P: RGB Parade and Vectorscope in Lightroom?

Hi
I do a lot of video editing and really like using the RGB Parade and Vectorscope.

Histogram for photos aren't as detailed. Is there any plugins or features that have similar functions like RGB Parade and Vectorscope for use inside Lightroom or maybe as an external editor?

Best regards Simon

Every year I look for a plugin or some way to get scopes I am used to using in professional color grading work into lightroom. Eevery year there is only the workaround of checking my exports in a color studio like resolve. Being able to switch out the histogram for an RGB waveform would be a GAME CHANGER.

1st and most obvious reason: Histograms are not an accurate scope for HSL work and as lightroom gets more tools to work with color, knowing the diference between 2 points too little and 2 points too much is becoming absolutely mission critical.

2nd: Color blind photographers and users without high end color accurate displays (basically everyone), but espeically the former have no built-in way of currently judging color other than by eye.

3rd: This would help balancing shots, replicating looks, and grading photos WAAAYYY easier.

If lightroom gets a waveform, it would be absolutely killer for photoshop to get one too, this would make roundtripping incredible for anyone who adds their extra pops in photoshop while doing the brunt of the heavy lifting in lightroom.

At some point in the future I will get on my knees and beg for this, until then I simple ask please Adobe, get us some good scopes, it's beyond time!

Well that's true. A relatively easy way around that is to use OBS to show only a certain area, then display that stream on that other screen. Some monitors also let you crop the screen directly, and Of course, then you're back to using your processor again. And you'll also be limited in color, where if you're outputting HDMI you might be able to output 10/12bit color.

But then you are monitoring the whole screen (with the UI) not just the image area.

Ha, at that cost, just buy a field monitor with a vector scope and have that duplicate your screen. You can buy one for $300, or a nice one for $700 and Then you have a nice field monitor in case you get into video content. As an added bonus, your computer doesn't have to calculate the vectorscope, which is pretty intensive (although in premiere it just got GPU acceleration)
And yes, field monitors are small, but you only need it for the scope, so that's no big deal.

After few years, somehow there have a solutions for "viewing" the vectorscope with 3rd party tools. The solutions had been mentioned in this disscusion. Here is the software screenshot, please ignore the language of my LRC.

Given the suite of tools across the adobe suite, wouldn't it be nice if they were more adjustable. For example, when adjusting skintones in a photograph, I'd like the ability to do a vectorscope so that I can be certain my grades or colour correction isn't messing up the skintone.

You can get skin tones right easily using Lab.

In Lab, the aStar and bStar values are key. Both should be positive values. Both should be within 15 units of each other. If the B value is lower than A, skin starts to appear magenta or pink looking. When B is higher than A the skin appears more yellow. The closer to zero, the more pale.

Here's a video on correcting skin tones without having to resort to CMYK, using Lab:

6 years later still no rgb parade lmao

I really need this tool to get skin tones values right. this was suggested already 7 years ago, but still no changes...

As a professional user, it’s extremely frustrating that Adobe still doesn’t offer scopes to check IRE levels. This feature is crucial for maintaining continuity and ensuring professional-grade work.

I first requested this feature four years ago, and I’ve seen multiple other users ask for it as well. Despite this repeated feedback, nothing has changed.

What’s the point of paying for a subscription if such essential tools are continually ignored? Please address this issue—it’s long overdue!

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.
