Popular File Formats for Saving Digital Images

TIFF – Can be opened on both PC and Macintosh computers. Best choice for preserving all image data, but usually results in larger file sizes. Don’t use for images on a World Wide Web page.

JPEG – Can be opened on both PC and Macintosh computers. Can compress images so that files are smaller but too much compression reduces image quality. One of two formats to use for Web images.

Popular File Formats for Saving Digital Images

GIF – Use of Web images only. Compatible with Macintosh and PC computers. Offers a feature that enables you to make part of your image transparent so that the Web page background shows through the image.

BMP – Only for images that will be used as Windows system resources, such as desktop wallpaper.

PICT – Only for images that will be used as Macintosh system resources, such as desktop pattern.

Options Available

When developing 35mm film, pictures can be transformed into digital images and offer the option of saving them on a CD.

Some developers email you back your digital photos directly for download, thus skipping the compact disk entirely.

New disposable digital cameras – have to wait for processing but companies like Kodak, give you a free CD but will still have to pay the normal develop and print fee. The CD is compatible with both PC and Mac systems.
