Any area that is supposed to be a neutral color, e.g. white, gray or black, will work. A gray is probably best because it’s the least likely to have been clipped.

The 3/4 tone is one that is midway between pure white and middle gray in your final image.

In your normal photoshop working space, if you switch your eyedropper to grayscale, a 3/4 tone will read near 25 percent. Anywhere from 13 to 38 percent qualifies as a 3/4 tone.
