Lightroom 4 color sampling tool?

It would be nice to have a colour sampler in Lightroom 4 to be able to monitor the use of the new RGB channels in the curve. Is there such an item, or is it possible to have something like that in the toolbox? Something like the Camera raw where you can select mulitple points - or use a modify key to change the eye dropper(Lightroom) into a colour sampler point?

Unexpected behavior with Color Sampler Tool

Hi,
I have a small AppleScript that used the Color Sampler Tool to place two color samples on an image. I am able to read back the (r,g,b) color values for these color samples, but the results in the script do not always match the info windows. It looks like Sample Size is always Point Sample when I read back the values in the script, even if the Sample Size is currently set to something like 11 x 11 Average.
I am running Photoshop CS3 Extended on a MacBook Pro. A copy of my script is attached to this post.
Does anyone know of a way to get the script to return the values using specific sample size settings?
Thank you
-- Bennett

Wow, that's too bad. Does anyone have a suggestion on how I can do the following then?
A. Determine what the current sample size is in the toolbar.
B. Compute the correct average values using a combination of the position information from the Color Sample and the sample size from A.
By the way, my eventual goal is to build this functionality into an Automation plug-in, so if you have ideas that are not possible in AppleScript but would work in C/C++ I would be interested in learning about those as well.
Thanks for your help.
Cheers

Color Matching using Color Sampler Tool?

Let's say I want to replace a sky in a landscape with a more interesting one with clouds. Is there a way to match the luminosity and hue of the replacement sky to the original landscape by using the color sampler tool? That is, to do the color matching by the number rather than by experimenting with various adjustment layers to get the match? Thanks!!

Perhaps you could put the new sky on top with luminosity blend mode. The color of the old sky would show through. But this would invariably require brushing.
Replace Color is a better option. In the dialog, set the source color (in sky with clouds) at the top. Destination color (sky without clouds) at the bottom.
Unfortunately this adjustment is not available as an adjustment layer. You'll want to keep the original image, perhaps as an underlying layer, in case you need to go back to it.

"color sampler tool" equivalent in color?

Hi,
Is there an equivalent to the 'color sampler tool' found in Photoshop in Color? I'm looking for a way to sample a pixel or small group of pixels (maybe a 5x5 square?) in a given frame and get numerical RGB data for that sample, but cant seem to find a tool in Color. Does a feature like this exist in Color (and if not, is there a workaround that would give me similar information)?
thanks in advance!

You can't get an "integrated" medially-dimensioned RGB value picker, but there are three single-pixel samplers available in the RGB scope display. They are explained in the manual as to use, etc.
These numbers are useless in 999,999 out of a million cases. COLOR is not Photoshop, and I don't know many colorists who paint by numbers. "Many" being the numeral "zero". Why, is because there is no "match" tool, and there is no method for directly entering values... only offsets, which is going to be a "poke it and see" kind of process. The only useful application for a COLOR pixel scrub is within Secondaries, which will place a cursor on the HSL curve adjustment windows, so that operator's aren't just stabbing wildly at that adjustment...

Brush is constrained to 90º and appears as Color Sampler Tool

I'm having a suprise difficulty with my brush tool in that its cursor appears as the color sampler icon and it is constrained to 90 or 180 degree painting (sometimes just 90). Everything was working normally with my last use a day or so ago.
Other facts:
I've downloaded the latest update
Caps lock is not on.
I'm unable to right click in the options bar and reset all tools
I'd appreciate any help available. Thanks!

Apple released the 10.6.7 update for OS X today. This update corrects an issue introduced in the 10.6.5 update that affected modifier keys while using Photoshop.
More details, including how to install the update, are available in this Knowledge Base document:Alert "Delete the Adobe Photoshop Settings file?" | Tools, functions behave strangely | Photoshop CS5 | Mac OS 10.6.5, 10.6.6

Color Sampler Tool bug?

Am I nuts here, or is this something with my particular machine? I'm running Photoshop CS4 (11.0.1) and I'm seeing the following:
Create a new image.
Add a folder.
Add a mask to that folder (I've done this with a raster mask, not a vector)
Create an adjustment layer inside that folder (I've tried this with curves, hue/sat, and/or channel mixer).
Duplicate the folder, and invert the mask on the copy.
Highlight an adjustment layer (either one).
Put out a color sampler inside the area masked by the current folder/adjustment layer. This becomes sampler #1. This shows the current values (correctly).
Put out a color sampler OUTSIDE the area masked by the current folder/adjustment layer. This becomes sampler #2. This shows no values (correctly).
Highlight the adjustment layer in the second masked folder.
Both samplers now show no value (incorrect).
Delete sampler #1. The new #1 now shows the current values (correct).
Recreate the other sampler (now at #2). Sampler #2 does not show color values (correct).
Highlight the first adjustment layer again.
Both samplers now show no value (incorrect).
It appears that *all* color samplers are either using the masked area of sampler #1, or combining the masked area of all lower numbered samplers, to determine if they should calculate values. The workaround is to remove all samplers every time you switch masked folders (which can get a bit insane if you have a lot of masked folders). This is not the way it worked in CS3.
Can anyone else duplicate this issue? Or is this unique to my machine? I'm running a fresh install (less than a week old) on Mac OS X 10.5.8, and I've updated to PS 11.0.1.

Added version information

Simply put: Color Samplers will report no information with a Color Adjustment layer selected if it is contained in a masked Group and if the #1 Color Sampler is in the masked region.
The cursor sampler WILL work however. Unfortunately, I often need the mouse elsewhere while making adjustments.
This makes working in masked groups quite bothersome so any help would be appreciated.

Color sample tool

CS4.
Windows XP
When I put text into my image (name and copyright) the character window (tool bar) does not let me select a color. For exampled I will type my name and year on my picture. Then I select the text, open character tool, select color and then I change the color of my text to something in my picture. For some reason this quit working on my XP system (but works on my Vista system - laptop). Is there a simple fix for this ? I don't want to re-install unless I have to. Any help is greatly appreciated. Thanks.

select the Eyedropper tool and set Sample to All Layers in the Options bar

Photoshop CS3 color sampler info question

I'm adjusting RGB images in CMYK preview mode using custom ICC profiles. In taking a color sample measurement using Color Sampler tool and Info Window, I can have the sample data display in RGB, CMYK or whatever.
Is there a way to get each sample to display both RGB and CMYK numbers side by side?? This would be very helpful when 'correcting by the numbers'.

that's what a figured but thought I should ask anyway. Perhaps it should be added to the feature request list.
Thanks for the confirmation.

Color sample reading funniness?

I am using CS4 and have been using PS since version 1.0. There is one thing about the way CS4 handles color samples that is different than previous version. If I have 3 different adjustment layers and check my color samples, the numbers will change depending which adjustment layer I am on. This doesn't make any sense and makes it harder to adjust color and tone. I am intersted in the final color with all of my adjustment layers combined. If I am trying to match color between files and I have a saturation adjustment layer and a curve adjustment layer above that, and I am keeping an eye on my color samples, if I adjust the saturation layer there is no easy way of seeing exactly what the numbers. While I am on the saturation layer the numbers night be 206,250,77, but then when I click on the curves layer the numbers are 219,251,96. So to really know what the numbers are you need to be on the top most layer. It was never like this before. I know this is normal opporation for CS4, but how are others dealin with this?
Another strange thing I found, and this is just with a particular file, but when I hover the color sample tool about an are I get different numbers under the eye dropper info and I do under my color sample point info. The shot is of a pair of jeans, and it's a pretty large file, around 26"x21"@300dpi. I have my eye dropper sample point set to 101. When I first hover the eye dropper abover the area I want to sample the reading in the upper left of the info pallete is 102,120,153 then as soon as I click the color sample point reading is 150,169,204. This was done on just the background layer, no other layer have yet been added. I even tried blurring the area to get rid of any texture, but still the same issue.
Well I just figure out what the issue is but I thought I would post this anyway. I found out if I zoomed into 100% first, then placed the sample point it worked like it is suppose to. I know that viewing both color and sharpness can vary slightly when your not at 100%, but I didn't think that it would effect the actual numbers?

I agree an altarable "Funny Factor" woud be a useful addition for CS5. Maybe a dial of some sort, turn it up and its funny, down and its not so funny.
Look at your eyedropper options there are checkboxes for Sample all layers and "sample size"

Persistent color sampler from cameraraw to XMP

The samplers created inside cameraraw plugin don't stick between cameraraw sessions, loosing the color values read before to compare afterwards.
For example, when I open images on photoshop as smart objects using cameraraw and create color samplers, and I re-edit the smart object layer (using cameraraw again) the samplers aren't there any more.
Some times the new color sampler position isn't same anymore and the reading of the color values change. And that betrays the potential of intelligent objects.
XMP would assume the position and the color values, and that could be even read later from photoshop script to pass it to the same color sample tool (but this would be another potential addition not regarding the problem here).

OK, I may just be having an extraordinarily stupid day, so bear with me..........
The url's in the previous reply don't work any more - I presume this is because the forums have been reorganized?
But, beyond that - here's what I RECALL doing in the past.......................
In my image, create a color sampler point using the color sampler tool.
Create curve adjustment layer and make that layer the current layer.
Go back to my image and press ctrl+shift and click on the color sample.
This would put the rgb values (puts a point on the curve) from the color sample on the red, green, and blue channels of the curves layer.
After reading the last couple replies, I did the same thing. And I went "back to my image" and clicked on
the color sample. I'm STILL not getting the values on my curve layer......
What am I missing 'cause this can't be as difficult as I'm making it.........?

Is there a feature of the Color Marker Tool missing?

Why won't it sample a color as a variable when placed by an action? Is there a step or feature I'm overlooking?
I've done a bit of due diligence and the only solution I've found is an external script. But considering the function and features of the Marker tool it would seem like that functionality has been overlooked. I say this because if a Marker can be placed by an Action to a specific set of coordinates then it would seem to follow that the characteristics of that location would change from one canvas to the next. As such being able to set the foreground color based on that change would seem to be the key function of the tool.
So what am I missing? If I'm not missing something it would seem like Adobe should be able to provide a patch promptly and without fanfare.

Sure the Color Sampler Tool except that it doesn't actually sample it just describes the color characteristics of a specific location.
Having the tool should also have Action functions of it's features as the default since the other way to get a useable color sample is to use the color sampler tool (or eyedropper) The script should just be embedded in the Marker and executed when the Marker is used as an Action step.
Creating the tool at all would seem to have the Action functionality as a requisite. Otherwise it's just another Eyedropper that happens to know where it is in the canvas. Useful at times but a bit frivolous.
I like to do a bit of research before I submit feature requests but I might do that, and thanks for reading.

Problem with Color Sampler Points

I'm using PSCS4 on a Mac Pro, and recently upgraded to Snow Leopard 10.6.3 from Leopard 10.5.8.
I regularly use color sampler points in Photoshop when adjusting curves. I seem to be having problems getting a sampler point to show up in the info palette when shift-clicking with the eye-dropper tool, or directly using the color sampler tool. I've also tried shift-clicking from within the Threshold command, but the points I click just don't seem to take a sample and show up. I never had this problem before. I'm bringing RAW, sRGB and ARGB digital images into PS from Bridge, and have tried 8 and 16 bit.
After trying for awhile, sometimes it just suddenly starts working again. For instance, I was writing this post after not being able to get PS to take samples. Then I went back and forth between the internet and PS, and it started working all of a sudden. Very odd.
Anyone else seeing this? Am I doing something wrong? Any workarounds?
Thanks, Lou

Thanks, Mark. You may be right, and I will try it.
I have my workspace setup saved, but I presume it is lumped in with all the other preferences. Is there a way to "Export" my saved workspace setup from Photoshop, so after I trash my preferences, I can reimport at least my workspace? I didn't see the ability to do that, but it may be hiding somewhere. I like my current dual monitor setup and prefer not to have to 'redo' it from scratch.
Thanks,
Lou

Color Sample

Hi,
How can I remove color sample points in Photoshop CC. Didn't there used to be a clear button on the toolbar of the eyedropper tool?

The Clear button is visible when the Color Sampler Tool is selected.

Color sampler onto curve layer?

I believe I knew how to do this but the brain cell that had the information must have died......
I BELIEVE I used to take the color sampler and put a sample on my image. Then I created a curves layer. AND, by holding some combination of shift/ctrl/alt and clicking the color sample, the values would transfer to the red,green, and blue layers of my curves layer. From there I could make adjustments...
In CS4 I'm trying to do this, and I can't get it to work... It isn't the same as using the eyedroppers on the curve OR the hand above the eyedroppers. It actually copied the color sample values onto the individual color channels..... How do I do this in CS4?

OK, I may just be having an extraordinarily stupid day, so bear with me..........
