1. What do I need to know if
I want to include an image from the Web or a scanned image on a
slide?
Typically downloaded images from websites are NOT
suitable for print. Screen resolution for websites is only 72
dpi (dots per inch), far below the necessary resolution for printed
images.
2. I want to convert my slides
to digital images so I can use them in PowerPoint or on the Web.
Where can I get my slides scanned on campus?
CITI has a slide scanner available. Check out it's
operating instructions online.
3. If I am including a digital
image in a printed publication, what image type and resolution will
work best?
The two formats that maintain the necessary information
for commercial printing are TIFF (Tagged Image File Format) and
EPS (Encapsulated PostScript). Both formats work well on the Macintosh
and PC platforms. Deciding on which of these two formats to use
is more a question of what other applications can do to the file
after it is imported. Your page design does not need all the images
to be one format. Choose TIFF or EPS on an "image" by
"image" basis.
For professional publishing purposes, the standard
calls for images with a minimum of 300 dpi. You'll find you can
get by with less than that and still have pleasing results for
average everyday use, however, you probably never want to print
an image at much less than 100 dpi. Below that you will start
to see degradation. If you shoot for 200 dpi or higher, that should
be suitable for most general applications.
4. If I am including a digital
image in a PowerPoint presentation or on a web page, what image
type and resolution will work best?
CONTENTdM has information
on digital images, resolutions and file formats online.
