The quality of light

Very often I'm asked by students why the color of the same object may look different in 2 consecutive pictures?
The more obvious reason is the usage of the auto white balance on the camera, but in some occasions, we found the flash used to be defective. If the flash does not send the same amount of light each time, it can do so by changing the intensity or even the voltage to light the flash tube, sending a different light temperature.
Even if you use a ColorBalanceCoach disc to set your aperture, if the flash varies its power from time to time, even the best calibration tool will not allow you to take perfect pictures.

Take a look at the best affordables and reliable flashes on the market: Aurora
