Lightroom: Add analyze of Hue, Brightness, Saturation of Color

Recently I developed a series of photos taken in a restaurant. There were spotlights. People near the table had a yellow cast in the face, people sitting back from the table had a blue cast in the face.

Here I realized how underdeveloped the analyze tools in Lightroom are. Actually there are no analyze tools, except the histogram and the color picker for the white balance. All this tools focus on RGB, which has no real meaning to humans. RGB is very technical.

My goal was to adjust the skin tones of two people in one shot to match more or less. To archive this goal I had to match the Hue of both faces. Seems simple, but I realized:

  • There is no way to measure color or brightness in the photo.

  • There is no way to compare the color or brightness of multiple spots.

  • There is no way to detect a color shift in a part of an image.

I would suggest the following features:

A: Eyedropper Enhancements

  • Add an independent "eyedropper" tool which is not bound to the white balance, and also works while masking an area.

  • The eyedropper tool shall show the colors as RGB and as HSB.

  • One shall be able to configure the sample size between 1 and 101x101 pixels.

B: Histogram Enhancements

  • There should be a visual view of the HSB color information, featuring a line where skin color is located. This is well known in video editing as "vectorscope". It actually helps to detect color shifts and optimize skin color. Here an example from a video editing software:

  • There should be a way to see the histogram only for a selection of a picture, without the need to crop it.

C: Color Analyze Pins

Usually one likes to keep the color values in view while he is adjusting parameters of the picture. Actually you have to move the white balance picker into the picture, and use the cursor keys to adjust white balance values to see the result. This is strange and not very comfortable.

  • There shall be "color analyze pins" which can be placed at points of interest in the picture.

  • Each pin is fixed to a certain location and has a given sample size from 1 to 101x101 pixels.

  • Each pin always shows the current color value at his location in RGB and HSB.

How to use these pins:

  1. You open a new picture.

  2. You place a pin at a critical bright part of the image.

  3. You place a pin at a critical dark part of the image.

  4. You place a pin at a skin color you like to correct.

  5. You start adjusting parameters and keep watching how to color values at your defined locations change.

Some interesting ideas, but just a note: you can see RGB values at any point in the histogram, which means there is a way to:

* measure color or brightness in the photo.
* compare the color or brightness of multiple spots.
* detect a color shift in a part of an image.

Not sayin' you won't need a notepad if you're planning on normalizing multiple photos etc., just sayin'...

Rob, did you read the OP paragraph 2? :*)

Yes, and I agree: one has to mentally translate from R, G, & B to H, S, & L or whatever. So, +1 vote for other options..

But to reiterate: one CAN "measure, compare, and detect..", even if not in preferred fashion - from the OP's statements which followed paragraph 2, I wasn't sure it was clear.
