Compare two logged readings

In LIBRARY, tap Compare, pick two readings and tap COMPARE 2/2. You see the difference in mired, kelvin and tint, and the gel to put on the second light to match the first.

Step by step

1. Open LIBRARY from the bottom right of the meter.
2. Tap Compare, then tap two readings.
3. Tap COMPARE 2/2.
4. Read DELTA B minus A, and the gel under ADD TO B TO MATCH A.

If that didn't work

Both estimates are compared, the AWB one and the gray-card one, because both are saved with every reading. To match a live light to an old reading instead, tap its chip above the controls and choose SET AS REFERENCE.
