## 3. Color Correction
Color correction optimizes the stitched 360° video by automatically adjusting vignetting, camera response curves, exposure and white balance. Depending on the videos you want to stitch you can also choose to only adjust some of the settings.

By clicking "Calibrate photometry" under "Photometric parameters" VideoStitch Studio will automatically calculate the response curves and vignetting of the used cameras to improve the blending of the stitched 360° panorama.
***Vignetting*** describes the light fall-off in the frame; corners usually appear darker than the center. Darker edges and corners are sometimes wanted in photography, but it is a problem for stitching and blending videos together.
Explaining ***camera response*** would take to much time here, but is basically the relation between the amount of real world light coming in and the video pixel values the camera takes.
