Lightroom :: Tone Curve - How To Adjust Individual RGB Channels
Jun 2, 2012
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.
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?
I am learning about using channels as a mean of channel masking in CS5. The instructor on a dvd starts with a general understanding of channels. Within the first 2 minutes, I can't seem to replicate his instructions.
Here are steps I take to look at the individual channels Red, Green, Blue.I invoke "Channels" in my layers palette. What appears is the RGB, Red, Green, Blue Channels (with the eyeball showing in each of the individual channels).The instructor says to click on each of the channel and you will see the appropriate a tone map of each individual channels.
When I click on lets say the red channel, nothing happens ... all of the layer eyeballs are still on and I get no individual tone map. If I deselect all of the eyeballs, then I can get the individual channel tone maps.
I suppose that the instructor is using a shortcut key to invoke each individual channel tone map, but he doesn't explain it.how to get an individual tone map directly after opening up the channels palette, without having to manually remove each eyeball.
Why in LR4 is the Tone Curve default set to Custom with a contrast lowering curve? I would like the default to be linear, but I can't remember how I set that up in LR3.
Why does the clarity slider seem different to me in LR4 (4.1 RC actually)? IN LR3 I loved that thing. I would ramp it up quite a bit with many photos. It would give it a nice crisp look. Now it seems as if it just makes my shots look like they have too much contrast. Also, when using the clarity brush, many times it seems as if where I paint it on it actually lightens it up. I havce had to look as see if I had the exposure tool on instead.
Also, I swear a "medium contrast" tone curve setting is different now as well. This was the default setting in LR3. Now default is linear. But if I apply a medium curve from the drop down, it looks over cooked? What the heck? Are these things just me? BTW I am working RAW files.
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.
When I go into Lightroom 5 Develop mode, the Tone & Point Curve box has disappeared. It was there yesterday and I can't figure out how to get them back. I just purchased the product 2 days ago.
Installed LR4 today and ran into a problem.I have been working with alot of negatives lately and therefore my photos have a reversed tone curve. When I converted my existing catalog all looked fine, using the old previews. But when I go into develop on any of the photos the tone cureve gets reset to normal behaivour, and I have to redo the "invert". And all this using the old process (2010).
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
Currently I'm trying to save an own "tone curve" but in the menu no entry to save it appears. In my understanding an entry "Eigene" (or "Own") should appear as soon as I am changing the tone curve manualy.
I am using the latest version of Lightroom 3.6 running under Windows 7 64-bit (both in German) with Camera RAW 6.7 installed.
I created a custom Tone Curve in LR3.6 on Win7 64-bit as an XMP file, changing the default location to another folder. I right click on the Custom <> icon and can see the Save feature and some preset curves, but not the Tone Curve I saved that I called "Backlit Tone Curve.xmp." Do I have to move it to a special folder in the presets directory? I restarted LR and it still did not show up anywhere.
I need to know how to save an individual color channel. I am able to split the channels, but they are in gray and not color. How would I save them in color? My PS is CS5.
I'm working on a RGB file and I accidentally hit 'Ctrl 3' which brought up the blue channel - I really liked the image in that channel and I was wondering if it was possible to print it - as it's black and white it looks quite moody and interesting..
I've been trying to change the brightness/contrast of a single channel (red channel, etc.), but it always applies to all of them, even if I select only one of them. I havn't been able to find and option which will allow me to work with them individually.
I have recenty had to reinstall all my software, and manged to find most of my old Lightroom settings in the Lightroom Presets folder (inside the Appdata folder on a PC) but I seem to have lost my custom tone curves.
Do you know which folder they should be in (indise the Lightroom Presets folder)
I STILL don't understand why there are TWO comminty forums for Lightroom;
I was wondering if there was an easy way to view individual color channels (Red, Green, Blue) in the viewer, and if so what the shortcuts are. I know you can do this simply in flame but can't seem to find a way to do it in Smoke.
Clone tool has never acted like the demos show it too. This is how it has worked in CS3, 4, 5. I see all the demos that show it working as I would think it should. In reality all I have ever gotten is cloned items which are visually close but are always lighter or darker.
That is light items clone even lighter, about an f stop worth and dark items clone even darker about 1.5 f stops it seems. In fact it will clone white and black just fine but is really almost impossible to get accuate work around neutrals such as skin. After months of various reading and tonight alone I have spent 5 hours of settings and variations trying to get accurate work to no avail. Am I using the wrong tool?
I find I can get accurate clone if I select an area, Control J a layer and then move it and put it in w/ healing or such as necessary. Why must clone adjust things?
Why is it that when in Draw save the tone curve settings it saves in a totally different directory? Then if I want to open that settings file it takes me somewhere else showing default styles/settings (*.crv)?
I have a long animation. I want to use populate at frame 12000. But populate frames won't let me go over 10000 frames. How can I get my people to animate after frame 10000 as you cant adjust the start point in the curve editor.
What are they used for? I have been using PS for around 3 years primarly for web design and I have never used channels outside of loading a selection. I searched for more info; I mostly got tutorials that use alpha channels, but no real explanation as to what they primarly do.
I'm trying to work out the optimal workflow for doing HDR (using HDR EFEX 2) on a set of images. I can apply LR's Lens Correction (Nikon, 17-55mm F2,8) and chromatic aberation removal on the whole set set (using LR Sync) before I export to HDR - then turn off the Chromatic Aberation fix in HDR - and that gives me one workflow.
However, that makes a lot of changes to the TIF's before I go in - so I am wondering if it would be better to export the RAW files converted to TIF using minimal changes from LR e,g, no CA fix or Lens Profile correction; let the HDR do its thing and then make profile corrections, Upright, etc upon return from HDR. However, when I get back from HDR and go into Develop with the returned file and go to Lens Correction, I cannot chose the 17-55mm F2.8 lens from the drop downs. There are only about 4 or 5 lenses now showing as Nikon possibilities-and the 17-55 is NOT among them.
How come I don't still see the full list of Nikon profiles - shoudln't I be able to apply any profile to a TIF (even an incorrect one) ?
I tried pasting the Develop Settings from a virtual copy where I had set the Lens Profile to 17-55 F2.8 - but that only turns on the Lens Profile 'filter' and does not actually force-on the specific correction.
why Lightroom 4 is importing my images with a warmer tone, then exporting with a cooler tone. There are no presets selected on import so why is it doing this??
Why would Lightroom give a sepia tone to anything I am working on? This only happens if I am using my AOC 27" monitor. The menus are still white, only the work gets the sepia added. Now the strainge part, if I switch to a different monitor, the problem goes away. I also use Photoshop and have no problem.
I imported tiff images into Lightroom 4 that were scanned by DigMyPics.com. The color of the images look good on the Windows 7 photo viewer. It looks horrible in Lightroom 4. My monitor is callibrated, the import develop setting is set to "none" , the box is unchecked "apply auto tone adjustments".I think that the windows viewer is showing the accurate color of the scan and LR is not. I don't think DigMyPics would send this awful color.
i have scanned 35mm B&W negs into LR4. have printed about 40 images. all have different tones. some have blue or green or brown tones. some images are warmer than others and some colder.
the temp and tint scale are grayed out. impossible to have all images with same exp/contrast/etc.i have been told that when presenting a b&w body of work, all printed images have to have a similar tone.
Having just loaded 10,000+ scanned negatives in LR 4.3, I am applying Auto Tone as a starting point for development settings. I have selected all images in Grid View, right-clicked to Develop Settings...Auto Tone. I can then go to the Develop page and Auto Tone is shown in every images History.the Auto button is still visible and I can click on it and get different [generally better] settings.
Is there a reason why Auto Tone applied to multiple photos produces different development settings from when it is applied individually to each photo?
There is an apply auto tone adjustments checkbox in preferences, but it does not work properly. After checking it, some photos still require to click on auto button on the basic panel.
