Connecting Photo Formatting to Everyday Preservation
Applying
Internship Lessons
Now that
Meghan has begun to understand the different methods of digitizing images for
preservation, it is important to learn about the different formatting options
when digitizing photos. Also, understanding these concepts will help Meghan
with her research on connecting local communities and digital preservation.
What is
Image Resolution?
The
quality of a digital image often plays a role when deciding how or why to
preserve a photograph. Meghan has started learning about image resolution so
that she can apply these technical lessons to the preservation of historic
artifacts. The Federal Agency Digital Guidelines Initiative (FADGI) recommends
that images should be scanned with a 300-600 DPI (dots per inch) resolution for
the best quality. Interestingly, the size of the original photograph can change
this setting. The smaller the image, the higher the resolution should be; ensuring
the versatility of the digital image.
What is
Image Compression?
When an
image is saved as a digital file, it is processed with a level of compression.
This basically refers to the file size when digitized. For the highest quality
image, there should be little to no compression. However, file compression is
not a bad thing. It can often be helpful in preventing files from becoming too
large. Measuring the acceptable amount of compression with the level of
resolution can often be a tricky process.

Formatting
and Preservation
So how
does resolution and compression affect the everyday community and their
preservation efforts? Well, as Meghan has learned, the size and quality of an
image shapes the way that the image is digitized. These dynamics also effect the ease and ability of scanning and storing pictures. As Meghan continues to research digital preservation, these lessons will be incorporated into her final project on how to bring communities together to digitally preserve photos, artifacts and other treasured documents.
What
Meghan Learned Today
Storing
valuable family photos in glass frames or photo albums may look nice, but glass
or adhesive paper can be damaging to the photograph over time. Often, moisture
can build-up between the glass and the image, deteriorating the photo by
causing it to bind to the glass. When removing a picture that has stuck to glass, solutions such as Kodak's Photo Flo can be used to separate the photo from the glass without destroying or breaking the image.
