Grayscale spectrual display?

Hi! How can I change color schema in a spectrual display to grayscale? I found article for 3.3 version, but not for CS5.5 ..

In Audition CS5.5, the colors for the spectral display are not editable.

In the Info panel, how do I display pixel values as values, not as percentages?

I'm trying to show, using the eye dropper 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 eye dropper tool displays percentages for every type of color information (K, CMYK), while the "8-bit" field remains blank.
I've looked at Properties and pretty much everything else that I can find with no luck.
Photoshop CS6, 64 bit, Win7-64
Thanks!

Noel,
Thanks for your reply. I thought this had been fixed by recreating the Preferences file, but this morning I was back to percentages. I did have different settings in the Info Panel from the ones in your very helpful picture, and after I changed mine to match yours I now see 0-255 values in the R, G, B settings when using the eyedropper on this grayscale image.
Instead of RGB Color for the First Color Readout I had "Actual Color". This by itself causes percentages to be displayed. All options for the Second Color Readout all seem to produce percentages.
"Actual Color" is what I normally use for the first readout. In the case of a Grayscale document, it will display a K (black) value. For a RGB image, it will display R,G and B values. And so on.
When 8-bit is chosen for the value format, we expect a value of 0..255 to be displayed. As you know, that works fine for the RGB readout, but a Grayscale readout displays a percentage instead.
So if you set one of the readouts to RGB and 8-bit, you can get 0..255 values to be displayed for your Grayscale document.
When the document is Grayscale, the RGB values are a conversion from the document colour space to the RGB working space as defined in Edit > Color Settings. To get the true values of the pixels, the Grayscale document profile and RGB working space must be complementary (for lack of a better word). That's why, in my first reply, I said to use the following combinations:
Doc with sGray profile and RGB working space of sRGB.
Doc with Gray Gamma 2.2 profile and RGB working space of Adobe RGB.

What monitor is the best for gauging what the printed document will look like?

I am working on a 300+ page book that contains a lot of photos that I have converted from color to grayscale in photoshop. I am using a laptop computer and I cannot judge the quality of the photos on this laptop monitor. What is the best monitor for gauging what the finished product will look like? It is a hardcover book that will be offset printed. I do not know if this particular printer uses computer-to-plate technology or if it is "old style." Thanks!

If you are talking about judging the tonality of the grayscale images there are 2 color profiles that affect the display of a grayscale image. The monitor's profile-- the profile that is created when the monitor is calibrated and describes your monitor's display. And the gray profile that is assigned to the image, if no gray profile is assigned Photoshop's working gray profile is used. By default it is 20% Dot Gain. The accuracy of your grayscale image display depends on how accurate your monitor profile is and the accuracy of the gray profile. You can choose the default 20% Dot Gain but it might not be the press profile.

Driver for Nvidia Geforce needed

Is it possible to get Solaris 7 working with a Nvidia Geforce 256 DDR chipset ? ( Creative Pro ) All I have at present is standard vga ! ! !
I only need to it to work in "open Windows " mode
Thanks

I am also looking for GeForce support under Solaris 8. XI Graphics
do not (yet) offer such a driver, and - judging from the discussions
in various newsgroups - I am not the only one who cannot get XFree running.
To get over the time until a working solution appears, a VESA driver
would be a nice thing to have, like in BeOS - it does not recognise my card either, but allows me to use a (admittedly slow) high-res desktop
with a decent color depth.
Is something like that available? The 640x480 in grayscale, plus display problems in CDE, are barely usable IMHO.

Display/save 8 bit grayscale image

I have a VI that is capturing an 8 bit grayscale image (1D array of 1500 pixels). It has a 10 byte header that I strip off and try to display it. The problem is that the displayed picture is interpeted as an RGB. Also, the saved image can be opened using a picture viewer but is not correct. It is missing the pixel data. How do I get this to display as an 8 bit grayscale image. I would also like to duplicate the 1 row of image data to about 50 rows so that it is easier to view. using a for loop and indexing the row only leaves the pxmao empty.
Solved!
Go to Solution.

Bjoles,
You are missing a colour table input to your flatten pixmap block. See the vi snippet I have attached. Also, I have found that building arrays from a for loop is a quick way of doing it, Labview seems to preallocate the memory correctly.

Screen Displaying in Grayscale

All of a sudden my screen has started displaying everything in grayscale. I did not change the setting and have double checked to see if it got changed but it hasn't. I'm not sure how to fix this. I downloaded ios8 last night so I'm also unsure if its related.I have an iphone 5

Two possible solutions that you might have already tried. Could you try toggling grey-scale on and off in the accessibility settings? And if that doesn't work then could you reset your iPhone by holding down the home button and the power button until the screen goes dark and comes back with the apple logo?

After install the trial version of LR 2.3, it only displays as grayscale.

I installed the trial version of Lightroom 2.3. When I open the program and import pictures, I can only see them as grayscale images. I feel stupid, but what am I doing wrong? How can I view them as the color images they are and edit them?
Thanks, Phillip

I still can not figure this out.
Windows XP SP3
Lightroom will apply the filters and if you save or export the "change" photo, you can see the result.
However, the entire workspace is desaturated with no color except for the color flags. They actually display in color. (see attached jpg).
It would be nice to see this program work as I am interested in purchasing it.
I deleted all catalogues, uninstalled, cleaned out all I could from through regedit, reinstalled, didn't change a thing.
Any other ideas would be helpful.
Thanks.

Reader displays only black-and-white (grayscale)

A customer of ours is telling me that my Illustrator-CS2-created PDF's appear to her in grayscale-only. Those same PDF's show their proper colors just dandy on everybody else's computer I've tried, so obviously it's something on her end.
Sorry, but I don't know what version of Reader she's using, and it will be useless attempting to ask her.
I can't find any setting in Preferences in my copy of Reader 9 to "view as grayscale". What could be the problem?

I think I see what you are saying now:
You have the tv connected to a tv by the yellow lead of a composite connection set. You have it working in B&W. You did get colour for a short time, but now it's gone back to B&W. You want the colour back.
If this is correct it's not going to work, you may get B&W if you connect it to the right component port, you may even get flashes of colour (which you seem to have done), but this isn't an indication that it will work, it's not going to get any better than that.

Using Export for Kindle, how can I get black body text to display inverse (white on black) on Kindle

I'm using ID 5.5 on a Vista system.
I've created a book file with some colored fonts and anchored gif images. Basic paragraph (body text) is black. The "Export to Kindle" mobi file displays fine on Kindle for PC and Kindle Previewer.
Kindle PC alows viewing on white, sepia or black background. Works fine on white and sepia, but when the black color mode is selected (night viewing option) the black text does not display as white text. What can I do to have the black text automatically change to white?
While trying to find a solution, I created an epub file of the book and, using Calibre, converted it to mobi. When this mobi file is loaded into Kindle PC, the black text does automatically change to white when viewed on the black screen. I would use this method of creating the mobi, but there are several other issues that make this process unsatisfactory (other text colors don't work well, image transparency losses, etc).
So, how can I get the black to white text thing using only Export to Kindle?
Jim

Grayscale is probably the best (Settings>General>Accessibility>Grayscale)

EDIT: If you would like a black color scheme, use the suggestion in the reply above.

W540 - Sound and Display in Linux

Hey dear supporter/user/reader!
After calming down due to the vast loss in quality of the new Lenovo ThinkPads (2.2k€ for such a plastic toy - rly?) I started installing a Debian sid with XFCE d/e. There were a couple of problems to solve, especially this rattly one-click-fits-all clickpad needed a lot of caring and compiling. And not to forget the first two days of my odyssey trying to boot up the machine with my OCZ Vertex 2 SSD installed with any format, partition table protocol or whatever firmware loaded - which was a sobering and vain experience. I ended up taking another SSD from my studio desktop which isn't only half the size but slower, too. 2.2k€ for a machine unable to boot a regular SSD - rly? Whatever, posting my whole snaggling-list would go far beyond the scope of this thread and we all know how capitalism and "consulting" works - so let's look forward.
There are lots of problems left but some of the major ones are:
Bad sound in Linux
Bad color reproduction from the 3k display in Linux
Sound:
In Windows the sound is quite nice. I know that it's a problem of alsa/pulseaudio drivers and that the community has to create appropriate drivers first. But there's no information around by now about the capabilities of the installed sound chip to create some usable workarounds:
Is there a subwoofer built in?
Or other channels/speakers I can route some signals to?
How is this full, brilliant and wide sound achieved in Windows?
Because just using the stereo speakers at the front edge of the notebook sounds really crappy. Routing the signal through an equalizer gets back some of the highs and the "bass" and eliminates some of the bugging mids around 1.5k but it is still far from the sound experience in Windows. And it brings in some problems because I have to setup a dirty workaround via DBus to select different presets in the e/q depending on the selected output device (speakers or headphone jack) which introduces more and more problems with muted channels after plugging a headphone aso.
Display:
The colors look quite okay in Windows, in Linux it's a yellowish-green mess. Since I read about the pretty poor quality of the built-in colorimeter before I ordered this device I didn't buy it in anticipation of the tutorials about using the Windows color profiles in Linux. Unfortunatley copying the profiles from the Windows HDD (C:\WINDOWS\System32\spool\drivers\color) and loading any of them via xicc, xcalib or any other tool handling color profiles does nothing to the color reproduction of the display. I found a profile made by a helpful person somewhere on the internet (notebookcheck? Unfortunately I don't remember) which makes this display kind of usable but it's far from being correct since it introduces a greenish inking at the lower end and a rose red one in the middle of the spectrum. Additionally the overall gamma curve doesn't fit that well. But at least it draws white as white and eliminates the overall lime style of the device.
Résumé:
Maybe I'm just an idiot, too dumb to correctly copy and apply color profiles or to use alsa/pulseaudio the correct way. If so I would be very happy about anyone who would lead me in the right direction. Perhaps someone stumbled over the same problems and has some fixes or at least ideas where to look at. Perhaps someone calibrated his 3k display with a professional colorimeter and is willing to share the results.
If someone is interested in e.g. my Xorg config, the amd64 DEB package for getting a usable clickpad, the slightly working color profile or other informations I'm able to share, please let me know.
Disclaimer:
I can understand if anyone is deterred by this rant in a way that she or he avoids to talk to such a poor goof, but perhaps someone understands my vast disappointment after spending a huge amount of money and a lot of time for a brand which is (was?) well known under (Linux-) enthusiasts for the outstanding build quality, the overwhelming compatibility and the ubergood hardware which was built into ThinkPad machines in the past. I owned, sold, recommended and installed lots of these notebooks before, my own last two machines were two t61p which I would call the peak in quality of this brand. But those times definetly seem to be over.
Thankful for every hint to make this thing more usable, best, Markus.
Your ads here!

Here's another profile I stumbled upon. It was made for the T540p shipped with the same display. It is a little more even, so less different colours in the overall grayscale and it has a better gamma curve. But it has an overall greenish touch just like the display without any profile but considerably less.
http://mein-neues-blog.de/files/t540p.icm
And to prevent users from searching I upped the profile from my last post to my blog, too:
http://mein-neues-blog.de/files/LEN40B5.icm
BTW I'm actually hacking a GTK application for manipulating the ramps of a LUT profile in realtime since those profiles are not that bad but need a little tweaking to fit my own display.

How to create Image from 8-bit grayscal pixel matrix

Hi,
I am trying to display image from fingerprintscanner.
To communicate with the scanner I use JNI
I've wrote java code which get the image from C++ as a byte[].
To display image I use as sample code from forum tring to display the image.
http://forum.java.sun.com/thread.jspa?forumID=20&threadID=628129
import java.awt.*;
import java.awt.color.*;
import java.awt.image.*;
import java.io.*;
import java.util.*;
import javax.imageio.*;
import javax.swing.*;
public class Example {
public static void main(String[] args) throws IOException {
final int H = 400;
final int W = 600;
byte[] pixels = createPixels(W*H);
BufferedImage image = toImage(pixels, W, H);
display(image);
ImageIO.write(image, "jpeg", new File("static.jpeg"));
public static void _main(String[] args) throws IOException {
BufferedImage m = new BufferedImage(1, 1, BufferedImage.TYPE_BYTE_GRAY);
WritableRaster r = m.getRaster();
System.out.println(r.getClass());
static byte[] createPixels(int size){
byte[] pixels = new byte[size];
Random r = new Random();
r.nextBytes(pixels);
return pixels;
static BufferedImage toImage(byte[] pixels, int w, int h) {
DataBuffer db = new DataBufferByte(pixels, w*h);
WritableRaster raster = Raster.createInterleavedRaster(db,
w, h, w, 1, new int[]{0}, null);
ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
ColorModel cm = new ComponentColorModel(cs, false, false,
Transparency.OPAQUE, DataBuffer.TYPE_BYTE);
return new BufferedImage(cm, raster, false, null);
static void display(BufferedImage image) {
final JFrame f = new JFrame("");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().add(new JLabel(new ImageIcon(image)));
f.pack();
SwingUtilities.invokeLater(new Runnable(){
public void run() {
f.setLocationRelativeTo(null);
f.setVisible(true);
And I see only white pixels on black background.
Here is description of C++ method:
GetImage
Syntax: unsigned char* GetImage(int handle)
Description: This function grabs the image of a fingerprint from the UFIS scanner.
Parameters: Handle of the scanner
Return values: Pointer to 1D-array, which contains the 8-bit grayscale pixel matrix line by line.
here is sample C++ code which works fine to show image in C++
void Show(unsigned char * bitmap, int W, int H, CClientDC & ClientDC)
int i, j;
short color;
for(i = 0; i < H; i++) {
     for(j = 0; j < W; j++) {
     color = (unsigned char)bitmap[j+i*W];
     ClientDC.SetPixel(j,i,RGB(color,color,color));
Will appreciate your help .

Save for Web... and grayscale images

I noticed a strange behavior when I use "Save for Web and Devices" on scanned BW negatives...
I import the negatives via the scanner's twain driver in Photoshop as 16bit grayscale images. My grayscale working space is normally set to the default DotGain 20% profile. When I want to show these images on the web, I use "Save for Web and Devices..." and I have selected the convert to sRGB option. For some reason, the "embed color profile" option is disabled (grayed out) when the document is in grayscale mode.
When I view the the exported image (in a color managed application or browser) it looks too dark and shadow detail is lost. Examining the file info shows that the JPG file is in RGB color space and has the sRGB profile assigned.
When I convert the image to RGB mode before I do save for web... the exported image will look exactly like it looked in Photoshop. Also, the mode change doesn't cause a change in appearance. Also, after changing to RGB, the "embed color profile" option in save for web... becomes enabled.
I experimented with other working color spaces and noticed that an image exported from a grayscale image in "GrayGamma 2.2" working color space will display almost like an image that was exported from a grayscale image converted to RGB.
I would like to understand this behavior and whether it is correct. My assumption would be that a conversion to sRGB during the export should yield the same result like a manual conversion of the image in photoshop but for some reason the results are quite different.
How can I export my grayscale images to sRGB JPG without having to convert to RGB manually while preserving the tonality from the original image?
I have attached an image which I hope might illustrate the effect I'm describing. The crop on left hand side looks as expected and is the result of exporting from an image that was converted from grayscale to RGB mode (sRGB working space) before using save for web...
The image in the middle is the result from converting to GrayGamma 2.2 color space but leaving the image in grayscale mode before saving for web and devices. It is almost identical to the crop on the left. The crop on the right hand side is the result of using save for web and devices from the original image in grayscale mode with the default DotGain 20% profile.
Thanks

These are my settings. Are they the same in your SFW dialog?

Using PhotoShop CS2: should i adjust my display colours?

I've never had to consider this before, but seeing my images on a pc made me wonder:
I have a lot of slides that I used to teach a course in photography, about 15 years ago. They are photos of images in books, mostly taken on tungsten slide film because of the lighting I used. The colour of the slides themselves is still very good.
I scanned the slides with my Epson (Perfection 3490 photo scanner). The scans of slides of black and white images are fine (probably because I set the scanner to grayscale), but most of the colour images have a reddish cast to them.
I opened them in PS CS2 and did some colour correction (levels, curves, replace colour, whatever worked)... did some at home on my iMac, and others at school on the pc (don't know what kind, but a flat screen monitor). I noticed that some of the ones i had opened at home, but hadn't corrected, looked much better on the pc, and didn't need as much correction as I thought.
Then tonight, i opened up (on the iMac) the ones i corrected at school and they look washed out and wimpy. Yet, the contact sheet that i printed (Epson stylus colour 880, on glossy paper) shows almost the correct colour, but not at all like the wimpy image on screen.
Should I be making some changes in my display, in System Preferences? I have it at the imac default, with 1.8 gamma and D65. Or should I make some changes to PS's colour settings?
(FYI, when i upload pictures off my camera, what i see on screen is pretty much what i get on the paper, but I don't print very often)
(and: when i open these scanned images I get the 'no colour profile ' message and i tell the app not to colour manage)
More FYI: i need these images for a new photo course I'm teaching, adding them to powerpoint instead of projecting slides, and would really like the images I show to be the correct colour, but if what I see at home isn't what i show at the school, I'll have problems. (The school i'm presenting this at is not the one I'm teaching at currently so I can't check it out ahead of time)
Any help would be appreciated.
Thank you

I have it at the imac default, with 1.8 gamma and D65.
That's the main issue with the images looking washed out on the Mac. In Windows, the default gamma is a much darker 2.2. Change your Mac's display profile to match that gamma setting and the images should look much closer to how you see them in Windows.
The scans of slides of black and white images are fine (probably because I set the scanner to grayscale), but most of the colour images have a reddish cast to them.
Your scanner needs to be profiled to get the correct color for items you scan. Check to see if your scanner came with any. Although I don't know if the Epson software supports ColorSync. If it does, using the correct input scanner profile will give you much better color. Assuming you have accurate profiles.
when i open these scanned images I get the 'no colour profile ' message and i tell the app not to colour manage)
That's an issue. Profiles are very important in RGB. They let color management software (Kodak in Windows, ColorSync in the Mac OS) know what to do with the image when you open it. That is, when the source and destination profiles don't match (both the monitor and image profiles), the software knows how to alter the image values so the picture looks close to the same on one computer as another. With no profiles embedded, ColorSync can't determine the original color spaces used when you created them in Windows.
If you can, you could set up an action in Photoshop on the Windows side to open each file and save them with an embedded profile. Which would be whatever your current working color space in Photoshop is. When you then open them on the Mac, Photoshop will know what to do with them to make the color appear the same. A second benefit is that some (not all) web browsers are aware of profiles. Safari is one. So even if your files have a gamma of 2.2, and a person visiting your web site has their monitor set to a 1.8 gamma, Safari can adjust the color of the images on the fly to have them view correctly by knowing the difference between the embedded image profiles and the user's monitor settings. It's not perfect, but works pretty well.

20" iMac Intel Core 2 Duo Display problems.

It was hard trying to sum up my problem for the thread title... so let me try and describe what I am experiencing a bit more clearly.
I have recently acquired a 20" iMac Intel Core 2 Duo,2 GHz(aluminum body black plastic back)-with display issues...
The problem is basically that there appears to be no happy middle ground in regards to contrast- it is either WAY too white or WAY too black... I would have to say it is more of an issue with CONTRAST than brightness, it appears that nothing I can do in calibrating the screen really matters.
I have calibrated displays before and never had this sort of issue. It is pretty bad (for example): a royal blue appears as black or gray mac highlight color choice appears as black.... white and medium grays appear indistinguishable.
all this in addition to the fact that there appears to be a gradient to the screen when you display a solid color neutral back ground, not too mention that it is VERY hard to look at this screen for very long and for what I do( 3D model making and texture creation) the display is pretty useless.
I have read about similar issues with this model's screen at other sites, but most of the threads ended without being resolved and were more than a year old.
This machine belonged to my in-laws and according to them, it always looked this way and when they took to back to the Apple store few weeks after purchasing it( brand new), they were told there was "nothing wrong with the display, it's supposed to look that way"... the machine was hardly used(just for iChating with our infant daughters), so I don't really think it is an issue with age or anything.
Now here is the really weird part:
I just upgraded the OS from 10.4 to 10.5 and when the machine first displayed the default 10.5 background(the Nebula one... blueish-pink with stars)... as it was going though the start up IT LOOKED RIGHT.
Once everything was done and all my icons appeared- Boom! Back to ugly.
I have noticed the same thing occur if I shut down the machine.
Startup screen, the default (nebula)background(my choice of background) comes up... it looks fine, the icons start to show up... everything still looks good and then when everything is done... BAM! UGLY!
I'm not sure what to make of this... any suggestions
One last thing- I am VERY familiar with the default background for OS 10.5, I have used it on my iMac G5 for over 2 years. When I say the displayed "looked right" I mean, it looked like what I was used to and how it appears on other machines.
Thank you in advance for any help or suggestions.

mcgyver,
If start up and shut down look correct then something is set or corrupt in the user options. To test this, add a new user and signon as them.
Regards
Edit: I don't use 10.5.8 anymore so the following suggestions are for 10.6.5.
The things that may affect your display are:
System Preferences > Universal Access > Seeing Tab. Display: Make sure Enhance contrast slider is set to normal. Use grayscale is unchecked.
System Preferences > Displays > Color tab > Display profile set to display or iMac. Whatever the default is on your system.
