P: Brighten the Histogram as LrC 13.0 histogram is much darker than LrC 12.5

I agree with the other commenters. This histogram is harder to work with and borders on unusable. What I really need to come back are the vertical grid lines on the histogram. I can deal with the dark colors. Without the grid lines, it becomes harder to make adjustments in the right amount and ensure consistency between photos.

I have never commented on any forum like this before, but I've been driven here to contribute my opinion of the new histogram. If this is the first and the last thing I ever say, so be it...

The new histogram is vile. Straight trash. Change it back please.

I have been using histograms in many different photo editing softwares for over a decade and this is the worst histogram I have ever seen. It is repugnant. 

I just arrived home from a two week exploration of a foreign continent with thousands of photographs and I can't overstate the agony I feel having to use this despicable disgrace.

I get it, the design team tried really hard. It's a major flop, sorry guys.

It is seriously that bad. Ban me if you want, but obviously I'm not the only one.

I'd just like to throw these two screenshots in here again to raise the issue that the v13 histogram is ridiculously dark. I'm editing my photos with my monitor at 120nits because I actually print my photos (and don't care about HDR that burns the retina of my eyes).

I really, really can't comprehend how anyone with a sense for ACTUAL PHOTOGRAPHY could come up with a bloody dark histogram rendition like this — and think this this is ripe for a prime time production environment of WORKING PHOTOGRAPHERS.

v13 histogram aka "Prince of Darkness"

v12 histogram aka "wait, users can actually see the distribution of the tones in this clearly — let's kill it"

And that's all...

I've been using V13 since it got released, and until this morning it didn't hit me how unproductive the new histogram is.  Previously, I just shrugged and lumped it in with the "Well, they've gotta change SOMETHING every time, even if it makes a usable tool less useful.  This time it was the histogram"  It's sometimes a bit frustrating that LR has changes that have been requested for years, and ignored, instead spending time on things like this...  Even having been one, I sometimes can't figure out what went through some designer/developer's mind when they decided a change like this was a good idea. 

I would like the histogram gridlines (present in earlier versions) to be brought back. Channel colours should also be presented in a clear/more obvious manner.

Expected functionality: Histogram is shown over a gridline. Channel colours are presented using solid/more obvious colours. (Refer to the image below, ignore the red circles.)

Customization: Additionally, it might be useful to allow users to choose between turning gridlines on or off, or choosing between the older and newer histogram style. 

Benefit: Gridlines allow us to visualise in a clear manner where the channel values are placed, so that we are able to ensure consistency between photos. Having the channel colours be more obvious also makes it more discernible.

IT IS AWFUL!!!!!!!!!

Whether you call it a bug or a feature, this is a problem. I can no longer determine from the histogram if the image contains a value of zero/pure black or real white/255. The green channel, in particular, now ALWAYS displays a full range of tones from one side of the graph to the other, even when the image does not contain values of 0 and 255. This renders the histogram useless as a tool to check and adjust tonal range. I don't care if we go back to the V12 version, I just want the histogram to do its job: to accurately reflect the tonal values of the image. Adobe, please fix this. It's a bad decision.

@jonholcombethe histogram needed updating for the HDR range visualization, but whether the actual rendition had to be this way is a different question of course. 🙂

All, I have now made a new post insisting it is a bug here https://community.adobe.com/t5/lightroom-classic-bugs/fix-lightroom-13-histogram-to-show-free-parts-of-histogram-properly/idi-p/14160873#M47707

That one does not request v12 histogram back but requests for v13 to be fixed to be usable again.

>As this was forced down ACR users and Lr users, I searched those community's for complaints. Nada in ACR, nada in PS, but one possibly related in Lr Ecosystem

You are right - it is the same useless line style in ACR. Photohop however is fine - still has usable histogram.
