Sekonic L758 meter calibration question.

Hi, I have the color-checker passport without the Grey card, just has the white balance target so how do I take an ambient light reading for Grey to set up calibration for the meter to camera?
I do have another make of a Grey target would there be a great difference if I used that or should I put the meter as close as possible to the Grey patch on the front of the CCP?
Thanks in advance
Russ

All ColorChecker Passports have a grey card.

Hi, Thanks for the reply but they don't, only the newer version has the Grey card, on the older versions there is a white balance target and a place to put the owners name, date of purchase etc.
there is a small Grey square on the front of the card on the bottom but I am not sure if it is big enough to get an accurate ambient light reading to use in calibration of the Meter to camera.
Thanks again

The White Balance chart is a grey card. See this link: http://www.rmimaging.c​om …port_Technical_​Report.pdf

I don't use the separate WB target with mine, I start with using the gray patch next to the white patch in the row that goes from white to black.

Hi, This is the best photo I could get for the new special edition X-Rite-Sekonic ColorChecker Passport
As can be seen they have added a Grey target and this is what you apparantly need to calibrate Meter to camera.
Thanks again.

Russell, I've calibrated all 3 of my bodies and 7 lenses without using the special WB target, even though I have it available.
