setting camera
With a decent digital camera and a little practice, anyone can take pictures of acceptable quality with a camera set on full automatic. You can even take a lot of pictures not very good quality and make them acceptable later with image editing. But to extract the maximum capability of your camera and produce truly beautiful photos, you need to learn some things about the adjustments. Keep in mind that the cheaper cameras have no manual adjustments. Perhaps, with the right setting on your camera, you will capture your activities during your perfect tropical holidays..!
When do you change the settings of a camera, trying to figure out the proper exposure for the subject and lighting conditions. Exposure is the amount of light reaching the camera’s sensor when you take a picture. Generally, you want the exposure adjusted so that the image captured by the camera sensor is close enough to the actual image. The camera tries to achieve this goal when in fully automatic mode, but it is a little slow, which is why manual adjustments usually produce better pictures.
As you become more familiar with your camera, you can try different exposures for different effects. There are moments when the automatic mode is better, for example, if something happens and suddenly you have only seconds to take your picture: just switch to auto mode and take a picture! Take a photo with a white balance slightly wrong, and little depth of field is better than standing there fiddling with the settings of f-stop as a big time pass before their eyes.
To adjust the exposure, you can choose two different settings: aperture and shutter speed. The opening is the aperture diameter of the lens: a wider aperture means more light to pass through. Aperture is measured in f-stops. The larger the f-stop number, the smaller the opening. The aperture setting also affects depth of field, part of the photograph that remains in focus. Smaller apertures (larger f-stops) provide greater depth of field. A person at the scene and the cars at 5 m behind it could all be in focus with a small opening, but adequate. A larger aperture results in a shallower depth of field, which is normally used for close-ups and portraits.
