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

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:

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!

Moderators, @Rikk Flohr: Photography, please merge this with this similar idea (which has many more votes):

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.

Do you think many "professionals" would use this to adjust their pictures?

Of course, that only applies if your science is correct.

First of all, it isn't 'my' science. There is an entire field of science devoted to color and as I wrote, 'it' doesn't care if you believe in it or not.

Have you read Fairchild's Color Appearance Models, as I have? Even the first chapter? When you do, we can discuss what I wrote about the differences between Color Perception and Color Appearance.

Maybe you are too young or inexperienced in printing color in the darkroom. I did a lot of it; RA4, Ciba, and without any Histograms, RGB values, Vectorscopes. I'm not alone.

As for this very old feature request, let me tell you my experience: over 20 years ago, while a beta for Photoshop 2.5, I requested a Saturation Curve like my good old LinoColor software. I've asked again over the years and I'm pretty sure, based on the history, I'm not going to get it. And I can live with that, Photoshop nor any Adobe produce is mine and all I can do is request features and move on.

When my partners and I wanted tools in Photoshop that didn't exist, we created them and it was a pretty solid business. One was even introduced in Lightroom Classic itself! Maybe you can find some partners to build a plug-in and actually affect the change you want. Otherwise, there seems to be strong opinions about how software should be developed, by people (AFAIK) having no experience developing software.

This would really add a lot of value for LR. I am currently editing in PP and use stills that have been shot by the same camera as the video footage in the same lighting conditions.

Using the x-rite colorchecker photo for the stills, the corresponding LR plugin gives me a correction that looks otically sound (on a calibrated monitor).

If I then correct the video parts with the help of another big x-rite chart (which sports the same tiles) and use vectorscope and parade/waveform to correct the footage manually, I end up with a quite different overall color assessment next to the stills.

IMHO the corrected videos are better, as they seem perfectly flat, therefore providing the better basis for subsequent grading.

This, in turn, means that the x-rite plugin for the stills, while doing a good job overall, certainly doesn't provide the best possible results. Hence the requested feature should be very welcome in LR.

I am thinking of creating some kind of preset lumetri correction in PP for pre-processed stills, but I am not sure (yet) if this will hold up for changing lighting situations. Intuitively, I'd say such a tranformation preset would be too static.

Note that I am at best an ambitious wannabe-semi-pro. Nevertheless, the tools provided in PP enable even me to arrive at professional looking results, while the eyballing meets muscle memory techniques on the photography said seem arcane most of the time.

Wow, talk about resurrecting an old post (6 years old).

The best answer was from John IMHO, use your eyes.

Sets of numbers, Colorimetry is about (based on) color perception. It is not about color appearance. There's a significant difference. The reason why viewing an image or print is more valid than measuring it or sampling a group of pixels, is because measurement is about comparing solid colors. And that is what the color sampling, histograms etc are based on.

Color appearance is about evaluating images and color in context which measurement devices can't provide. Colorimetry was never designed as a color appearance model. It was never designed to even be used as an interchange space between device dependent color models. It's not designed for imagery at all. Colorimetry based on solid colors in very specific ambient and surround conditions. Color in context, color we see and evaluate, that's key.

I apologize for disapointing your personal expectation of timing in the context of an arbitrarily set standard of forum viewer experience.

And I congratulate you, if "using your eyes" is your goto MO. Doesn't work for me, though, as certain genetic conditions exactly prevent you from that in the sense of achieving satisfying objective results.

That being said, your answer might be scientifically sound. Nevertheless, they are also just a "get on with it already" in the context of a real *practical* problem, like normalizing moving and still footage, that has been captured in identical situations with identical gear.

So here, have a medal for whatever.

I'm also in need of a more informative scope than just a histogram. Can't believe adobe hasn't implemented this yet. Seems like it 100% possible because they already have it in PP. I signed up for Nobe instantly! FFS adobe improve your software based on your customer whishes!

Lightroom is application for editing pictures and not really for videos. The support for video editing in LR is very rudimental. For a proper video editing you have to use an appropriate program like Premiere Pro or Premiere Elements

My System: Intel i7-8700K - 64GB RAM - NVidia Geforce RTX 3060 - Windows 11 Pro 25H2 -- LR-Classic 15 - Photoshop 27 - Nik Collection 8 - PureRAW 5 - Topaz Photo

Hi,

may I ask then how do professional photo editors manage tasks like obtaining "true" skin color values and saturation control without vectorscope?
Also, I would love to see Waveform monitor in Lightroom, as regular histogram isn't accurate enough for me.
