I have created a custom profile but it is custom to a particular camera and sensor. Not that hard to do. I expect you are referring to the 758 dr. It is a piece of cake to profile. Y ou also get to decide how close to clipping points you want the warnings. That is a personal thing. It was an eye opener and confirmed the increased dynamic range over my prior d700.

This is for a Sekonic L-858D-U. I went ahead and just ordered the X-Rite ColorChecker Passport Photo, and will create the profiles myself. I'm kind of disappointed though that a $600 meter didn't come with a basic card to calibrate the camera's dynamic range though.

The color checker passport can be used at the start of any series under a particular lighting set up and can be used to get accurate color then precisely warm or cool it. Do it in lightroom in the first shot, make the correction then all other shots will be corrected as they come in.

Sure, but that is not a profile of the camera sensor when taking a light reading, it is simply a WB adjustment. The OP was looking for a means to store the D850's DR sensitivity in the Sekonic meter so while lighting one can tell clipping points. That can be done with the ColorChecker Passport if you use the Sekonic Data Transfer Software but is less accurate than the Exposure Profile Target II.

I understand the op is looking for setting clipping points. As they say in the tv commercials, but wait, there's more. The ccp can be used for color as well. What is your source that indicates the $132 Exposure Profile Target II is more accurate when calibrating the meter? In the videos for Sekonic that Joe Brady made, he uses the color checker passport and I don't recall him saying the profile target was more accurate. Also, if it is less accurate, how much less accurate? I have set the clipping points on 2 cameras using the CCP and it has worked fine and the CCP is a multi tasker in that it can be used as a color profiler as well and fits in my vest for portability.

In the Sekonic DTS software manual it states the Exposure Profile Target II will provide a smoother calibration. Also note, the CCP does not have an 18% grey patch.

Is a smoother calibration more accurate than the ccp? Is it worth the extra $100+? In the videos Brady made for Sekonic, he uses the ccp. 18% gray is an inaccurate measure of exposure. In 1970, I purchased my first 18% gray card from Kodak at the store in Rochester and it came with a small slip of paper with the instruction to take a spot reading and add a half stop. What the heck? Each camera and meter mfgr has it’s own standard of 18% gray and each sensor can be different so an 18% gray patch or card isn't as accurate as using a meter calibrated to the sensor. The ANSI standard for camera meters is actually is 12.5% gray not 18. I calibrate my incident/reflective meter to my camera. The ccp can be purchased with 2 full sized patches, white balance and 18%. I can get within gray card accuracy using the spot meter on my camera knowing the tones of various colors, in particular, my palm or anyones palm since they are nearly the same tone on any race. Spot the palm, add 2/3 stop light. No need to have a gray card, like Carl Malden used to say about mastercard, I don't go anywhere without it. Or find colors like coca cola red, school bus yellow, electric cord orange and zero out the meter, they are "18%." Pastels, add one stop of light. Close enough for government work as they say. Better than a WAG, wild ass guess, but still not nailed. In studio, the meter lives in my right vest pocket, ccp in an inner sealing L pocket. Not only does it nail exposure, it allows repeatability and speed.

What ever works for you, keep doing it. I offered the Exposure Profile Target II as an alternate that will be more accurate than the CCP but if you are happy with your results, keep on keeping' on.

That is one of how many videos? I can list a half dozen where he uses the ccp. I didn't hear him say it was more accurate. But if I can get more accuracy I would be glad to spring for it but, I haven't seen anything indicating it does. I'm not disputing your claim, just interested if I can fine tune even more as it is an intregral part of my work flow. I just want to know who says it is more accurate and why.

I guess you haven’t read the Sekonic DTS software guide then, page 12.
“ColorChecker is an X-Rite Incorporated product.
In the same way as Exposure Profile Target II, camera exposure profiles can be created using test shooting either in the Normal Mode producing three shots (standard exposure, +3EV and -3EV) or the Expansion Mode producing five shots (standard exposure, +4EV, -4EV, +8EV and -8EV). Note however that profile created with the Color Checker will be not as accurate as with the Exposure Profile Target or Exposure Profile Target II.”
Sorry!
I am sure it has something to do with the software alignment of the card via the 4 crosses. So it will analyze all the grey patches as it developed a profile. Those patches do not exist on the CCP.
