Press Release Body: [1-jul-08][Omaha-Nebraska-US] Converting images from prints now
Scanners are large tools, negatives, and slides into a digital form for the purposes
of storage, editing, and sharing via the internet or to produce actual prints. The
quality of the images from a scanner depends in large part upon resolution. Some
scanners offer significantly higher resolution than others but most allow the user
to adjust the resolution used for any given scan.
Because higher resolution means more detailed and higher quality images why would a
user ever select to lower resolution? There are actually a couple of reasons why
someone might choose to change the resolution downward when scanning.
One reason that the choice to use lower resolution would be considered is that
higher resolution images contain more information. The downside of more information
is that file sizes are much larger, requiring much more storage space. When storage
space is limited, higher resolution images can be a drawback. Users must experiment
to determine what level of quality they are willing to accept in order to preserve
memory.
In addition to the increased storage needs, the larger file size of high resolution
images creates a second drawback. Such images are slower to scan, manipulate, and
download. A user may not wish to spend exorbitant amounts of time dealing with
larger file sizes and those receiving or waiting for a web page to open that
contains such files may become impatient with the process as well. Again, the user
has to determine how much image quality they are willing to sacrifice to get smaller
files that save time.
Determining what resolution to use when scanning can depend on a number of things:
the type of material being scanned, the quality of the image, and how the resulting
file will be used.
Slides and negatives require a higher resolution than a print. Because they start
off quite small, they will likely be enlarged for viewing purposes. When any image
is enlarged, greater resolution is needed to maintain acceptable image quality. The
number of pixels or bits of image information needed for the enlarged image to be of
reasonable quality
If an image being scanned is a text document less information will be needed to
create a clear image and, indeed, a resolution of only 100 should be sufficient. If
the image scanned is a picture that will be shared only via computer, then a
resolution of 100 or so may still be quite acceptable as the resolution at which a
computer screen is able to display is generally limited. However, if that same image
will be printed, resolution will need to be greater; perhaps 300 to obtain an
acceptable image. Just as explained when scanning slides however, if a user chooses
to enlarge that same image, greater resolution will be required to maintain quality.
For instance, if a 4x6 print will be scanned and enlarged to a 10x15 print, then a
resolution of at least 600 would be wise.
Clearly, scanning images at the highest resolution can create optimum image quality
but when speed of scanning and downloading are important or storage space is
limited, users are wise to consider adjusting resolution downward in situations
where acceptable image quality is possible with lower settings. Some experimentation
will be required to find the level of image quality that is acceptable to an
individual user.
