Early on in every photographers career, we learn of the important factor that screen calibration plays into the outcome of our photos. It can make all the difference in the world when it comes to our final products, especially our prints. Programs for calibration can be expensive, and many photographers, especially ones starting out don’t always have the financial resources for these tools.
Thanks to H&H Color Lab, we now have an alternate way to monitor color calibration by using some basic tools within Adobe Photoshop, and combining them, to validate accurate color calibration. Source: Monitor Color Calibration Using Photoshop
