Photoshop :: Colorizing Grayscale Image
Nov 11, 2006
I have a creative director who loves to bring grayscale tiffs into quark xpress, set the color of the tiff to one color and then select the image background "box" and set it to another color.
The result is visually ok, but it all has to be recreated in photoshop to print well. I have been using photoshop for years, and a duotone is not the answer, at least with the curves i have played around with.
What is the best way to recreate this effect in photoshop?

I have a grayscale image that I want to apply color to. I know how to do that by just colorizing it, but instead, I want to apply a color for the whole document. I know how to do this if I want it to be, say, blue (where black is 100 percent of my blue and 50% gray is 50% of my blue, etc.). But, what if I want a unique gradient across the image (where 100% is blue, 50% is 50% red, 10% is yellow, etc.)? How would I do that?

I happened to download a rather dark black and white entry into Photoshop and noticed it was several shades lighter in Photoshop than in my browser. It loaded in Photoshop in Grayscale mode. So I tried this:
1. Open Photoshop.
2. Set the background colour to 53 Red, 53 Green, 53 Blue.
3. Select File - New, set the Width to 800 pixels; the Height to 600 pixels; leave Resolution at 72; set Color Mode to Grayscale - 8 bit; set Background Contents to Background Color; and click OK.
4. Save as a jpeg (maximum quality).
5. Open the jpeg in your browser.
When I do this the browser image (I tried both IE and Firefox) is a shade or two darker than the Photoshop image. I used the Colorzilla extension in Firefox to measure the actual color displayed and it comes out at 37 Red, 37 Green, 37 Blue.

Lately I have been experiencing this weird problem. Every time I try to convert my image to grayscale mode, instead of just being black and white the image turns purple. Is there anyway to fix this problem? ....

I will submit the Black and white ad created in Photoshop to the magazine. The requiment is that for grayscale images, the shadow density should be no darker than 90% and highlights should be no lighter than 3%. I don't know how to check the percentage on the document I made. I checked HELP in Photoshop and website. But I couldn't really get answer from them. I have little knowledge of printing. Please give me advice or helpful website.

I have an image that is in grayscale and I need a table that displays each pixels grayscale value. Is there a way to save the image in some tabular format or can I convert it any other way in photoshop?

I flatten an Image, All the colors change to grayscale. Like if you look at the color chart, you see all the normal colors, but if you try to use a color it just comes out different shades of gray. Its horrible, and it happens everytime.

I use Photoshop LE 5.0, which has many of the BIG Photoshop features.
If I take a web page screenshot and turn it into greyscale and print that,
I still get some colors coming thru on the printout, even though it looks b/w on the screen.
Is this a common problem? Photoshop or Printer or Windows?

The image is basically a grayscale height map created from Digital Elevation Models, and exported out of another program as a 16bit tiff. I know photoshop can handle the idea of a 16bit image, but no matter what I do, these come out black. i've tried dumping it out as signed, unsigned, stretched, etc. I can't mess with things like contrast or brightness globally cause that will alter the values which have to stay the same.Basically it needs to open in photoshop cs5 as what it is and save off the same way.
I don't have any other way to do what I need to do to it other than photoshop, so if there is a way to make this work, and no, converting it to 8bit is not an option.

Why are the image thumbnails in the channels pallet not showing up as grayscale images? They used to, and for some reason or another aren't any more for me. Instead, they are showing up red, green, and blue for each respective channel. I'm on Mac, using CS6.

The starting point:
I have a JPG image of a battlefield wherein the height contours in feet are marked as faint lines (like a closed contour line for 390 feet, another for 420 feet, etc etc.)
The desired final product in Photoshop:
A grayscale RAW document that shows the height variations in gray tones.
Low lying troughs need to be darker and higher elevations need to be lighter.
See picture below for example:
I am ignoring the roads and other features in the battlefield.
All I am interested is the technique of converting the height contours into a smoothly varying grayscale image.
I am a complete Neanderthal when it comes to Photoshop. I do have a copy of Adobe Photoshop CS3 on my PC.
I have been toying around with the package on and off. But nothing useful has come out yet.
Now to my specific questions
*How do I bring in the height contours into Photoshop? I have tried the magnetic lasso tool and able to trace a height contour with good fidelity.
I am kind of stuck at this point. Do I save the selection to a new layer? Do I thus create one layer for each of the height contours?
Say one layer for the all the 390 feet contours, another layer for the 420 feet contours, one more for the 360 feet contours etc etc?
*Assume that I have somehow brought in all the height contours successfully into a new Photoshop document.
How do I create a gradient effect between the contours?
The lowest height in the map is 300 feet and the highest areas are at 480 feet.
Thus the area enclosed by the 300 feet contour lines needs to be darkest (pitch black) and the area enclosed by the 480 feet contour lines needs to be lightest (pure white).
The areas in between need to go progressively from dark to light shade.
How do I achieve this?
*Assume that I have created now a PSD document that has these smoothly varying grayscales. How do I convert this to a RAW image?

I have an old b/w photo that I want to colorize with a sepia tone, and I know how to do that. BUT i want to give the surrounding text the same colour value, and I cannot find the value of the color that I give the photo - it is not shown anywhere. My PS is from CS3.

way to colorize or replace black with a specific color without losing shades and highlights?
Say for example I would like to change a black car into a different color.
To replace a color, I'm aware that I can:
1) Use the HUE/SATURATION dialog box
2) Use the "Color" layer mode
3) Use Replace Color
4) Etc.
But I cant seem to figure out how to replace black.
I read somewhere that Black is not color but a tone. And that i need a color to replace a color.

how to use the match color tool to automatically convert one grayscale image into multiple output images based on a collection of color swatches? Or a better process to achieve this automated?
I have all the swatches in psd files in one directory. I can do them one-by-one but I was wondering if there was a way to automate this process and have it spit out and save the different images automatically based on the saved swatch colors.

I downloaded an image of the internet to edit [URL]......
Because I want to edit the base and put clothes on it and such. I opened the image in gimp and added the lines for the clothes on multiple layers. I went in to color it and the color showed up grey, any color i used turned out to be grey. Then I looked up at where they put the name of the image and it says: (greyscale, 6 layers) I assume that why i cant color it. is their any way to change this so i can add and edit color?

eliminate the fragments from a grayscale image. I used a JPG. You never get just black and white because of the edge transition. So, the image was made bitmap transparent, and contone recolored light and dark to red. You don't get edge blending this way. Xara alphe channel traces to black, therefore the image needs to be something other than black. I made a bitmap copy/alpha for tracing. You need a copy othewise the trace image would be gray scale. Xara seeems to take what is in memory. I think you can see the alpha channel traces black. Xara appears to trace from the bottom up, and the bottom of the image will trace to the background object.

I need to transform a selection of ranges of grayscale image in colors. For example: using GSM of a gray scale image as a parameter I want to recode pixels from 0 to 20 in red, 21 to 40 in orange, 41 to 60 in yellow and so forth... until pixel valued 256 in GSM.

i'm using gimp 2.6.11 on a windows 7 enterprise machine. I made some brushes in rbg mode and saved as gbr, and also converted some ps brushes by exporting an abr as a png in rbg mode then saving as gbr. my goal is to get a gbr brush that i can change the color to the foreground color. I tried changing the mode from rgb to greyscale but when i try to re-save as gbr i get an error message that brushes can only be saved in greyscale or rgba (!).
i've tried saving the gbr as a png, changing the mode to greyscale and then saving as gbr but i get the same error message.
Any good skin texture brushes for gimp that can be used with foreground color? It's for a digital portrait of a male so I need an orangepeel texture and some other skin textures that aren't too airbrushed.

I'm new to GIMP. I've used Adobe Photoshop for years an years and no longer have access to the license. So I've been giving GIMP a test drive for a little while. I'm confused as to why when I apply a filter to my image or layer it changes the color to B/W or grayscale? I'm sure this is a relatively easy fix, but most filters I'm using don't have many options and I can't seem to apply the filter "as is". It always changes my whole graphic to grayscale. See "Before & After" attachments.

I've had gimp for quite awhile now and ive never come across this problem before. im trying to use the layer mask with greyscale and inverted image just as i always have. but when i go to edit my color i get grey! ive always been able to change colors this way! i know that the mode is set to rgb. im on the correct layer. ive closed it. ive restarted my laptop.
If i click on the transparency part i get a big blob of color as i should. but on the mask it does what its supposed to but in shades of grey. i dont understand whats wrong! it always worked perfectly. . .
newest Gimp
windows 7
Only thing that i have changed is i have a new tablet but i still have the problem without the tablet

I've been trying to hatch a complex image with a single pattern, but with different stroke weights.
Here I added an image of a simple greyscale image with below the hatching that I'm trying to make. In short: I want to use only 45 deg. hatches in this direction. However, based on the grey value, I'd like the hatches to have different weights.
However, since this image is quite simple, only four different weights were needed. However, I'd like to know if there is an easy way to do this for complex images. For this image I just used pattern fills with different stroke weights, but I'd like a smoother and easier solution, preferably one where it would be possible to have many different weights without having to split up the image in thirty different parts and making thirty different pattern fills.
I'm not sure if this is possible, but I might be overlooking something. If it would be possible with a plugin, I'd like to know too. Even if there might be a workaround via Photoshop, and the end-result would not be a perfect vector, It'd be fine.

I have an image that has elements pasted in from PNG files, and those elements have some shades of green. I want printed output in gray scale only, so I did Image -> Mode->Grayscale. The image on screen went gray as I wanted. When I print it, however, I get an image in which *some* of the colored parts still are colored!

Is there any way I can directly make a grayscale image into an alpha transparency channel?
I mean, NOT involving selection? Because selection by color to layer mask,is really difficult what I need to do the selection threshold.
Why is it easy to turn an alpha channel into a grayscale image but not the reverse?

How do I quickly separate an image's channels into grayscale layers? I'll need to do this frequently, so is there an automated way? If there isn't, can it be done with python scripting? Would it take me a long time to learn how to write such a script assuming I know a bit of Python (as used in Blender), but haven't done any scripting with GIMP?
