Monitor calibration

It is highly recommended to perform the monitor calibration on a regular basis. Color calibration is critical for ensuring that your photos will have accurate and consistent colors across devices. 

Adopting a hardware calibration device is the most reliable and objective method of calibrating a monitor. There is a number of inexpensive models most of which are bundled with software offering advanced features that allow you to manually select the target values and adjust the monitor brightness, white point, gamma, and black level.
