Lightroom: Add vertically aligned Parade Scopes to be able to locate under & overexposure

Please (finally) add some professional tools to allow us to visualize, recognize, and locate dynamic range and color within an image: Vertically stacked "waveform" scopes for the R,G,B and Luma. (The old, very limited histogram long ago outlived its usefulness, especially as it's presented in LR.) Vertically aligned stacking of the scopes (rather than side-by-side parade scopes) makes it easier to coordiate the different scope displays and easier to correlate with a location in the image. A vertical column in each display would correspond to the values of R,G, & B in the correspondeing column of the image. The "brightness" of a point would roughly correspond to how many pixels have that intensity value in that particular column.

The vertical scale should go from less than 0 to greater than 1, where 0 is the current black point and 1.0 is the current clipping point. (Yes, negative values have meaning!) Include a toggle to easily go from showing the available RAW data (that might have data below the black level being displayed and above the current clipping level) to showing the clipped dynamic range (0.0 to 1.0 only). The target color space (sRGB, AdobeRGB, REC709, P3, etc. plus customizable settings) would determine what the "zero" and "one" levels correspond to in the RAW data. This way, you can easily see when data exists in the base image that is being clipped in the current rendering, and where it is located in the image.

While you're at it, allow options to do away with indicating color by 8-bit 0-255 values ANYWHERE in LR. I would like the options to use either 10-bit color values (that correlate to most video formats) or the more rational 0.000-to-1.000 scale any time a color is specified. This way you can see RGB color value representations that more closely match the 12-, 14-, or 16-bit values cameras use, as well as the new ACES format. Please also report standard luma values, not "brightness" or "luminance".

I expect that a vector scope, to actually be able to show things like skin tone and color casts, would be too much to ask for, but one can only hope.

This reply was created from a merged topic originally titled More powerful analysis / scopes.

Would love to see image analysis like that found in most video editing applications be brought into the Lightroom family. Custimisable histograms, waveforms and vectorscopes would be completely invaluable for color correcting.

Not only professionals, but hobbyists coming from a video-editing environment or color-blind people would surely appreciate this kind of tools. Hey, I'm neither of those and I really want to see these features in photography software.
If Adobe can have them in Premiere or AE, they surely can have it on LrC and Ps.

i could really use a vector/saturation scope in Lr. When trying to match skin tones or just overall saturation in an image, there's currently no way of doing so in Lr. My saturation on the desktop can appear fine, but then the same image on a mobile device may appear undersaturated. Since we have no scopes nor HSL readouts, i have no way of knowing the true saturation levels in my images.

A vectorscope in Lightroom would be wildly useful for those of us who do production work. Currently, it's extremely difficult to do any sort of basic color matching in Lr and a vectorscope would make this task so much easier.
If you don't know what that is, please spend a few minutes to learn:

Premiere has the Lumetri scopes now and it should be a no-brainer to port those over to both Lr and Ps.

Both Lightroom and Capture One have implemented "grading wheels", but without scopes, they are just subjective effect sprinklers with no professional and controllable use.

If Lightroom would implement scopes, this would put Lightroom way above Capture One in terms of professional color control. And, as earth_oliver said above, Adobe already have it in Premiere - just "throw" it in there! Capture One have to build it from scratch!

Can't believe that scopes and parades are STILL not in Photoshop or Lightroom. At least give us the option!
