Today’s B&H DealZone (one-day deal) is the X-Rite ColorChecker Passport for $64.99. This is a $25 price drop from their regular price of $89.
The X-Rite ColorChecker Passport is pretty straight forward — it’s a grey card (for exposure/white balance calibration) and a 24-color patch for creating DNG profiles, all in a sturdy case. Software is included to help create DNG profiles for an Adobe Lightroom or Photoshop workflow.
