SpyderCheckr24 and photography:
If accurate color reproduction is what you're looking for, the capabilities of the Datacolor SpyderCheckr24 are second to none. The only way to ensure that a camera's color calibration is under control is with a color chart and analysis software, such as SpyderCheckr24 and its SpyderCheckr24 software. This allows you to accurately calculate a set of correction values, which can be used as an HSL preset in Adobe Photoshop, Adobe Lightroom, or Hasselblad Phocus. Start color control at the capture stage with the new Datacolor SpyderCheckr24. 
Color Calibration - Allows photographers to color calibrate their cameras, perform in-camera precision white balance, and record samples of known colors. 
Consistent Color Capture - Datacolor SpyderCheckr24 helps capture consistent color from day to day and camera to camera and easily apply these results in your workflow with RAW import software such as Adobe Photoshop and Lightroom.
Color Patches - Rugged, eco-friendly design features 24 spectrally engineered color patches, easy-to-use calibration software that streamlines post-production by getting consistent, predictable color from the start.

SpyderCheckr, Video and Black Magic Davinci Resolve:
Imagine shooting an interview: in order to switch between multiple perspectives later during editing, you use three different cameras, each equipped with a different sensor. Even if you adjust the white balance and hue in the camera settings and set them exactly the same for all cameras, each sensor reproduces skin tones slightly differently. This is because each camera has a different color profile.
The default color behavior of a camera depends on the manufacturer and differs between camera brands. This makes it difficult and time-consuming to adjust colors in post-production, adding unnecessary stress, especially on projects with tight deadlines. However, if you hold the SpyderCheckr24 in front of the on-camera interviewee at the start of the shoot, you'll be able to adjust the different cameras and their color profiles with just a few clicks in DaVinci Resolve afterwards."
