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.

Tone Curve Sliders Disappeared

My tone curve sliders disappeared in Lightroom 3 (exposure, recovery, fill light, blacks, brightness, saturation, vibrance). I have googled it and tried a few things with no luck. THanks in advance for your help! I am desperate to resolve this ASAP!

I just realized i was not missing my tone curve sliders. i was missing the basic panel. i restored it by going to Help--Search--Basic Panel and it popped up. RELIEF!

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 adjustments Missing

The tone curve adjustments are missing in my copy of lightroom 3
That section of the develop tools resided near the top of the right hand panel.until about 1/2 hour ago. Its now missing
What has happened?

The graph and sliders are not displaying, I can find nothing to check

Individual tone curve sliders have disappeared.

I have the Tone Curve and I can make adjustments just fine. But the three individual sliders beneath it are gone. Tone Curve is checked in Window\Panels. I honestly have no idea what I did to toggle it off. Read a similar thread from 10/20, but the answer didn't solve my problem.

LR5 Develop Module, Tone Curve gone missing.

Hi can anyone suggest how I can get the Tone Curve back. I've done all the usual checks. One day it was there and the next it was gone.
I'm using a MacBook Air. (no problem with LR5 on my MBP)

Did you ctrl-click section header bar, e.g.

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.

Tone Curve Region Sliders ?

Please explain how you can identify an area of an image that could benefit from adjustments using the Tone Curve Region Sliders, and explain how to set the sliders to get the effect you want.
Thank you.

I think that the NAPP Lightroom page has a freely available video that shows how and why to use this part of the tone panel.

Tone curve - please bring back sliders, Canon DPP software just as clumsy!

Please bring back sliders for the tone curve beta 4 in this respect is now just as awkward and clumsy to operate in this respect as Canon DPP!

You can change from parametric to point curve mode yourself with the lower-right icon in the tone curve.

Lost Sliders in Tone Curve Dialogue 3. & 3.2

Windows XP- I cannot retrieve region sliders in Tone Curve in Develop module. Point curve still visible & useable. Can't find any info under communities. Anyone any ideas please? No problen on laptop Win 7 64. What have I done?

Allan,
You clicked on the little square with a line through it in the lower right corner of the Tone Curve control, putting yourself into Point Curve mode. Click it again to go back.

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?

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.

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.

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.

Which do you prefer: Increasing exposure or adjusting the tone curve?

I'd like to know how people here handle their images.
I use a Nikon D7100 in camera RAW. In camera my images are always in balance. In LR, if I select Auto Tone in Basics invariably it will adjust the exposure. I tend to adjust exposure near last in my workflow because I assume my camera had the exposure setting right. When I feel I need to adjust the exposure my first stop is the Tone Curve. I'm wondering a couple of things:
1) I know we edit by the specifics of each photo, but generally do you make adjustments to Exposure or the Tone Curve first?
2) Is there a reason or a time to prefer one over the other?
Thanks,

My recommendation:
(note: I am interpreting "exposure", in your question, to mean "dynamic range at right wall of histogram", i.e. white point)
Adjust basics exposure first (before tone/point curve), but note: you may not be able to go all the way using the exposure slider. Next stop (if necessary): +whites, but note: it may not be optimal to go all the way using whites. Final stop (if necessary): cinch in the the exposure by dragging white point to the left via the point curve.
Rationale: basics have some intelligence and magic that tone curve does not. If you do tone curve first, you've missed some opportunities..
Still a begging question: how much exposure vs. whites vs. tone curve (point curve).
Note: go easy on the contrast at first, and assure blacks are sufficiently seated using blacks slider (and maybe tone/point curve).
Likewise, cranking whites up will increase global contrast, so if you take a shot at blacks and whites before contrast, then you may avoid a common mistake: radically wrong contrast due to adjusting before establishing ballpark black & white slider values.
Anyway, be aware that increased PV2012 exposure (and/or whites) is designed to be used with -highlights (note: there is no "brightness" slider), and to avoid making things too washed out (or over-jamming the highlights) it may be desirable to substitute +whites and/or +shadows for some +exposure.
Note: tones may gang up (on the right side of the histogram) in a non-optimal way when using +exposure and/or +whites, in which case it may be better to use point curve for white point adjustment (e.g. leftward drag). For example, sometimes the whites will be overly compressed if you don't bring white point in on the curve instead.
Rules of thumb:
Most of my normal photos end up with:
+exposure (to fully brighten)
+whites (for full dynamic range without excessive exposure setting)
-highlights (for dialing back +exposure and/or +whites)
+shadows (so -blacks and doesn't leave image with overly dark shadows)
-blacks (for full dynamic range without needing as much contrast)
*contrast: depends - if overly contrasty to begin with (or a lot of -blacks and/or +whites are employed), this usually gets dialed back; if underly contrasty to begin with (or +blacks and/or -whites have been employed), this usually gets bumped up.
(for abnormal photos or when desiring abnormal results - anything goes..).
Other common mistakes (in addition to wrong contrast and/or non-optimal balance between exposure & whites..):
trying to recover highlights via -whites. try -highlights (and maybe +whites) before -whites.
Warning signs:
if you have very high values for +shadows and -highlights, you may have contrast set too high.
if you have a positive value for highlights, you may have contrast/exposure/whites too low.
if you have a negative value for shadows, you may have contrast too low, or blacks/exposure too high.
Miscellaneous:
Try +clarity and +saturation (and/or +vibrance) to pump it up, if reduced contrast and/or increased exposure has left it looking a little washed out.. (likewise, -saturation if +contrast has left it looking a little too "rich"..).
You already know this, but for the sake of completeness (and other readers): you can learn by clicking 'Auto Tone' "button". You may need to dial back the exposure afterward etc. but it can be very educational none-the-less..
Of course, you can always fine-tune tone using tone curve (e.g. if image is just way overbright, like some snow shots, try tugging the midpoint downward..).
Don't forget the locals for final spot toning.
In case you haven't gleaned yet, adjusting via PV2012 is not the same as you might think at first - you don't just set exposure/black/white points and leave them, and then adjust everything else. e.g. -highlights pulls white point down more than -whites does (but +whites brings white point back up, which means you usually need to adjust in tandem..), so be prepared for a lot of back n' forth, to lessen with experience..
PS - There are tutorial videos galore, but at the risk of opposing Adobe and their sycophants, be forewarned: some are geared to how they wished PV2012 was (simple), and not to how it really is (interdependent image-dependent settings..) - examples:
top-down is touted, but that ignores black/white point issues which can lead to radically wrong contrast (and/or exposure) setting.
often, adjustment of blacks is considered optional/fine-tuning, but blacks sometimes need large value adjustment, and dramatically impacts contrast & shadow brightness..
often, adjustment of whites is considered optional/fine-tuning, but sometimes optimal toning can only be had by using a large whites value adjustment, which dramatically impacts contrast, and exposure..

In case not clear yet, adjusting exposure and/or whites (and/or white point on curve) and all the rest is often done to turn an image "with potential" into a very nice image, not just to compensate for in-camera exposure imperfection. I have lots of under-exposed images that end with -exposure (granted, usually +whites), and vice-versas.. That said, if you don't know whether to crank it up or down, there is something to be said for passing until you do..
Lastly, for emphasis: exposure slider is an intelligent slider. It behaves more like normal exposure adjusters at lower values, and more like brightness adjusters at higher values (has clipping protection and highlight roll-off logic which kicks in as you crank it up..). So, it's a mistake to think of adjusting it just to make up for non-optimal camera exposure setting.
Sorry for verbose answer, but there is really no short answer which doesn't run the risk of being bad advice: best way to adjust "exposure" depends...
Cheers,
Rob
