Canon Digital Photo Professional

Processing "White Balance" on RAW photos (CR2 files) in the Canon DPP software program

Place the files you want to process in a folder at a location of your choosing. I made a "DPP Test" folder on my desktop for the purpose of this illustration. Open the DPP Program and click on "Folder view" then locate the folder with your CR2 files. It may take several seconds for the thumbnails to show depending on the number of files in the folder.
There are two CR2 (RAW) files in the folder. The first one was taken without a strobe in the "Tv" mode, "Underwater" White Balance, 1/125, F 3.5, ISO 200. The second was taken with an external strobe in the "M" mode, "Auto" White Balance, F 5.6, 1/250, ISO 80. The White Balance adjustment in DPP can enhance the colors in both photos. I started with the non-strobe photo. Highlight the thumbnail then click on "Edit image window"
Your DPP screen should now look like this.
Click the "White balance adjustment" eyedropper tool on various white, off-white or black parts of the photo to obtain the desired color effect. You can use the drop-down menu and click on "Shot settings" to compare the differences between the two. I used the eyedropper on the indicated spot.
Complete the rest of your adjustments at this time or on the JPG later in Photoshop. Make a JPG from the RAW photo by clicking "File" then "Convert and save". A window will open (not shown here) asking you where you want to save the file and under what name. I used the same folder and same name so as to be able to easily match the RAW file to the JPG file.
If you want to process the CR2 files in Photoshop instead of DPP you must first dowlnoad a RAW plug-in from the Adobe website and install it in PS. Check their list of supported cameras and compatibility with your version of PS.
This window should appear during the JPG processing. Close this window when done or check the "Close dialog when finished" box. Now click on the "Main window" button to return to the folder for processing the next photo.
There are now two thumbnails of the same photo. One is the RAW file and the other the JPG. Both have been edited alike.  Highlight the next photo and repeat the processing steps.
I used the eyedropper tool in the indicated spot to obtain the colors I liked. Then I did a "Convert and save".
The end results are both photos processed and converted to JPG's
When exiting DPP this dialog box will appear. It doesn't matter whether or not you save the changes to the CR2 files as you can always revert back to the original photo settings as shown in the next step.
You can revert back to the original RAW photo settings when re-opening a CR2 file by clicking on "Adjustments" then "Revert to shot settings".

Below are both JPG photos after some additional editing such as auto levels and/or auto contrast, sharpness, brightness, cropping and re-sizing in Photoshop.
