Canon EOS Viewer Utility (

After starting EOS Viewer Utility the main window is displayed, it is divided into four panes; Folder list (top left), Bookmark (bottom left), Thumbnail display (center), Histogram / Information / Notes (right). Additionally the Tool Palette Window may also be displayed which allows you to make RAW adjustments in thumbnail or single view modes (see below).

Thumbnail index view

Thumbnails shown can be from your computer (or network) or connected camera. Double click on a single image to open the single image view window (see below). Images can be organized or manipulated individually or as a group (by selecting more than one image). Icons along the toolbar allow you to rotate, check / uncheck, protect / unprotect, modify IPTC data and erase images (among other functions). Select a single / multiple RAW images, right click and select 'Convert and save in file...' to display the save dialog.

Single image view

The single image view window enables a large view of the chosen image and can be manipulated on its own, this includes RAW adjustments provided by the Tool Palette window (see below). You can change the magnification level and pan around the image. Select the 'Save File' icon or right click and select 'Convert and save in file...' to display the save dialog.

Tool Palette Window (RAW adjustment)

Press CTRL+T or select 'Tool Palette' from the View menu to display the RAW adjustment tool palette. This window allows for adjustment of RAW parameters for RAW images. This small floating window can be used in both the main window thumbnail view (with one or more RAW images selected) or in single image view. Settings applied to an image are memorized by EOS Viewer Utility. You can also copy and paste settings between RAW images.

Images are saved to the local hard disk (and optionally also the storage card). Settings are adjusted by clicking on the setting on the display panel and pressing the left or right adjustment arrows. Additionally you can also execute 'Timer Shooting' (time lapse) which can be configured to take an exposure at specific intervals.

EOS Capture immediately after startup displaying current camera settings. Click on the camera icon to take a shot. Click on any of the 'adjustable' settings (such as aperture, white balance, ISO etc.) and use the left / right arrows to change.
