1. As the compression ratio increases more of the original image data is discarded and the image quality degrades Compression also introduces defects referred to as artifacts that can create a blocky jagged look blur ring and diminished color fidelity in the image At low compression ratios artifacts are minimal but as the ratio increases they become more noticeable and objectionable You ll see the effects of high compression ratios when you enlarge the image to 100 percent in an image editing program on the computer To get the highest quality images use the lowest compression and the highest quality settings If space on the card is tight then use the next lower setting If you use lower qual ity settings and high compression beware that the image quality diminishes accord ingly Also when you shoot JPEG images the camera s internal software processes or edits the images before storing them on the media card This image pre processing is an advantage especially if you routinely print images directly from the SD SDHC card And because the XSi 450D offers a variety of Picture Styles that change the way that image contrast saturation sharpness and color are rendered you can get very nice prints with no editing on the computer lt Cross Reference Picture Styles are detailed in Chapter 3 RAW format RAW files store image data directly from the camera s sensor to the media card with a minimum of2. _ Exposure level indicator Exposure compensation amount compensation AEB range Shutiersnded Lea a reduction lamp on FE FE Lock oe Busy buSY L Aperture Built in flash recycling buSY Card full warning FuLL Card error warning Err No card warning Card 1 5 Rebel XSi 450D viewfinder display 12 Part Using the Rebel XSi 450D To ensure that the viewfinder image and focusing screen elements are adjusted for your vision you can adjust the diopter set ting from 3 to 1 dpt Simply turn the diopter switch located to the right of the viewfinder eyecup up or down until the image in the viewfinder is sharp If you wear eyeglasses during shooting be sure to wear them as you set the dioptric adjustment To set the dioptric adjustment focus the lens by pressing the Shutter button halfway and then turn the knob until the image in the viewfinder is sharp Focusing ring Zoom ring Filter mounting thread Lens controls All Canon lenses provide both automatic and manual focusing functionality via the AF MF Autofocus Manual Focus switch on the side of the lens If you choose MF the XSi 450D provides focus assist shown in the viewfinder to confirm sharp focus When sharp focus is achieved the Focus confirmation light in the viewfinder burns steadily and the camera emits a focus con firmation beep if the beep is turned on Depending on the lens additional controls may include the following Zoom setting
