Feature Request: RGB Histograms / Tone Curves

Hi team,
It would be really helpful to be able to view the RGB Histograms separately in addition to a composite (rather than the "compact" mode we have now).
It would also be really helpful to be able to adjust the Tone Curve applied to an individual RGB channel in Develop.
Finally, it would be most helpful to be able to see the RGB values as well as or instead of the RGB percentages when moving the cursor over an image area. This would be particularly helpful for fine-tuning skin tones.
Thanks, and keep up the great work.
We're delighted you're evolving Lightroom!
Cheers,
Matthew

Your post seems to assume that Lightroom is a tool for travel/landscape photography, and other types of photography (e.g., portrait/fashion) should be supported by a "specialized add-on module". I have to disagree with you on that point. Considering many of the examples on the Lightroom marketing are fashion shoots, I would think that they considers portrait/fashion photographers to be an important part of their target audience. They are not a fringe group of specialists.
I'm sure that portrait/fashion photographers would feel the same way about a Lightroom capability that primarily benefits the workflow of a travel/landscape photographer, i.e., when I do do some landscape work, I just edit in Photoshop. But you wouldn't agree to that, would you?
Skin tone measurement can be an incredibly easy tool to implement. It can be something as simple as showing the CMY values alongside the RGB values during a mouseover. Keep in mind, I'm talking about CMY not CMYK, so there should be no need to worry about what ICC profile to use. RGB to CMY is a straightforward transformation. It's embarassingly simple.
There are other ways Adobe can implement skin tone management that would be more powerful but a little more complicated. Those would be great too.
Anyway, thanks for the link to the Adobe feature request page! I will use it.
Regards,
Mike

ACR Feature request: RAW Histogram

Hello,
I'd like to suggest a new feature for Camera Raw plugin: the ability to switch between "standard" and RAW histogram (which covers the full data range present in RAW file).
Thank you.

If you mean a histogram in terms of the 12-bit or 14-bit or whatever-bit binary numbers for each of the sensor’s photosites without any camera profile or working colorspace applied, then it would always be very skewed left and, in my opinion, relatively useless.
I don't agree. Raw histograms are quite useful, and I frequently use the freeware program, Rawnalyze to check my raw files for channel clipping. The green channel usually clips first, but clipping in the red and blue channel may take place in the raw file or with white balance. The appearance of the x-axis of the histogram is determined by the scaling, and log base 2 scaling is useful since it related to f/stops.
Here is the raw histogram as shown by Rawnalyze. There is no white balance or demosaicing.
One can also convert the raw file in DCRaw or Iris without white balance or gamma encoding and look at the histogram. I used Histogrammar to se the linear histogram and the log histogram.
One can get a good idea of the status of the raw file histogram after white balance and gamma encoding with ACR by setting the controls to linear (sliders on the main tab all set to zero and the tone curve set to linear). It is necessary to adjust for the baseline exposure offset. For the Nikon D3, the value is +0.5 EV, so the image may apper overexposed without this correction.

I've just bought lightroom and downloaded it and in the Develop Mode I am unable to find the 'Basic' tab. All that shows (in the order that they appear on my screen) are Histogram, Tone Curve, HSL/Color/BW, Split Toning, Detail, Lens Correction, Effects a

My Basic Tab has vanished...clues on where I can find it. I have a horrible feeling I've pressed some 'hide' button by mistake and can't find how to undo it

Right-click on one of the tabs that are visible and select "Basic" from the menu that's presented, Mohammed.

Tone curve RGB histogram visibility

Hi all.
I installed lightroom 4 Beta this afternoon and quite liked the addition of the individual RGB colours adjustable in the improved Tone Curve interface (Develope module), but feel the actual histogram colours of Red, Green and Blue are barely visible. Can you guys at Adobe improve this please?
Thanks,
Kevin.

I'd like to add that this is the Mac version, but I doubt it really matters :-)

Tone Curve Channel Histograms

Just a small piece of feedback - the new tone curve individual channels are great, but the histogram in the background of the curve is very difficult to see. Any chance you would consider increasing the opacity of the red, green and blue? The RGB is more visable.
Many thanks.

This is a very valid point and would make a great feature request. You should consider submitting it through the official channels (no pun intended) http://feedback.photoshop.com/photoshop_family/products/photoshop_family_photoshop_lightro om put your idea here and I will vote for it.

Camera Raw - Enable RGB Tone Curves

In Camera Raw, the Tone Curve Channel selection is disabled. How can I enable it to allow me to adjust specific colors in Camera Raw?
I’m using Photoshop CS5, Camera Raw version 6.7.0.339 on a Windows Vista 64 bit system, and my camera is a Nikon D90.
Thanks,
Jack

I don't think you can...ACR 6.7 was a crossover version tho have compatibility with LR 4 when it was released, as a result it was set to allow processing of certain features that were in LR 4 (and ACR 7). While the RGB curves show up dimmed, I don't think ACR 6.7 allows actually adjusting the RGB curves. I think the only way to get them is update to CS6 and ACR 7.x.

New RGB Tone Curve also a Basic Levels Adjustment?

Adobe Staff: at first I was pleased and then let down about the new RGB Tone Curve feature because I thought it allowed for Levels Addustments - as with so many other photo editing software including Adobe PS Elements where you can squeeze in the left and right triangles to ajust the blacks and highlights and midtones.
I was playing with the Lr4b RGB curve yesterday and - is it correct that it does essentially act the same as "Levels Adjustment" by squeezing inwards the blacks (lower left) and whites (upper right) points?
Thank-you

Yeah, but blacks and whites in the basic panel are better, and usually should be applied after you've appled the others.

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.

RGB Channel unavailable in Camera Raw under point in the Tones Curve

How can I use the the RGB channel in Camera Raw under Tone Curve?

Hi yariel83,
Make sure under the Camera Calibration tab that the Process is set to 2012.

Does the Tone Curve operate in RGB or Lab?

I was wondering if the Tone Curve of LR works in the RGB color space, or if it is designed to only affect the L component of Lab.

Been fighting with some images recently, getting yellow faces when increasing contrast (curves or slider).

Tone Curve RGB does not show up

I am using Windows 64 bit and there is no RGB choice on the tone curve.

Have to be in point curve mode and have to be in PV2012.

I was processing pictures and the Basic function on the right has disapeared ( the one that has Exposure etc) I know see the Histogram, then Tone Curve, HSL/Color/B

I was processing pictures and the Basic function on the right has disappeared, the one that contains Exposure, Contrast etc. I now have only the Histogram, Paint Brush etc, then it goes to Tone Curve, HSL/Color/B&W and all others down to Camera Calibration. How can I recuperate Basic ?? Thanks for your help

i have now found where the OS permission is located but cannot find a way to change it. Here is what I have done:
- Selected the Local Disk Folder
- Chose File>Get Info
- Click on Sharing and Permissions (It shows Read Only)

I can't choose a user or group under the name column, all I have in the Name column is "Local Disk"
Can someone help me from here to convert to Read & Write, thanks
