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 am trying to to use Colour to Alpha by picking a specific colour from an image. But I can't get the colour picker to work.
The image has an alpha channel.
I choose Colour to Alpha, then click on the From swatch. The Colour to Alpha Colour Picker window appears. I click on the eyedropper. But when I move the eyedropper over the image, the cursor changes to the previous tool that was used. For example, if I used the zoom tool, the eyedropper changes to zoom as the cursor leaves the Colour to Alpha Colour Picker window, and zoom becomes active.
How do I pick a colour from the image?
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?
I am using PhotoShop CS5 and can’t select colours using the colour picker on different layers.This used to work but now I can only select the colours from the same layer?

View 9 Replies View RelatedI have 2 Macs with Photoshop and one of them has the colour picker set to a "different" look. The colour field and colour sliders on my main 'puter are "normal" having a full spectrum of colour. But the other one shows only a narrow range of colour. Well, there is the whole gamut of colour but it is shown in a weird way. I've been through the preferences and nothing addresses this issue. The attached jpg has the weird picker on the left.
View 2 Replies View RelatedI use the alt button when using the brush in photoshop to quickly switch between the brush and colour picker, and it usually switches the colour i have chosen to the foreground colour so I can use the colour I picked with the brush.
but I think I pressed something or I'm not sure and it stopped doing that and I've restarted my computer and photoshop numerous times and it won't change.
what happens now is when I use the alt while using the brush the colour picker selects the colour but selects the colour for the background colour and leaves the foreground colour unchanged. =(
today I found if I click on the colour picker icon and click on a colour it'll select that colour for the background colour, but if I have the colour picker as my selcted tool and press alt and click it will set it as my foreground colour.
If I have elements on separate levels and I use the colour range option to select the area, it works on all the levels, not just the level I have selected. That's not what I want! I only want it to select the colour range on that one level. The work around is to manually turn off other levels, but on a file with lots of levels, that can be tedious. Can this be avoided? Incidentally, magic wand works only on the selected level, but not colour range (or color range, if you are American).

I can't even minimize or quit the program!I’ve restarted photoshop several times, restarted my computer and this still happens every time I click on the colour swatch to bring up the picker.

View 2 Replies View RelatedFeature 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.

View 2 Replies View RelatedRecently, I started using Adobe Illustrator and watched many tutorials for the basics of it (coming from Photoshop) but one thing that I'm not too comfortable with is the gradient tool in Illustrator compared to the one in Photoshop.
I keep reading that the only way to adjust the colours is to either use the colours in the swatches or the mini colour slider but is there a way to choose the colours like you can in Photoshop?
I have recently upgarded from the 2.6 version to the 2.8, and I have serious issues with the colour picker. Every time I use the dropper to select the colour I want to use from a picture, it ALWAYS comes out as black, never as the colour I want to use (for touching up, etc).

View 4 Replies View RelatedI have two art objects on two layers. I want to match to the pixel the two objects that otherwise could be exactly the same but one layered object was imported slightly smaller.
The scale tool has good scale handling, I just want to measure the tool spots to the pixel to gain an exact scale size factor and match sizes.
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?

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?
View 2 Replies View Related We are developing an application using functionality of Gimp´s channel mixer with java.
Our problem is that we don’t Know how channel mix works exactly for transforming pixel by pixel in Java.
For example,
We have an image an do on it the next mix:
Output Channel = Red
Red=200.0
Green=0.0
Blue=0.0
For simulate that, we transform all pixels with Red Component *2 and 255 (maximum) if is greater.
Our problem is:
Output Channel = Red
Red=200.0
Green=60.0
Blue=0.0
How can I simulate that?
I'm using Photoshop CS5 and as you can see on the picture below, when I set my grid line to every 1 px, grid doesn't match canvas pixel size.

Whenever I create a new colour in the colour swatches it only stays there for a couple of actions while working on a project. I understand from others that once they create a colour it stays there. Why can't I get that to happen?
View 1 Replies View RelatedI am using CS6 and the Replace Colour Tool no longer allows me to replace multiple colours when I select the + . So when I have the panel open and I highlight the +, I used to then be able to click on several spots in my image and all of the colours that are in those spots are added to the selected colours that will be changed by using the sliders.
But now, when I use the + it has exactly the same effect as not using it - I can only choose one colour or an other, I can't add.....I want to reset this to the original way that this works.
Currently I have to open the panel, change one variation of a colour, save it, then re-open the panel and do it again (and again and again) until all the colour variations I am trying to remove are are changed. I know I also have the 'fuzziness' slider, but it does not give enough control.
I am designing a T Shirt for my ski club.I have taken an image from a banner (made in illustrator, full colour image attached) and I want to devide into a 3 colour image for the t shirt (I am only allowed 3 colours for printing).The colours I want to use are black, white and purple. The colour of the t shirt is a light blue.I want to then put the purple logo on top of the white and black too.So I'm after a black and white grunge background with a punchy purple logo on the top.All of this should be on a tranparent or, for design purposes, light bue (same as T Shirt colour) background.
how to split a full colour image into using only 3 (4 including transparent/light blue background) exact colours.
If I were going to black and white I might convert to grey scale and then paint areas to fully white or fully black using an overlay brush I don't think this works for me for more than just black and white though.
I have attached two of my attempts where I used the colour range selection and level adjustments. Niether was really successful though (one does not use the right colours or number of colours but looks quite cool).
I will like to find out the colour code for the background colour on a particular web address. Unfortunately I am new here so not allowed to post links so will say this as creatively as possible. the address is theregentlagos (with the usual prefix beginning with w and suffix beginning with c for all websites). I am referring to the colour where the menu items like logo, home, brands etc are on.

It seems the object only changes colour when I release the slider. But I want to see it dynamically change, so I can find the colour that works best without "hit or miss" - "trial and error" behaviour.
Yes... I'm aware some of you spend hours in colour programs creating a palette to work with. Good for you.
I'm just wanting to do it LIVE. Dynamically. In 2013. In Illustrator.
