EOS Capture v. 1.3 (Windows/Mac) is a remote shooting software application. It allows

the camera to be controlled and camera settings to be specified from the computer and

saves shot images to the computer. It also allows the user to take shots by pressing the

shutter button. It is identical to version 1.2 apart from the addition of the EOS Digital

Rebel XT camera to the list of supported cameras.

PhotoStitch v. 3.1 (Windows/Mac) uses a simple procedure to merge multiple JPEG

images to create composite images such as panorama shots.

ArcSoft PhotoStudio v. 5.5 (Windows/Mac) is also supplied on EOS Digital Solution Disk

v. 10. It provides powerful image editing capabilities with a sophisticated yet easy-to-

use interface.

Also included are WIA drivers for Windows XP and Me and TWAIN drivers for Windows

2000 and 98SE.

Digital Photo Professional v. 1.6 (Windows/Mac) is supplied on a separate CD. DPP 1.6

is a powerful RAW workflow and image editing application program aimed primarily at

professional and high-end amateur photographers who shoot RAW images. It uses

Canon’s own algorithms to provide fast RAW image display and processing and offers a

range of real time image adjustment functions.
