Consider Resolution Before Taking Your Photograph

May 10, 2010

The term resolution is one that is used frequently in the world of digital photography and it can refer to several different areas of the process. For example, it can refer to image size, viewing size or print size. As respects digital cameras themselves, resolution normally refers to the size and number of pixels of the images that are captured by the camera.

Digital cameras are frequently referred to in terms of the resolution. For example, the camera may be referred to as having 12 million pixels or 12 megapixels. This represents the total number of pixels in an image and is a figure used by the manufacturer when they refer to the resolution for the camera at its best or highest setting. For instance, a digital SLR that can capture an image at 4200 x 2800 pixels has a resolution of approximately 12,000,000, or 12 megapixels.

Most digital SLR cameras have a least three resolution settings which can normally be accessed from the shooting menu under the heading of resolution or image size. Physically changing this setting alters the number of pixels that are captured for any particular image. The settings are usually described as small medium or large. Obviously, the larger the number of pixels in an image, the greater the resulting file size will be once the images have been captured.

Since resolution affects the image’s size and quality, the issue of which resolution you should use is one that should be considered carefully before you start taking photographs. The main question you want to answer is whether you want to print the image or display it on a computer. If you plan on printing the image a larger number of pixels are required to produce a good quality photograph.

If you’re only interested in displaying the photograph on a computer, then a lower number of pixels will work quite well and you can use a lower resolution. However, it is always best to be on the safe side and capture all your images at the highest resolution possible, and then, using a program like Adobe Photoshop CS5, you can reduce them for the particular use you want the image for.

When you work on an image with a program such as Adobe Photoshop CS5 it will involve removing some of the pixels from the image. Pixels can be added to an image to increase its size, but is always best to capture your image at the highest resolution possible in the first place.

Until next time take lots and lots of pictures!
