    Each EV represents all the shades between it and the next highest number. 9 represents all the shades between 9 and 10. 14 represents all the shades between 14 and 15. There are 6 such divisions of shade.

    I have learn that SBR is highlight reading - shadow reading + 5. Thus shadow reading 9 and highlight reading 14 would be SBR 10.

    The incident meter value is average of apr. 5 stop range. So shadow value extends 2.5 stops towards dark from reading and highlight includes values up to 2.5 stop above reading.

    True, when BTZS is employed.
