flash to cause your subject's the pupil to contract and shrink, which reduces the amount of retina affected by the flash. When the second flash is triggered, contracted retina produces almost no visible red-eye effect.
The main problem with this method is that it often forcing objects to deliberately turn a blind eye before the picture is taken and not always completely eliminate red eye effect.
2. External flash
External flash hot-shoe mounted on the camera, the direction can be changed in the direction of the ceiling, or even use it without mounting the camera body and steer a little to the right or left of your subject.
3. Post production
If the images have been exposed to the red-eye effect, the photographer also still be able to eliminate it, using computer software such as Photoshop or the other, which will be discussed in upcoming posts.
Reducing Digital Noise
Digital noise is the effect polka dots (spots) on the image for long exposures or high ISO images with the lack of lighting situations.
Digital noise can be reduced by using the ISO setting between 100 and 400. Setting ISO 400 will give you more exposure but ISO 400 reduces digital noise. In anticipation of a long exposure, you need a tripod to freeze the image.
Currently DSLR cameras usually have a noise reduction feature, if its noise reduction is turned on it will automatically be activated when taking pictures with long exposures. The negative side of this feature is the camera takes a significant time-lag between taking pictures. One way to avoid this time-lag is to turn off noise reduction feature on the camera, and use the aperture setting noise reduction after transferring images to the computer.

Pocket camera is designed for daily photograph. It can give you information about photographic situation and kind of picture you need. Each mode of photography apply special setting to the camera.
Several pocket camera settings to maximize your pocket camera:
- Adjust White Balance with available light. Improper white balance will produce tonal colors that do not match and sometimes bizarre.
- Use the appropriate Scene mode. In each pocket cameras usually reserved several scenes to meet your shooting according to lighting situations and motion of an object being photographed.
- Use the Macro mode on an object that is close, without this mode, the object a short distance (less than 50 cm) will blur.
- Make sure the object gets enough light. The role of light is very important because you use low ISO. So get a light as bright as possible, if necessary use a flash or studio mini box.
- If you want to get shallow depth of field (blur background), apply 'spot focus metering' and 'Portrait mode'. The camera will set wide aperture.
- If you want to get deep depth of field (all focused), apply 'Landscape mode', and set 'multi focus metering' the camera will automatically set narrow aperture.
- If you want fast shutter speed, apply 'Sports mode'. The camera assumed that you want to freeze object movement. Its also applied to photograph children activity.
- If you want slow shutter speed, apply 'night mode'. Camera will automatically turn on flash and set high ISO that can make noise to the picture. Turn off flash and set ISO to 100 or 200. You should use tripod or other camera fixation to get sharp and clear pictures, and apply timer to reduce shake effect.
And additional tips is to avoid using digital zoom as it will add noise to your photos.
