Using the Results

Using the calibration on your images.

Interpreting the AcrCalibrator Results

When AcrCalibrator finishes performing the calibration, it reports the settings it used to obtain the best match to the ColorChecker target.

Take a moment to look at the results. If any of the color hue or saturation results are at their limit (either 100 or -100), something likely went wrong with the calibration. Take a quick look at the instructions again and try running the calibration once more.

Throw Away the Contrast Settings

The following settings are used by the script to match the contrast of the raw image with that of the target. Consequently, they only apply to the raw capture of the ColorChecker target. When processing your real images in ACR, you'll want to adjust these settings individually for each image to give the best results.

  • Color Temp
  • Tint
  • Exposure
  • Shadows
  • Brightness
  • Contrast
  • Saturation

Keep the Color Settings

The following settings are the important ones. Keep these! Enter them in the Camera Calibration tab in ACR.

  • Shadow Tint
  • Red Hue
  • Red Sat
  • Green Hue
  • Green Sat
  • Blue Hue
  • Blue Sat

Saving Your Calibration

Once you've entered the settings in the Camera Calibration tab, go to the Presets tab and save your settings. Under subset, select "Camera Calibration" to make sure you're only saving the color calbration settings. then give it a descriptive name, for example: "Canon 20D #1 Daylight Cal"

Applying the Calibration to Your Images

Now, you can quickly apply the preset you've saved to images in ACR. In Bridge, you can select multiple images and right-click (Control-click on Mac), select "Develop Settings" and choose the preset you just saved.

Using Your Calibration With Lightroom

The AcrCalibrator script does not run in Lightroom, but the calibration settings you obtain from running it in Photoshop can be used to process images in Lightroom.
