How to Edit JPEG Images in ImageBrowser EX on Your Canon EOS 6D

By Doug Sahlin

You can view all images you download in ImageBrowser EX on your EOS 6D, but you can edit only JPEG images. You can select RAW images in ImageBrowser EX and then edit them in Canon Digital Photo Professional. When you opt to edit a JPEG image in ZoomBrowser, you can correct red-eye, adjust sharpness, crop the image, apply an auto-adjustment, and insert text.

You can adjust the color of a JPEG image in ImageBrowser EX. You can also change the brightness and saturation. You can even adjust the RGB (Red, Green, Blue) channels and levels as well as use the Tone Curves Adjustment menu option to adjust brightness for different tone values. To adjust image color:

  1. Select the image you want to edit and then click the Edit button.

    The menu drops down to reveal the editing options.

  2. Click Edit Image.

    The Edit drop-down menu appears.


  3. Select Adjust Color and Brightness.

    The Color/Brightness Adjustment dialog box appears.


  4. Drag the sliders to adjust brightness and saturation.

    The settings you choose are a matter of personal taste. Don’t go too far over the top with saturation though because you might create some colors that can’t be printed. It’s also a good idea not to increase saturation when editing images of people. When you increase saturation, you amp up all colors including the red tones, which affects the skin color of people in the photograph.

  5. After you make your adjustments, click the Save As button.

    A dialog box appears, telling you that some shooting information might be lost. Click OK and the Save As dialog box appears. You can only save the image as a JPEG file. However you can rename it and specify the folder in which the edited image is saved.


  6. Enter a filename and specify the folder that the image will be saved to.

    Image editing is destructive. Consider giving the image a different filename and storing it in a different folder. That ensures you’ll have the original image to edit at a later date.

In addition to adjusting the brightness and saturation, you can adjust the color for the red, green, and blue channels by choosing an option from the Color Adjustment tab. This is fairly advanced image editing, as is Correct Levels. The Tone Curve Adjustment option lets you adjust tonality in specific brightness ranges. This option is useful and fairly easy to master. To adjust the tone curve of a JPEG image:

  1. Select the image you want to edit and then click Edit.

    The menu drops down to reveal the editing options.

  2. Select Correct Tone Curves.

    The dialog box refreshes to show the Tone Curve Adjustment dialog box. The diagonal line is the tone curve. The line isn’t a curve now because it’s applying brightness information in a linear fashion: from shadows, to midtones, and then to highlights. When you add points for different tonal values along the curve and drag them to adjust brightness, you see a curve.


  3. Click a point on the curve to make an adjustment for that tonal value.

    Click a point near the bottom of the curve to modify the brightness of shadow areas, a point in the middle of the curve to change the brightness of the midtones, and a point near the top of the curve to change the brightness level for highlights. After you click a point, you see values in the Input and Output text boxes.


  4. To adjust a point, drag it up to make the tonal range brighter or down to make the tonal range darker.

    You can also change the value in the Output text box. A typical use for a tone curve is to apply more contrast to the image, with one point near the bottom of the curve, one point in the middle of the curve, and one point near the top of the curve. Note the input and output values for the shadow, midtone, and highlight points.

    The value for the middle point hasn’t been changed, which is smack-dab in the middle of the tonal value range. Doing so would increase the overall brightness of the image. Brightening the highlights and darkening the shadows increases image contrast.

  5. After you make your adjustments, click Save As and then in the Save As dialog box, follow the prompts to save the image.

    When editing an image, you can compare the edited image with the original by clicking Show Original Image in the lower-left corner of each editing task’s dialog box.
