a Digital Image for Use in Powerpoint
- Scan image into
Scanner using DeskScan II or other scanner application
Scan at 72 dpi
Set the selection marquee to your monitor's aspect ratio
When possible, create the marquee at 800 by 600 pixels. Adjust software
settings to 120% (or percentage needed) to scan the image full size
Adjust auto tool contrast/balance levels
- Save into a folder
on the desktop as "pwrpnt.tif" file
The default file type is usually as a .tif file. Even if you are able
to save as a .jpg file from the scan software, do not do it at this
point. Every time a .jpg file is worked on and saved again, the .jpg
lossy compression throws away parts of the image. Repeated saves and
subsequent lost data compression deteriorates the image.

file in Photoshop

ratio, if necessary, to fit your presentation monitor; one default setting
is 600 by 800 pixels

in the file. This uses the default settings. As you progress in PhotoShop
you will go to the advanced tools and adjust the levels with more specific
control. The default settings often correct initial scans quite well.

choose Sharpen. This, again, uses the default settings and you will
want to progress to the advanced Sharpen Mask controls as you
