Last week, in our continuing look at DIY Photography in our 'Photography Monday' Video Corner videos, we learned about monitors & calibration. This week we take a look at "Delta E Tolerance" - what it is and how to test your tolerance with the Pilot Color Tolerance Exercise. Obviously, unless you get very serious about printing your own photographs, this process is not necessary for you to go through. That being said, it's never a bad idea to know what goes on behind the scenes at your favorite printing lab, right?
