It's a neat little device. It's a very good starting point, even if you plan on making adjustments in post.

I use mine 3 to 4 times a day every time I shoot. It cuts down editing all my pictures when I can batch edit them all at once.

1) Why is the ColorChecker so expensive !!

Because people will pay that much.LOL

2) Why do you need all of those colors and shades of gray? Isn't 18% gray all I need?

All the colors makes a profile to make sure all the colors in your image is correct.

3) If I set up my lights and shoot the ColorChecker, do I then simply apply the same correction from that shot to all of my images from that lighting set-up?

Yes you need to have a profile for every setup and power change.

4) If I change my lighting in any way (intensity, arrangement of lights, modifiers) do I need to shoot the ColorChecker again?

yes

5) Can't I get the same white balance correction using a less expensive 18% gray card that I can get from B&H for less than $10?

Gray color works for WB, but the color checker corrects for the camera color. Nikon and Canon have different color values and this will make them all equal before editing.

6) How often do those of you with the ColorChecker actually use all of those colors, and can you give some examples of how you used them?

It use the 4 corner to align the chart and sets all the colors to fit x-rites profile to make a new profile for lightroom/ACR.

I hope I answered the questions right. :)

Thank you for all the excellent information.
So if I understand what you are all saying, the X-Rite ColorChecker Passport will help me with white balance AND color accuracy. I understand how it will help my white balance, and the color cast that I sometimes get can easily be fixed, but I'm having trouble understanding how it will ensure color accuracy.

Are all of those swatches precise colors (like pantones are)? And if so, how do I get Photoshop to evaluate those color swatches and make the necessary corrections? Is there a sampling "eye-dropper" that I click on the colors like when I'm sampling white/black/neutral gray? --- Just how do I get Photoshop to use those colors?

It sounds like the ColorChecker may have some benefits for me, but I want to fully understand how it works before I try justifying spending that much money for a little plastic case with some colored squares printed inside !!

It is in LR3

Yes the y are precise colors. the eye dropper can be put on teh warming or cooling grey.

You have to down load some software to make it work.


Don't try to confuse me with the facts, my mind is already made up.

I'm not sure I understand what you're saying, sigma pi.

Are you saying that LR3 has a tool that I can use to sample all of the color swatches in the ColorChecker, and then it will correct all my colors to ensure accuracy?

Or are you just saying that I can sample one of the shades of gray (other than the 18% box) and warm/cool the color temperature of the image. ... Because that part was obvious. --- I'm trying to figure out what to do with all of those color samples.

Theres a CD that comes with the passport, it contains software and plugins to make those color swatches into a color profile.

I believe it has a ACR and LR plugin.

There is a thing you down load (the CD did not work for me) from Passport that is a plug in in LR3. Then yes you can have your colors matched / accurate / a bit saturated some times.

OR if you are not happy with that they have different shades of 18% gray that you can warm or cool the photo. there is one row of the gray.

you can go either route. I usually do the first and adjust to my liking.

There are several videos explaining it on the X-Rite website (external link).

And here is another video in Amazon reviews (external link), scroll down to the first review.

If you are (or know) a student/teacher, you can get this at a small discount with a MAC discount. I don't know how much it is now, but last year it was about $20 off.

You don't do any of the evaluation and you don't have to do any more than create the profile and then apply it, as in answer #3 in my earlier post:

https://photography-on-the.net …hp?p=12253407&p​ostcount=3

I know it can be confusing but it's actually a very simple procedure and one you won't even think about after you do it once or twice.
