The following information applies to flatbed scanners and Adobe Photoshop, and is meant to familiarize users with common commands and tools in various systems.
You will want to scan your original in one of the following modes depending on the image:
1. A Preview Scan is the first command you want to execute to check your scan settings. You will also want to choose:

Powerpoint presentations can be saved in PPT or PPTX for PCs and in the ’98 version for Macintosh. It is recommended that you save your file in the most recent version of Powerpoint since occasionally changes can occur in backgrounds and symbols when converting to a higher version inhouse after you have dropped off your file. You may save your file on a flash drive when dropping off files for processing into slides. Requestors also have the option of emailing their presentation to the Media Staff folder (type Media Staff in the name section of your email). Please be sure to also send a reminder email to either Bred Boudi to let us know to look for your file.
Please consult Media Services staff when attempting to incorporate other graphics program files such as Canvas into your presentations. Occasionally problems arise in file size and compatibility. If possible, save your image file as an EPS or TIF file to insure that it can be opened in Photoshop. This will allow for a translation into many different file types. If scanning your own images to be used in Powerpoint, please be sure to keep in mind that unless you are planning to print out the image at a high resolution, it is not necessary to scan at anything higher than 72 DPI. This is due to the fact that standard monitors will not be able to show images higher than 72 DPI, even if the original was scanned at a higher resolution.
If you’re reading this, you’re obviously interested in digital imaging in at least some of its myriad forms.
This tipsheet is meant to get you started, help you understand jargon, realize the possibilities, think about considerations and point you in the right direction. There are also separate tipsheets for:

Commonly Used Web Formats
Commonly Used Desktop Publishing Formats
Many scanners/cameras come with their own file format based on their software. Check the program to make sure you can either manipulate the image within the program or export it to another program where you can manipulate it.
Interpolation: Interpolated resolution adds pixels to the image using software to determine what color they should be. It is important to note that interpolation doesn’t add any new information to the image, it just makes it bigger.
