Canon EOS 20D SLR Review

Pressing the (Play) button brings up the last image stored full screen on the LCD. The current folder and file number is in the upper right corner, down in the lower left is the shutter speed, aperture, current image number and total number of images.

While viewing a picture full screen you can press the INFO button to see all the exposure details. The current image is displayed as a hi-res thumbnail with a histogram to show the dynamic range, the color space, ISO speed, recording mode, shutter speed, aperture, exposure compensation, flash exposure compensation, white balance, metering mode, image size and quality, time and date.

Another feature of the info-playback thumbnail is that it will "blink" the area of the image that it deems will be overexposed. You can use this as a visual warning that you might need to adjust exposure compensation and re-shoot the picture.

Pressing the (Index-Reduce) button will bring up a thumbnail preview index so you can quickly select an image to display. Pressing the Jump button enables you to move a page at a time through the stored images, your position is indicated by the slider graphic in the lower right.

Press the (Enlarge) button to go into Zoom-Playback mode, each time you press the button the image is magnified more until you reach the maximum of 10x. You then scroll around inside of the image by using the Mini-controller button.

The Play Menu has options to Protect/Unprotect images, Rotate images, set Print Order info, start Auto Play slideshow and set the Review time.

Use the Auto Rotate menu option to display portrait mode images on the LCD (and TV) in correct orientation. The camera has an orientation sensor built in that will detect when it is used in vertical mode and embeds this data in the header of the image file. The Canon Image File Viewer and ZoomBrowser also use this data to properly display images.

The Protect mode lets you tag an image so that it cannot be accidentally deleted.
