Help everyone. Thank you for reading my thread.
So I've been trying to learn the Color passport and for the most part I understand the basics. What I don't understand is the white balance workflow. So do I have to take a pic of the passport with every shoot? Then create a new profile? Do i have to play with the WB on the picture first then Sync the settings to the photo I'm working with? Is there any way to work with the color checker photo and the project photo at the same time? What I'm getting at is I will have the color checker at the beginning of the photoshoot. then say Im working with a photo at the end or middle of the shoot. I have to go back, find the color checker, play with the wb then apply to my project photo? I hope this makes sense to some. Thank you kindly and excuse my frustration.

You might find the following video helpful for incorporating the CCP in your workflow. The presenter makes a clear distinction that white balance and color calibration are separate functions.

Knowing what software you are using for your processing would also be very helpful. Generally you should only need to make a profile for the lighting type that you are using once. Be taht daylight, tungsten or whatever. Occasionally when you have complex mixed lighting you might need to do a profile for specific circumstances, such as when the lighting ratios change in those complex mixed conditions. Colour temp should then be easy, a simple shot with the WB card included for each location/lighting setup as the first shot. You then simply use the eyedropper tool for picking the correct WB by clicking on the preferred "neutral" patch. The CC Passport has a couple of tone options for WB, warm, cool, as well as dead neutral, there are two sets of patches, one setup for portraits, the other for landscapes, so there are plenty of choices. Once you have clicked on the chosen WB patch that best suits your requirements, you simply use what ever option your software requires to paste the WB setting to all of the other photos taken in the same lighting.

A profile for ever shoot is not needed.
Always set the profile before WB in your workflow.

Think about this...

A. For a pro who works in a studio, perhaps with strobes sometimes, perhaps with LED constant lights sometimes


  1. use the ColorChecker Passport for each lighting type (strobes vs. LED), and create a Profile for that setup
  2. don't bother necessarily to include the use the ColorChecker Passport in a shot, but use one of your standardized Profiles to get best color accuracy
...The ColorChecker Passport in this setting is not merely an aid in establishing WB value, the creation and use of the profile help to gets color reproduction more accurate, such as for a pro shooting illustrations of textiles and fashions.

B. For the pro who is shooting on location, or for a typical amateur enthusiast
  • include the ColorChecker Passport in a shot to establish a WB setting to use during post processing

...and if the lighting conditions (the mix of lights) is different, include a shot of the CCP in those lighting conditions to help you establish 'neutral' under those conditions.

I think this Joe Brady video is actually really good, since it takes you through examples of both portrait and landscape shoots using the CC Pro and LR. I have two links, the first is the one I actually watched Link 1 (external link) and the second Link 2 (external link) I think is essentially the same content, but the vid is slightly longer, and I found clicking the Joe Brady links alongside the video in davinci953's post.

That's essentially what I did: I used my Spyder Checkr to 'profile' my monolights. One advantage of using quality strobes is that the variation in colour temperature is practically nil (~50K with Hensels), unlike with flashguns and elcheapo strobes whose temperatures sway like a car driven by a drunk (hundreds of Kelvins): thus, only one profiling shot gave me the values to plug into my RAW processor and the camera's Custom WB, this for ALL power levels. With so-so strobes and flashguns, you'd best create profiles for each power level and add them as presets in your RAW processor (the exercise will also help you suss out just how much your strobes wander from their nominal/advertised value); the Custom WB for the camera will have to suffer, though, as it can take only one value.

I've always found the Passport's use of LR profiles a bit of a chore, and when I used LR I preferred the Spyder's approach of using the colour adjustments. All of that is a moot point with non-Adobe software, of course, which brings me to my next point: not telling you here to return the Passport and buy a Spyder Checkr, but simply to use it like a normal colour card: take a shot and use the droppers to adjust the WB (of course, for critical work where colour reproduction must be spot on, and if you use LR, go right ahead and create a profile).
