4. In the Favorites panel in Bridge, click the Lessons folder. Then, in the Content panel,

5. Adjust the thumbnail slider, if necessary, so that you can see the thumbnail previews
clearly. Then look at the 12A_Start.crw and 12A_End.psd files.The original photograph of a Spanish-style church is a camera raw file, so it doesn’t have the
usual .psd or .jpg file extension you’ve worked with so far in this book.
It was shot with a Canon Digital Rebel camera and has the Canon proprietary .crw file extension.
You’ll process this camera raw image to make it brighter, sharper, and clearer, and then save it as
a JPEG file for the web and as a PSD file so that you could work on it further in Photoshop.
6. Compare the 12B_Start.nef and 12B_End.psd thumbnail previews.
