P: RGB Parade and Vectorscope in Lightroom?

Topic: Vectorscope

Just posting as a request for vector scope in lightroom classic

Darktable, 3dlut creator, rawcolor app have vectorscope. acr/lr for quick editing processes.

This is what a vectorscope looks like. The pattern shows how it looks with SMPTE color bars as a source. The dots in the little boxes on the graticule (face markings) represent where those colors should be. We shoot a very accurate color bar chart to set up and match the colors coming from multiple studio cameras.

You'll notice a vector running to a position that is about 10 o'clock opposite the -I vector. We sometimes call this the flesh vector. Regardless of a subject's skin color, it should always line up with this vector. It will, if everything else is set right, but most camera shaders (the person who does the camera matching) will put sombody in front of the cameras, get a close up, and use this vector to make sure the vector matches on all the cameras. A good shader (or editor, for that matter) will never totally trust what they see on a monitor no matter how good and well-calibrated it is. The scopes always rule. 

I hope this helps clear things up.

If you RGB histogram that shows three separate RGB histograms for R G and B and also Waveform and Color Parade that makes ton of difference, as for Vecroscope, i am not even sure what it does.

And still, I get monthly e-mails about people replying here that they want it. 
Speaking as part of "everyone else" - we do. 

AMEN AND PLEASE!!!! ASAP!!!

Hey, so only workaround for real time scopes I've found is with OBS.

I had an idea to just create a virtual screen with only the image you are editing in it and to somehow incorporate scopes into this, thats when I found scopes for OBS. Work fine if scopes are something you love to use as I do.

Just read the read me file, very simple and crop the screen to only the working image frrom lightroom to OBS. Maybe not the cleanes and neates scopes, but they do the job right now.

If it's possible to screen capture to premier maybe that's also a viable option.

You can find the scopes for OBS in this post.

I have to vote for a vectorscope or, at least some sort of simplified vectorscope that shows the fleshtone vector. I've been reading scopes since the 70s (and shooting photos professionally since the same era) and I never could glean as much info from a histogram. That one vector shows where a fleshtone is and anything more than a couple of degrees variation will look off to the viewer. I still can't get as much information out of a histogram as easily as I can out of a parade on a waveform monitor. 

I calibrate my displays carefully, but over 40 years invideo has taught me never to trust my monitors. They are only really useful for shot-to-shot matching, which is more important in multicamera production and editing. The real, accurate signal information can only be found on scopes.

Please Adobe (or some cool indie developer) please add this feature to Lightroom and Photoshop!!!

If what they learn is silly and wrong: teach them! 

Same with this “feature request” that only has 91 votes since 2015. Change takes work. 

As for Out of Gamut warnings that are OT, buggy and unnecessary and there is video to learn that too:

The Out Of Gamut Overlay in Photoshop and Lightroom

In this 25 minute video, I'll cover everything you need to know about the Out Of Gamut (OOG) overlay in Photoshop and Lightroom. You'll see why, with a rare exception, you can ignore this very old feature and still deal with out of gamut colors using modern color management tools.

Oh, I'm aware. But as the video points out, there are people who just use RGB/CMYK because that's what they learned. Actually using CMYK is basically pointless these days, however using an out-of-gamut CMYK check is still required. But that's an entirely different discussion.

Anyway, vector scopes are LAB. Incredibly useful for skin tones and seeing color shift. RGB parade is incredibly useful for white balance and understanding more distribution of your value than a histogram tells you. 

For instance, if you have a picture of someone on a stage in a spotlight, the histogram will have a nice full bell-curved-like value even though the majority of the image is incredibly dark. The RGB parade will show you the distribution of value for the rest of the image....for the most part. It's really just showing all of the values in Y separated by X. So for those that don't know, it gives you something very similar to a histogram, but flattened to a single line of vertical pixels for every column of pixels. 

It is simply, differently useful. Some will find it more or less useful, but still useful.
