PS CC - Measuring Hue to find its Compliment

[preditorj40153117]

In both video and photo there is often a hue to photos especially from consumer cameras. I have also shot with high end pro-cameras that were set to the LCD and not a calibrated monitor.

The color profiles in PS or PrP do not in any way depend on the monitor so i do know that the value of color that i see may be slightly different on another screen. In Premier i have the ability to look at my scopes and see the RGB values in the trace and then using my own discretion in conjuction with my knowledge of my screens to balance the image.

But there has to be a way of measuring hue in a way to get an actual value and then maybe a formula to determine its opposite so that i could use one of many methods to remove that particular hue.

How do i measure a hue and see the values?

Is there a way to do this in PS & PrP?

Note:

I can get closer to an actual value in PrP(PremierPro) and AE. But that only because i can see it in the YUV Vector scope.

You can use the eyedropper tool and the info panel to display values.

If you click on the eyedropper in the info panel a menu appears where you can select what you want to show (in your case HSB)

After I wrote this I got to thinking did you mean a single value for the whole image.

So I tried this>

Use image - Image size to temporarily resize the image to 50x50 pixels ( I started with a square image).

Then set the eyedropper to average 100 x 100.

No matter where I put the it on the image I now get the same Hue value

Not sure how accurate it is - but it may help with your thinking

Edit to add - after measuring just click in history panel to go back

If you really want to balance by the numbers though, the better way is to photograph a Color Checker in the same light and use that to adjust and apply it to your image

I am post 60% of the time. (especially on photos) So i do not have control over the set. When i shoot i use a color card. I'm just in the mids of balancing a 3 camera shoot of Timelapse photos. Its like 15,000 frames from a Cannon, Nikon D3, and a GH3. They did some balancing of the cameras on the shoot but the are all off in a different way (D3 being nearly perfect). One is a touch yellow another is a touch magenta.... ect.

As the post guy on this one i just need to figure out a faster and more accurate workflow for this kind of CC. I tried to CC 24 frames using judgement and i can see the slight shifts thru the frames with no consistency. 2 of the cameras are well balanced but with the hue, so i believe that if i could measure it in one frame i could automate. The Cannon and the GH3 are consistently hued thru their individual runs so these could be made to match the D3.

That 50x50 method may just work. I will try it when i start the project tomorrow.

Sorry if I posted a bit of the obvious, you can't always tell whether you are answering an experienced user or a relative newcomer to Photoshop.

Hope you get sorted .
