The Lab values presented on the INFO palette when reading from a 15 bit (originally a 16 bit) image are incorrect. The L value has by definition a range of 0 to 100. The info palette displays the values in terms of the value of the 15 bit number and has values in the ranges of 0 to 32767. The a* value has by definition a range of -431.034 to 431.034. Similarly the b* range is -172.414 to 172.414. The displayed numbers for a* can exceed 6000. Displayed numbers for b* are similarly distorted.
