Canon Digital Photo Professional

Canon actually provides two ways to edit RAW files: ZoomBrowser EX and Digital Photo Professional. ZoomBrowser EX is clumsy, provides very limited editing features of RAW files only through an additional Canon-provided program called RAW Image Task, and is excruciatingly difficult to update. Our advice, after trying both: use Digital Photo Professional instead. You can install it from the CD packaged with your Canon camera, or download it from the Canon website.

Using Digital Photo Professional to Edit RAW Files

Digital Photo Professional (DPP) bears a striking resemblance to Adobe Lightroom. And, you can consider it a sort of "junior Lightroom" for Canon RAW files. Here's how to get started:

1. Open DPP

2. Select a RAW image created by a Canon camera (.CR2 or .CRW).

3. Click Tool to open the Tool palette.

4. From the RAW tab, use sliders to adjust brightness, white balance, picture style, contrast, color tone, saturation, and sharpness.

6. Use the RGB tab to adjust tone curves for RGB or separate channels, brightness, contrast, hue, saturation, and sharpness.

7. Use the NR tab to adjust noise reduction.

8. Click Tool to close the Tool palette.

Note: If you prefer to work with full-screen images, double-click the image in Step 2.

Using DPP to Save Changes to a RAW File

1. After editing a RAW file, click File, Save As.

2. Navigate to a different location if desired.

3. If you don't choose a different location and you don't want to overwrite the original file, enter a new name for the file.

4. Click Save.

5. A new RAW file is saved to the specified location.

6. If you have selected multiple files (see "Processing Multiple Files" for details), you will be prompted to save each additional file.

Saving a RAW Image as a Different File Type

1. Click File, Convert and Save.

2. The saved file uses the same name as the original file. Enter a different name if desired.

3. Select the image type (Exif-JPEG is standard; you can also select 8-bit or 16-bit TIFF, with or without JPEG image).

4. If you select an output option that includes JPEG, the image quality defaults to 10 (best).  To decrease file size (and reduce quality), use the slider to select a smaller value (1 is smallest/worst quality).

5. Select the desired resolution.

6. Click Save.

7. The file is converted and saved.
