Image resolution refers to the size your image appears on a
computer monitor rather than the physical dimensions an image
will print. The pixel dimensions of an image identify the
resolution. Many digital cameras let us change image resolution.
So, before we take a picture, we must determine the quality of
an image first by using the highest quality setting available on
the camera. Therefore, set your camera for the best image
quality if you want to obtain high quality photos.
According to the article “Image Quality – An Explanation” by
Julian Foster which was posted at www3.teleplex.net, a truly
high-resolution digital photo can be anywhere from 12MB (for a
4-by-5-inch image) to 70MB (for a two-page-spread photo). The CD
ROM photo collections currently on the market have files ranging
in size from 500K-22MB. He added that image resolution, the
amount of information in a digital file, is measured in dots per
inch. Screen frequency, the density of the lines of dots used to
print a continuous-tone photograph, is measured in lines per
inch. Newspapers typically use a coarse line screen of 85 lpi;
in-house publications, 100 to 120 lpi; and glossy magazines &
good quality offset lithography, 133 to 155 lpi.
Proper resolution is truly important for good printing. And to
achieve this, you must always remember some rules that include
the following: the text must be 400dpi at the final size in the
layout; the images must be 300dpi at the final size in the
layout; the dimensions of the resolution and size are inversely
proportional to each other so, if you enlarge an image, you
lower its resolution and if you reduce an image, you increase
its resolution; how an image is originally acquired will
determine its resolution and thus, the size it can print at for
clear and crisp printing; and low resolution images print with
jagged edges and appear fuzzy.
Indeed, when deciding on the print size of your image, you must
choose a size that is appropriate to the resolution of the image
you are supplying. The size to which your image can be printed
without a loss in quality depends on the resolution of your
image. Remember that the higher the resolution of your image is,
the better the quality of the image when printed.
Most digital cameras allow you to select a combination of
resolution and quality from the settings menu. In order to
obtain an optimal print out, you must set your digital camera at
the highest possible resolution and quality. Always remember
that the higher the quality, the larger the image file will
become. So folks, make sure you have sufficient room on the
memory card!
