Photoshop :: Finding Average RGB Or Lab Color Values

Dec 22, 2008

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?

Photoshop :: Calculating Average Color Of Pixels

Sep 16, 2008

I need to analyze an image and read the value of each pixel, exclude the highest and lowest values (perhaps anything less than 10,10,10 and greater than 245,245,245) , then average the remaining. I may need to do this on each channel of RGB.

I can almost get a result blurring the sample and then using a large brush with the info tool, but is there any other method more direct and all inclusive?

Photoshop :: Measuring Color Values After Adjustments

Mar 21, 2013

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.

Photoshop :: Color Lab (Curvas Eye Dropper Values)

Jun 7, 2013

About 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?

Photoshop :: How Do I Apply RGB Values ToTweak Color

Oct 12, 2008

I have a selection or a layer of which I want to tweak the color. I use my color sampler to read the RGB values from my "source". How can I apply those values to my selection/layer ? If I use a color fill, I lose all detail in my original.

Photoshop :: Color Range Selection Using Lab Values

Aug 4, 2008

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?

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?

Photoshop :: Replace Color Output Variables Do Not Correspond To R / G / B Values

Nov 25, 2013

PS CS 5.5.I want to replace color with a particular R,G,B value, but PS insists on some sort of difference setting that is not standard.  Clicking  on Final Value in the Replace Color window and entering treal values there has no affect, or has some seemingly arbitrary effect.

AutoCAD Map 3D :: Color Values Cmyk To 256

Jun 19, 2013

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?
