Best Practices

Start Big:   When in doubt about how you might end up using your images, opt for the highest resolution possible. It is always better to start out with the most information possible, and then scale down as necessary. If you start out with low resolution, you cannot get a higher resolution without scanning or taking the picture again with higher resolution settings, and you may not get that chance.

Protect Originals: Keep the original, high-resolution versions of your images (which should be in TIFF format, if possible) in a separate place from your working documents or optimized Web images. Back up your important documents on some kind of external storage medium (CD-Rom or fire wire drive, for example). This will help to ensure that you have something to go back to and work from should something unfortunate happen to the other files.

Name Files Accurately: Develop a file naming convention that will help you accurately identify your files. Names that include descriptive information, version or size information, or intended use information can be helpful when managing large digital image collections.
