Digital Cameras - What you see is not always what you get

For those of us who use a compact digital camera for "normal" purposes, we have experience of setting up our shot, as our items exactly where we want, and then stop, the resulting image appears at the top of the head or arm missing from the scene.

What occurs in these cases it is frustrating phenomenon known as "parallax error. Simply put, it is the result of the camera with one lens through which the camera focuses and records images and additional lens through which a photographer views the scene to be shot. These two views are not identical, and thus the image that results is not always as we imagined it through the viewfinder. This error is most apparent when shooting at close range, as in most of the "portrait" type shots.

Even those of us who are amateurs can avoid the "parallax error" one of several methods.

â € ¢ Use the correct stamps. Many digital cameras provide guidance that can be seen in the viewfinder, the approximate boundaries of the image was taken can not imagine what the lens is actually seeing. The photographer then has to adjust the image as needed. Read the owners manual will reveal whether the camera has this feature.

â € ¢ Use the LCD frame shot. LCD better represents the image, which image-lens to see them. There are limitations, however, with this method. Firstly, the LCD is sometimes difficult to follow in bright, outdoor light, making it difficult to use in such situations. Second, the LCD screen on many digital cameras will be displayed only 85% of what the lens sees, which may result in multiple scenes captured versus less final disadvantage is just the extra energy needed to power the LCD. The electronic viewfinder is another option. EVF, the image captured by the camera and electronically transferred to the screen.

â € ¢ Consider buying a digital camera with TTL mechanism. Parallax error occurs with a TLR (twin lens) camera, but not those with the mechanism of the TTL (through the lens, -). With TTL, the photographer views the scene through the same lens that records the image and is able to picture the scene well. SLR (single lens reflex) cameras use TTL. These cameras are significantly more expensive, bulky and complex than traditional or compact point and shoot type of camera, although an avid amateur extra control that offers photographers a huge asset.

For the average consumer, or a compact point-and-shoot camera is the product of choice due to their portability and ease of use. Even with these more basic models, applying a patch plate or LCD screen to frame shots taken at close range can help to significantly reduce any parallax error. For others who may want more creative control and do not mind a larger, more complex camera, cameras can eliminate parallax error together.
