Tone curve panel

New to LR and have just discovered I should be able to see a 'tone curve panel' in Develope mode. There is no such panel available
on my screen - what am I missing?
LR v 2.3

Right-click on the panel on the right side of the screen in the develop module and make sure that Tone Curve is checked on the list.

I have lost my "Basic" panel in the Develop module and can't figure out how to get it back. My right panel goes from the Histogram straight to the Tone Curve panel. My Basic panel should be below the Histogram. Any ideas how to get it back. I have even uninstalled my lightroom and reinstalled it with same issue. Help!!!

Right click on or near one of the other headers and a pop-up will appear and you will be able to select the Basic Panel for viewing.

Missing Basic and Tone Curve Panel in LR5

Last night I installed LR5 (last version was LR3) on my iMac with Mavericks OS and everything was working fine, I thought, and I was using the Develop Module when I noticed the Basic Panel and Tone Curve Panel (which I had been using) had gone missing . As in, poof, they were gone. So now I have the Histogram, the Crop and other tools and brushes, and then nothing until HSL/Color/B&W and then on down.

I'm cheating here with another question, but I think it will be quick: I see LR5 automatically uses the updated interface for Highlights, Shadows, Blacks, Whites and I see they are more precise and subtle. Can I go to photos adjusted in LR3 that still show the LR3 interface and use the LR5 interface & finer adjustments on the old photos?

LR5 not showing Tone Curve "region" panel and associated sliders.

Hi,
The Tone Curve panel in LR5 as currently set up isn't showing the "Region" sub-panel and associated sliders. It also isn't showing the slider immediately under the tone curve itself. Any ideas on how to get these features to show?
Thanks

Hi Jao,
Bingo! That did the trick. Many thanks.

LR4.1 - Tone Curve - how to adjust individual RGB channels?

Hi,
I am having trouble figuring out how to adjust the curve of individual RGB channels. I am assuming the LR4 Tone Curve works like the PS Curves dialog with the channel dropdown.
The LR4.1 Help says:
To make adjustments to individual points on the tone curve, choose an option from the Point Curve menu, click the Edit Point Curve button , and do any of the following:
Choose an option from the Channel pop-up menu. You can edit all three channels at once, or choose to edit the Red, Green, or Blue channel individually.
When I click the little icon in the lower right corner of the Tone Curve panel, the panel shrinks so that I don't see the Regions sliders. If I click again, they are visible again. I can't find where to select one of the three indvidual channels.
The Help refers to "the Point Curve menu." Where is the Point Curve menu? Is the Point Curve different from the Tone Curve?
If I right-click (Windows) in the curve dialog, the context menu has a Show Info option. I click it on/off and don't see any change or any info. Where should I be looking for info?
Thanks for any help here.
John

Good morning John,
The point curve is the one without the sliders. The adjustments for the individual channels are only available with
PV2012. You must be editing a file with PV2010 or 2003. When in PV2012 you will see " Channels: RGB" below the curve window. Click on the doule triangles following the RGB
to pick the individual channel.

New RGB tone curve is absent in my LR4 upgrade. How do I get it to emerge?

help please

Click on the little curve icon at the bottom right-hand corner of teh Tone Curve panel. See screenshot:

LR5 Cannot find any Channel Pop up menu in Tone Curve?

Am reading Kelby's LR 5 book page 162 +
Cannot see any place where I can click to see the individual channels adjustment pop up to select chanel. He even has it circled in the illustration but I don't have anything like that in the Tone Curve panel
What am I missing, I'm in Win 64K
Thanks in advance for any help

if your tone curve panel looks like this than click the little box with the curve in it in the bottom righthand corner.
Then it should look like this

Missing Tone Curve Sliders

Hi all,
I'm not sure when this happened, but I just noticed that the Tone Curve no longer has sliders to adjust Darks, Lights, Shadows, etc. All I have is the curve itself and the dropdown to adjust the type of curve. Did I accidentally change a setting that hides the sliders? I'm running LR 3.3 on Mac. Thanks in advance!

Paul,
There's a non-obvious button in the lower right cornter of the tone curve panel. It looks like a diagonal line with a dot on it. Press it.

Tone curve "region" disappeared

hello,
i am running lightroom 3 on mac os 10.6.8. i use lightroom constantly and have never had any problems. i started lightroom today and went to the develop module only to discover that under the "tone curve" panel, i no longer have any sliders for highlights, lights, darks, and shadows. the graph portion of of the panel is there, containing the actual tone-curve, but everything else is missing. anyone have any ideas on this? screen grab of the panel is below.
thanks!

Click on the small curve icon in the bottom right hand corner of the Curve panel (you can see it in your screenshot) and the curve will change back to sliders.
The curve that your screenshot shows has actually one big advantage over the other: You can drag the end points of the curve vertically up / down to set your black point or white point.
For instance you drag the bottom left point of the curve vertically up until it shows about 5%. And correspondingly you drag down on the right top end to about 95%. That ensures that you have detail in the highlights and in the shadows.

Tone Curve sliders missing?

I have LR 3.2 and today I noticed that the region sliders in the tone curve panel are gone.
Has anyone else experienced this?

Thanks Rich.,
That did it.

DNG PE: I want to try other Tone Curve but ...

In DNG PE I load a dng file, I choose a camera profile, I go in the Tone Curve panel in the Base Tone Curve I set Linear, I click on the curve and I set in 95 out 160 (only one point for this purpose) and then I save the new profile.
I go in ACR, I load an image and I switch to new camera profile: the image become very light.
I launch the DNG PE, load the previus created camera profile, click on Show Tone Base Curve: the showed curve is not parent with that I created (95 in 185 out, see below in black what I have created, in red what the profile has registered)

Hi Marco,
This is mostly (*) possible, but not directly via the DNG PE. The issue is the encoding space. Your RGB tone curve that you describe above is defined in a gamma 1.8 space (since ProPhoto has a gamma encoding of 1.8 ). The (black) tone curve interface in DNG PE is defined in a gamma 2.2 space.
In other words, if x is a linear signal and x' is the transformed linear signal, then the math for the former case is effectively
x' = x ^ 1/1.8
x' = ApplyToneCurve (x')
x' = x ^ 1.8
whereas the math for the latter case is the same except for the use of 2.2 instead of 1.8.
You will need to perform the appropriate transformation so that your 1.8-relative tone curve is expressed properly in a 2.2 space.
Once you have the actual numeric curve worked out, one way to make the required tone curve is to edit the .dcpr (recipe) file from the DNG PE using a text editor.
(*) The reason I say "mostly" is because another detail is that the PS RGB tone curve is a 1D curve applied separately to each channel. This is not the way the tone curve works in Camera Raw.

Tone curve RGB

I am trying to alter individual RGB channels within the tone curve box, but I don't get a pop up dialoge box. I saw a mention of PV 2010 and PV 2003, but I don't know what these are, or if one can convert to them.

Look in the camera calibration panel and it will tell you. Alternatively, if you're seeing the current set of sliders in the basic panel (e.g. highlights, shadows, etc.) then that would confirm you're using PV2012.
Go to tone curve, click on the little curves button at the bottom, and you'll be in point curve mode. Click on the RGB button to choose a colour channel.
As you're on the web, I recommend searching for "process version Lightroom" to find out more about that side of things.

Tone Curve in Profile Help

Hey all,
Hoping the more talented tech gurus can help me out a bit here?
I have custom camera profiles for each of my cameras, so that my colour is consistent across bodies. They're all dual illuminant, some made in the old DNG profile editor, more recent ones in the Lightroom plug in from Xrite (Passport).
The colour is excellent, but I always find the tone to be too contrasty for my preference. When I look at the values on the step chart (greyscale patches) part of the McBeth checker they are not uniform / linear but rather already hold a contrast adding tone curve. What I do in Lightroom is to take the TAT tool in the curves panel and move these points per patch until they are almost "linear" again. In effect I apply a custom inverse S or reverse S to the image. I then save this curve per camera and invoke it on import setting along with the colour profile. I LOVE, LOVE the files I now get with this calibration, skin tones especially.
BUT
I now have my curve area of Lightroom being used essentially for calibration purposes, which robs me of it's use for creative purposes. Thus, I'd like to do this tonal adjustment at the profile stage, in the .dcp file to free me up to use the curve panel to suit my artistic vision.
SO
The question is how do I visually target the tone curve in DNG Editor (or passport) to match those which I have created in the curve panel now? I can eyeball it so they look similar, but it's a bit vague. Either that or a way to visually adjust the tone curve while viewing the grey swatches within the DNG editor?
The result should be the same as my custom camera profile plus my bespoke lightroom tone curve but all done in the .DCP file.
Am I missing something? Willing to be schooled always!
Many thanks if you made it this far.
(Note: I have posted this in LuLa too, so apologies to those who may frequent both)

New User need help... can't make any adjustments othe then presets and Tone Curve

Please Advise
Thanks

Not sure what you mean, but maybe you can try right-clicking on the Tone Curve (or other panel) heading and then check the other panels you want visible. In other words, in the Develop module, right-click next to the words "Tone Curve." Is that what you are after?
Edit: Or.... try the Window Menu and then click Panels and make sure the right panel is showing.

Brush mode: Tone curve, etc

Well, I'm new for LR, I'm trying to tweak a certain part in the photo by using Tone curve and else, but I don't think the LR would allow me to do that in the "Brush Mode", am I correct?
Because, I need to change some parts in the photo by increasing only red or green or blue, or even highlight and shadow, but I can't do that like Aperture in Mac. Or I do miss any feature control panel in the LR?
Seem like the LR would not give flexibility when working in Brush Mode, is this correct?

I understand.
When I first tried Lightroom (1.4), I was a bit disappointed with the scope of the develop tools available (and did not buy it). When Lightroom 2 included Clarity and Locals it was a big improvement (and I bought it and started using it along with Nx2 & DxO & Photoshop), but it still seemed lean compared to some raw converters (Nx2 as example). I mean, what Lightroom does it does well, for the most part, but full-featured develop tools can not really be touted...
Lr3 is known as the release when Lightroom became a true professional-grade development tool in my opinion: image quality + lens corrections. I applaud Adobe's decision to do just that. No more front-ending with DxO or Nx2 or DPP or CaptureOnePro, or Photoshop + Noise Ninja... I love Lr3 .
Still, I'm hoping Lr4 is known as the release when Lightroom comes of age, develop-module-wise... (distraction removal, more locals, signature auto-masking technology, better color adjustment including rgb curves, ..., and of course fixing of highlight recovery). No more doing without or frequently processing with a pixel editor after basic adjustments in Lightroom... If they do this, I will really-really love Lr4 .
Then in Lr5, Faces & Places & GPS & Collages & HDR & Layers & DLNA Servers & Networked Catalogs, or whatever... - I wont care... (yeah right .
