Canon Ixus Troubleshooting

As increasing the shutter speed of fire, the slight tremor or movement of the camera begins to become visible as a blurred image.

A rule of thumb is to not go below 1 / focal length (35mm equivalent) for the shutter speed. For example, when taken with a goal of 30mm, you should not have a shutter speed below 1/30s. However, if your focal length of 200mm, then the shutter speed minimum would be 1 / 200, much faster because the focal length is longer. Several times I found in practice that can take a very slow one off easily 2 points and often slow if you have a steady hand and good handholding technique.

How the Image Stabilization:
Image stabilization compensates for the passage of the vibration sensor or the lens to compensate for camera shake. This means you can shoot at shutter speeds slower without blurring effects of camera shake. This is very useful in a variety of situations. For low light, if you use more open and high sensitivity ISO, image stabilization can not afford to take a lower ISO for better image quality. Or, if you have a long lens, where the shutter speed needed to produce clear images they are very fast, image stabilization can extend the range of shutter speeds can be used for 2-3 stops.

There are two main problems to know about:

Firstly, it is not magic does not replace a tripod.

Image Stabilization extends slightly speed range that can be used. In other words, simply because the camera has image stabilization, can not wait to shoot with a shutter speed of 1 second for the night and wait sharp images that will not happen. But you can probably get the 1 / 15 instead of 1 / 60 seconds and get more light. You can get reasonable results 1s bills only if you have a very strong hand and put a kind of support (not necessarily a tripod).

Secondly, it does not stop not subject movement.

If you're shooting a scene again, this is not important. Stabilization work on the image to ensure that the image is sharp and will be. But if you shoot a scene with motion, the following problem arises: the image stabilization, usually selecting a slow shutter speed to get enough light for good exposure, but you may find yourself with a shutter speed is too low to freeze the movement. Then you get the double image of moving objects in the image. Although generally not desired, can be used to create a "ghost town" type of effect, the attempt to draw a busy street at night with a shutter speed slow. Ultimately, if you need more light and allow the movement of the object at the same time, you need a fast lens, stabilization Image not help.

In the image on the bottom is the limit used in terms of sharpness and the camera, but people on foot and the trams are blurred because the shutter speed low. If you want to freeze the movement here, you may need higher ISO settings, ie, faster or objective image stabilization will not help you here.

Do not be fooled by advertising:
There are different types of stabilization Image on the market today. It is the stabilization of the sensor shift, which is most common in compact cameras. After stabilization of the target appears that is popular in digital SLR and is generally considered more effective, especially when the focal length. Both are good, and you can find one or the other depending on the brand of camera or lens.

There are also some camera makers who say that the high ISO settings are a kind of "image stabilization?" which is just … not true. Be careful with the stabilization of the Digital Image "or similar terms when you are looking for a camera. The plane is very likely that no stabilization occur, hence the digital. "

Do you need image stabilization in the camera or lens next?
Well, if you shoot in low light or at longer focal lengths, is a very useful feature to have. Although not a replacement a tripod or a faster lens is still very useful. I must admit I am very familiar with image stabilization and now the challenge using a non-stabilized camera in low light. No must have a function, but if you can get it for a reasonable price, go, I bet you will find useful. It simply makes it easier to get good pictures in low light.
