Photoshop :: Image With Color Picker To See Pixel Values
Sep 22, 2013
I'm using a Canon 40D, Photoshop 6 and a Mac Mini running OSX 10.8.4.
I'm loading a RAW image from my Camera into Photoshop in 16 bit mode. As I understand it, my Canon 40D has a 12-bit A/D and RAW images have a 12 bit depth out of the camera. Loading them in 8-bit depth would lose some dynamic range/resolution, so I choose to load them in 16 bit mode.
Once the RAW image is in Photoshop in 16 bits, I scroll over parts of the image with the color picker to see the pixel values. This is where I lose understanding of what's going on. The color picker shows pure white values as 32768 and pure black values as zero. Apparently Photoshop (or Camera Raw) is shifting the 12-bit camera data up to fill the top 16 bits in Photoshop. But this is not entirely true! If it truly shifted all 12 camera bits into the 12 MSBs of the 16 bit Photoshop value, wouldn't the max white value be 65535?? If the 12 bits were shifted into the 15th bit, wouldn't the max value be 32767?? Where does 32768 come from? Also, what is Photoshop putting into the LSBs after it does the shifting?
I'm trying to do some averaging of lots of low light exposures using Linear Dodge in 16 bit mode. If photoshop indeed shifts the 12-bit camera values to the MSB of the 16 bit word, I'll eventually run into clipping when I sum my images. I'd have to go to 32-bit mode and that really slows down my system, almost to the point of uselessness.
What's going on in 16-bit mode?

On opening Elements 2, foreground color is white but changes to yellow if a file or image is opened. Checked hexadecimal values and they are the same. Operating system is Windows XP.

I'm running Design and Web Premium CS6 on a Windows 7 machine. I was recently using Ai's Recolor Artwork dialogue for a CMYK document. I wanted to convert my 4 color artwork to Pantone solid coated. I decided to chose some different Pantones. In older versions of Illustrator I could easily open the Color Picker, click on a Pantone value and then just type in a new value to scroll to it. This is no longer the case with Ai CS6.

Feature that would pick the right color on the 1st mouse click when working with images that have many colors and shades etc...Today we need to move the mouse over the pixel and click it to select the color under it and make it active, only then we get the RGB/HSV/Alpha info about it.and if its not the correct pixel info we need to select again. etc...
to make the color selection faster and more accurate on the first click and also enable us to select directly only the pixel with RGB info we want.
It would be great to have online/active display of the Color and RGB/HSV/ALPHA information on the pixel under the color picker , in the toolbar like in the picture i have added.this would make color selection easy and with less clicks on the mouse.just move the mouse over the image, look at the color and select the color you need.the data can be placed anywhere, I just placed it there since its connected to the tool.
This would be great to have on other tools, like the (Magical) Fill Bucket so we can select the color we want to fill with other color etc...or the Magic Wand selection tool to select the color with the RGB info we want.

I'm trying to show, using the eyedropper tool, the actual values of pixels in an 8-bit grayscale image (Mode command confirms that's what's there). In the Info panel, the eyedropper tool displays percentages for every type of color information (K, CMYK), while the "8-bit" field remains blank.

When I want to use the "Eyedrop" tool to pick up the RGB value of a colour, and zoom in to pick up an individual pixel, the pixels change in colour to go with the shades of the picture. Is there anyway to expand the range of the tool to a greater pixel range to get the basic idea of what the value of the colour is?

I'm attempting to tilt this image for use in a game im writing. I've been using Map Object and rotation (Y) but this then causes pixel color changes on the boundary with the background color. How would I tilt this picture without getting the problem?

I am trying to quantitate data on some black and white microscope pictures I took, but the images are too bright in parts and I need to darken them down.
Is there a way that I can use photoshop to darken certain pixel values within the photo?
I have tried adjusting the levels in the picture so that the greys are limited, and I have tried changing the greyscale, but to no avail.
I need to make it so that two images have the same pixel values so that they can be calculated evenly.

I'm editing an sRGB image. My custom proof condition is set to sRGB IEC, preserve numbers unchecked, intent PER or RC, BPC. Gamut warning is turned on.
I add some text and color it using the text color selector tool. I enable gamut warning in that and choose an out of gamut color such as #ff0000. I return to the image and the the text is *not* flagged as being out of gamut.
In fact *no* color flagged as OOG in the selector seems to be considered OOG once I return to the image with sRGB IEC selected, though they are when I select other devices to simulate.
Why the disparity between the image OOG warning and the selector tool? Is the tool using a different simulated device to that I've selected?

It blows my mind that somthing this simple isnt all that simple. I used the eyedropper tool to slect a color from another photo, then used the brush while fully magnified to change the color of each pixel.
It was coming out a weird greyish color, and I noticed that if I clicked more than once, it got darker, but so did the pixels directly around the one i was editing. So, i copied both pictures, loaded them into paint, and went to town.
It worked, but then when i copied it back into photoshop, it had a black background (there was no background in the original pictures) around the sprite I was editing. I tried to use the magic wand tool to get rid of it, but it took parts of the sprite with it, so...
Is there any way that I can edit the color of a single pixel (or hell, even a group of pixels if they share the same exact color would be nice...preferred, even) accurately? If not, what program could I use that would keep the transparent background?

I need to look at the pixel intensity of a gray scale image to write some code. I have used some trivial softwares like paintshop pro earlier where you can see the pixel intensity being displayed along with the co ordinates of the pixels as you slide your mouse pointer across. In Gimp 2.8 for windows, i can see the co ordinates but not the intensity. My image is a grayscale image.

--Toolbox: The 2 columns of Tools on the left side of the Editor screen.
--Foreground Color & Background Color: The color filled squares at the bottom of the Toolbox.
--Color dialogue box: This is the pop-up that is labeled at the top with "Color". It shows 48 different color squares (6 rows by 8 columns); they are labeled "Basic colors:". Right below the "Basic colors:" array is another 16 empty squares (2 rows by 8 columns) to be filled with colors to be defined. There is a "Define Custom Colors>>" button when clicked opens up a color picker with HSB RGB stacked below the color field screen. See this link to the Microsoft "Color Dialogue Box", [URL]
--Adobe Color Picker: The interactive dialogue box with the color field screen to the left and the HSB RGB numbers stacked on the right side.

The problem:In PSE 10, when using the Eyedropper Tool or clicking on the Foreground Color or the Background Color, the Microsoft Microsoft "Color Dialogue Box" pops up instead of the "Adobe Color Picker" dialogue box. This started about a month ago. I use Windows 7.
I want the "Adobe Color Picker" to pop up (like it used to) inside PSE 10.

if you look at the image attached the colours on the right are what the color picker is displaying and if I use that hex code thats the colour the web page displays, but if i fill in any element the colours circled on the left are shown in photoshop.
Why is the color picker window showing a different color to the whats displayed?

I'm assuming this problem I'm having stems from having color-calibrated monitors, but let me know if I'm wrong!
To preface, this is the setup I have:
Windows 73 monitors as follows, all have individual color profiles calibrated using the Spyder 3Cintiq 12WX Dell U2410Dell 2409WFPPhotoshop CS6 - Proofed with Monitor RGB, and tested with color-managed and non-color-managed documents . I usually do most of my work on the Cintiq 12WX, but pull the Photoshop window to my main monitor to do large previews and some corrections. I noticed that the color picker wouldn't pick colors consistently depending on the monitor the Photoshop window is on.
Here are some video examples:
This is how the color picker works on my Dell U2410:

This is how it works on my Cintiq 12WX:
[URL].........
Main Question
I know the Cintiq's video capture makes the picture look more saturated than the Dell's, but it actually looks fine physically, which is okay. But notice how the Cintiq's colour picker doesn't pick a matching colour. It was actually happening the opposite way for a while (Dell was off, Cintiq was fine), but it magically swapped while I was trying to figure out what was going on.
Semi-related Question regarding Color Management
Color management has always been the elephant-in-the-room for me when I first tried to calibrate my monitors with a Spyder colourimeter years ago. My monitors looked great, but Photoshop's colors became unpredictable and I decided to abandon the idea of calibrating my monitors for years until recently. I decided to give it another chance and follow some tutorials and articles in an attempt to keep my colors consistent across Photoshop and web browsers, at least. I've been proofing against monitor color and exporting for web without an attached profile to keep pictures looking good on web browsers. However, pictures exported as such will look horrible when uploaded to Facebook. Uploading pictures with an attached color profile makes it look good on Facebook. This has forced me to export 2 versions of a picture, one with an attached color profile and one without, each time I want to share it across different platform. Is there no way to fix this issue?
Pictures viewed in Windows Photo Viewer are also off-color, but I think that's because it's not color managed... but that's a lesser concern.

You know how when you're painting, you can hold ALT and it will pick a colour from the canvas? Well, for some reason, mine still picks up the colour but it sets it to the background colour instead of the foreground colour.
And when I actually select the colour picker tool, it will only select the background colour but when I hold Alt, it selects the foreground colour. Basically it's flipped where it's supposed to select.

When I have any kind of layer, and I want to change the foreign or background color (with the color picker) I just cant. When I click on the foreign or background color it automatically selects the eyedropper tool, and I don't want this to happen.

When I try to edit the color of a shape layer by opening the color dialogue box of the shape layer, the color that is picked up is a lighter color than the color I clicked on.
The eyedropper is set to point sample and all layers. This problem does not occur if I open the color dialogue box that is part of the toolbar.

Is there a way to choose colors outside of the Photoshop application using the Color Picker? Coming from Macromedia Fireworks, I have become accustomed to using the Color Picker tool within Fireworks, which enables you to pickup any color outside of the Fireworks application.
I have seen thrid party tools that let you choose colors from various programs, but they just give you the color scheme and you must type in these color values within Photoshop.

I am interested in setting up a plugin that is able to read the greyscale values of a defined number of pixels throughout an image, average them, and then generate shapes based on the value output.

I managed to remove the background, of an image,(A whit background) and put the image on top of a transparent layer. made a transparent image. When I place this image over a light color background, it looks fine, but when I place it over a dark color background, the edge of the image looks very rough and dirty, I think it's because some of the anti alias from the original image, how can I make it a clean image without going to delete pixel by pixel?

I am a new user to paint.net, because the tool I used for complex image manipulation does not run on the OS of my new machine. Although I could easily purchase the newest version, I needed work on some pictures now. Paint.net was easily available and does most of the thins I need at the moment. In addition, it is officially supported at my work place, so it's a good idea to learn how to use it.
Paint.net has some great features and a cute UI, but there are some issues I would like to see improved. The one at the top of my list is the font preview. I am doing some text on a number of pictures and want to check out some fonts. Unfortunately I can't change the sample text in the font list (at least I do not know how).
However, meanwhile I found a even better function (actually the way I would like to see it). When the font list is open, I can scroll through the list and the text will instantly updated. Cool.
Great thing would be to move the color picker out from the tool box into the color selection, so that it would be always available. Also it would be useful to not only pick one pixel sometimes but the average of a greater area.

Working in Illustrator CS5 on a Mac. When choosing a color in the palette, the preview showing up is different than what is in the palette. If I hit "OK" the actual color chosen is the one in the palette, not the preview window... Including some pics for reference. In my 10+ years of using Illustrator, i have never seen this.I am using a Dell monitor on a mac... not sure if that would make a difference.

what is still missing in smoke is having the color wheel while picking a color. The color wheel will enable us to pick any color straight from the wheel , it's much faster rather than trying to mix the desired color using RGB combination. it will be cool to see this feature in next release.

I have PS CS5 (version 12.0.4x32). The Color Picker HUD doesn't seem to work (shift-alt-right click). The Enable OpenGL Drawing box is greyed out and there's a note that PS "Standard" not supported. What's going on? Do I have aversion of PS that doesn't support the Color HUD? How do I find out if I have PS "Standard" .

I have been working with CS5 for a few years now and have never had any issues with anything but recently i updated my videocard driver and now the colors in my color picker have changed. They have become more "choppy" and it seems as though there is not, by far, as many color's to choose from. This screenshot explain.

I am seeing something very strange when I attempt to access the HUD color picker in PS CS6. The picker only displays when I have the PS Preferences box open. If I use the keyboard shortcut of 'control+option+cmd click' with only the image open minus the Preferences I get nothing.
I am using a MacPro with NVIDIA GeForce 320M.
