what the technique is called when you swap the values of two of the colors within a selection?
For example, let's say that we have a nice pinkish color for something... but you don't want pinkish. This would keep things looking relatively nice, simply by swapping all the red values with the blue values, giving you nice lavender-ish color instead. Or perhaps swapping blue with green values, giving you a more orange-y color.
Is there a way to select pixels in Photoshop based on given Lab values? I am using Select --> Color Range with a specified "fuzziness" threshold, but I'd rather make the selection based on specific Lab values instead of random pixels that I choose with my eye dropper. Is there a way to do this in Photoshop, or does anyone know of a plug-in that might do this?
View 6 Replies View RelatedI 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.
I have an image, and there's a part of it that's red that I want to turn into a different shade of red (or a different color altogether)--but I want the rest of the image to remain unchanged.
How do I do that? (This is seriously the first time I've ever used a graphic art computer program of any sort, so I am a complete square-one newb.)
It seems like such an insanely simple thing to do, yet I've searched and searched the internet, and it seems like all the tutorials I've found don't work or leave out some sort of important step that I don't get, and I just can't get it right. The best I've done so far is to convert *most* of the red stuff to a different color, all except the outer edges, making it look pixelated and gross.
I want to take a selection, see all the colors listed within my selected area, and be able to tweak each color to whatever other color I want. I hope that makes sense, if it doesn't say so and I'll see if I can come up with a different description.

I have a grayscale image (pencil sketch with pencil shading) of a glass object in a CorelDraw document. I'm tired of having to go to Photoshop Elements to edit images in CorelDraw docs, so I opened it in Corel PHOTO-PAINT X5 from within CorelDraw to edit. I want to change the image's 'white' (actually slightly gray) background to a color appearing in the CorelDraw document.
I tried using the Magic Wand to select all of the 'white' background, but the popup says the WAND only selects ADJACENT pixels! Isn't there a way to select ALL pixels of a given color like in Photoshop E. (conitguous/non-contiguous)? If there is a simple way (without the Wand) to change the background color of an image (not of a PP doc!!), I would nevertheless also like to know how to select non-contiguous pixels of a particular color with the wand. Also how to invert a selection. Also, how to select a color in CorelDraw to use as a fill color in PhotoPaint (both X5).
I notice with GIMP 2.8 that I can't type in numeric values if I want to scale/rotate/etc. a selection. I can use the mouse to manipulate my selection freely, but I'm pretty out of luck if I want an exact value (though I know that I can hold Ctrl for certain snapping, which is extremely useful).

I've tried a bunch of different things but I am still new to lisp.
As long as a cmm is set up it is not possible to me to measure the same color value on screen (with an external color picker) that I entered in Corel's color definitions. This only works, when I turn off any cmm in Draw.
Plus it is not possilbe to export a pdf in which I can measue the RGB values that I defined in Draw. The closest I get is without a cmm (see above) but I still get readings that are off by 1 in most cases (I don't figure why rounding issues should be acceptable here).
The only export that works for me is to export for "Office" .. only then all values are exactly how I had defined them.
I have a file from a client that has a table with the color values recorded as CMYK. (e.g. 50, 0, 10, 0)
I'd like to display the colors but I can only figure out how to do it if it's in the 256 color format. Is there a way for me to convert CMYK color values to a 256 color value. I realize the hues/colors won't be perfect, and I'll be happy with colors close to what the original data was using. Maybe there's a way to go from CMYK to RGB, and then to 246?
While I was messing with the HSV values in the pallette window I noticed that often some of the values would change from what I'd specified by increments of 1 or 2. I understand that this is a pretty small change but I still found it bothersome that something was keeping me from having complete control over what I wanted the color to be.
Is this intentional? Is this some overlooked bug? Is this common in other digital art programs? Some unavoidable result of whatever is used to calculate the color values? Something I'm missing here?
So I am measuring the 'red' 'green' and 'blue' values of a picture after I adjust the white balance with a grey card.. I notice that if I measure the colors from 'selected layer' they are different then if I select 'entire image' those are both different if i do not do any white balance adjustment..
Which is the correct measurement that I should record? I want the the white balance adjustment included.
I have a photo of an object on a black background, and during the editing process the cmyk values of the black background are c=75 m=68 y=67 k=90. As this image is to be placed on a business card, if it is possible to change the values to 100% K or 40% C 100 %.
View 3 Replies View RelatedAbout color lab color correction, in those days i'm watching a lot of tutorials about cause i'm trying to understand this new to me subject in a better way.
While neutralizing color, correcting a photo in Lab by Curvas adj Layer, the default eye dropper values are:
Black- 0, Gray- 128, White- 255 RGB (0-54-100 Lab)
To prevent the possibility of out of gamma some tutorials suggest to change the above mentioned default values:
Black from 0 to 26 RGB (0-6 Lab), White from 255 to 243 RGB (0-96 Lab)
What about the middle eye dropper Gray? A few tutorials mention to chage the gray value too from 128 to 133 RGB (54-56Lab) while the majority never mention gray value, they tell about black and white never mentioning the gray value; what is your experience about?
The above mentioned "out of gamma problem" is mainly related to output printing or to screen displaying too?
Generally speaking I would like to receive some comment by you gurus about this very subject, while working in Lab, what about your Curvas adj Layer eye dropper values, do you change them or you leave them as default?
If there is a way to make Outline Same as Fill - is there a way to Transfer color values from object to another?

Is there a way to select a portion of an image and display the average RGB or Lab values of that area? Right now I can only see the values of selected individual pixels. Instead of manually adding up these values to get the average value which is quite tedious, can someone help me to a better option?

View 9 Replies View RelatedI've been placing photoshop tiff files into Illustrator, and doing this seems to change the color values, when I sample them with the eyedropper tool. The images I made use a custom mix of CMYK rich black, with the K set to 100. In Illustrator, they appear to revert to the default 'Photoshop black", approx C75 M68 Y67 K90. This is not my intent of C70 M60 Y58 K100. The Illustrator document is CMYK mode, and I don't know why this is happening. The non-image items (vectors) in my illustrator file DO retain the color values I intended, however.
Is this some kind of setting I can change in Illustrator? Will this discrepancy show up when this file goes to print?
I have some c# code (though it could be any language) and I am trying to copy the colors used therein into an Illustrator design.
Here's the code:
private static readonly Dictionary<string, SolidColorBrush> _DefaultModeColours = new Dictionary<string, SolidColorBrush>
{
[Code]....
The colors are specified using hexadecimal numbers for the ARGB values.
In Illustrator I have the following color chooser:
I could fire up a calculator and convert each of the (nonobvious) hex values into decimal, but I imagine there is an easy way to change the Illustrator settings for the document to use hex values. Is there? If so where do I set it?
I'm working in Photoshop CS 5.5 on a Mac, and I want to apply a specific CMYK color to a selection in an image. I create the color with the values C=0, M=100, Y=100, K=10 and add it to my color swatches. Then I select the section of the image where I want to apply the new color and fill it with the paint bucket. The color fills the section just fine and life is good. But then when I roll over the section with the eyedropper to double-check the CMYK values in the Info window, it shows that they've inexplicably shifted to C=9, M=100, Y=100, K=1.
View 4 Replies View RelatedI'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?

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.

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.

View 3 Replies View RelatedSomehow I've turned off the color selection so that I don't have a color when I select a part of a drawing on a layer. The drawing area stays black whether I have selected it or not and I don't know how to turn back on the color.
how I can turn on the color again so that when I select a line it changes from black to red or magenta or whatever?
Was explaining to a friend about shades of color -- human eye has Red, Green and Blue sensitive cones and each can detect about 100 shades giving a combined total of about 1 million shades that we can normally distinguish, well within the 16 million shades that a jpeg can show (256 x 256 x 256) or the 64,000,000,000 shades (4096 x 4096 x 4096) that a TIF can show.
I used the eyedropper on a JPEG to show how the values went from 0 to 255 for each of Red Green and Blue, but when I went to a TIF expecting the RGB components to go from 0 to 4096 it showed 0 to 65535. To me this is an inaccuracy in the eyedropper tool at least for Tifs
I was trying to emphasize that while we may think that by having a greater range of shades available in the TIF we can produce richer images with more variety of images it all boils down to the lowest common denominator - that our eyes are not capable of determining a range of shades more than 1 million.
Try this test -- set your foreground color to RGB 128,128,128 grey and using the paintbrush tool draw a line. Then double click on the foreground box in the materials palette and change say the red value to 129 and draw another line overlapping the first one. Repeat increasing the red value and see when the difference in shading becomes obvious to your eyes. For me I had to go from 128 to 135 before I could recognize a difference so that is 7 values which look the same to me. So I cannot see even the 16 million colors of a lowly jpg let alone the small differences in a Tif.
Material takeoff: As paint and other related calculations
I’m wondering why no values where calculated for the field “Material: as paint”! As for the “area” and “volume” calculation, they sound to be false, for example, the area of plaster board should be 0.02*1.84 but not 0.32*1.84! What might be false there?
I've been having a hard time googling this question as it's hard to put in bite-size words. I'm looking for an easy way to take the alpha levels of each pixel on one layer, and then combine that with the color levels of each pixel on another layer. Let me give you an example. I want to take the alpha levels of image 1, replace the colors with the colors of image 2, and be left with image 3 (Only no background, because the alpha level should be zero!)

I achieved the effect you see in image 3 by using the "difference" blending, and then inverting the image. Problem is, I've still got the gradient as a background which doesn't really work because that icon needs to sit on anything.
