Mini + TV = grayscale image?

I connected my mini with the Apple DVI - S video adaptor to an S video-Scart cable to my TV (PAL- europe)
I can only get a gray scale image (no color)
Sound is OK.
Is this a known problem, what is the solution?
Thanks!

You may also be interested in this thread. Suggestion from the thread is to use an S-Video to S-Video cable instead of S-Video to Scart.

  • Applying an adjustment layer / or adjustment TO a layer in a grayscale image is NOT happening!

    I'm a long time user of Photoshop, but must admit to being stumped here. I have a very high resolution scanned image from a B&W antique engraving, and I'm trying to "open up" some of the lines to bring out the details in the engraved image while keeping the image as close to the "line art" B&W of the original as possible.
    I have the image now "cleaned up," having taken out the yellow color casts, etc., and have a grayscale 8-Bit image in the Photoshop file.
    I've discovered that I can use an adjustment TO the layer itself, or an adjustment layer on the layer in the grayscale image to take away some of the density and "open up" the line art a little, so it has better details by effectively "choking" the dark lines back to make them less thick and dense.
    Here's the thing, though: 
    When I tried making the adjustments via image > adjustments > levels DIRECTLY ON the layer (instead of using and adjustment layer to achieve this), every time I hit the OK button to accept the adjustments I've made that way, the dialog box closes and the layer seems to revert to looking just the same as it did BEFORE I opened the dialog box to adjust the layer!
    When I try making the adjustments by using an adjustment LAYER, and I try to save the Photoshop image as a TIFF file, I find that when I open the saved TIFF image, the layer adjustment I'm seeing in the source Photoshop file has NOT been applied, and the image in the saved TIFF file looks just as dense as the original, unadjusted image in the Photoshop file!
    What am I doing wrong here?  I want to be able to save out that adjusted image as a TIFF file to use in designs, but I cannot seem to save it as a TIFF that actually CONTAINS or reflects these adjustments after having MADE the adjustments! 
    Whazzup?!!

    Well, I took the layered TIFF file you gave to me and opened it in Photoshop, reviewed the adjustment layer in there and its effect -- thanks: you get what I was trying to do -- and then saved it out as a flat TIFF image, and when I reopened it, voila!  it looked like the adjustment had indeed been applied.  So this IS a real head-scratcher indeed.
    I've now tried going back to my source file and doing the same thing.  One thing that I notice is that when I do the Save As of the TIFF with the adjustment layer in it (OR the PSD file, for that matter), when I go to Save YOUR file, the Layer Compression Options are grayed out, but when I go to Save MY file, the Layer Compression Options are active.  I've tried now saving both with RLE layer compression AND As a Copy ("discard layers and save a copy"), and neither works.
    I noticed, too, that your file had the layer below the adjustment layer still as a "Background," instead of a named layer, so I went back and applied an adjustment layer to a copy of my TIFF file, leaving the image in its layer as a Background layer, and still this did not work.
    The only other difference I saw between your TIFF file and mine, is that mine contained transparency, as I've silhouetted away a portion of the image to isolate the central image of the scanned engraving. But even when transparency is not a factor (i.e. I go back and start with a flattened, nontransparent image layer of my TIFF file with a single Background Layer, and I apply the adjustment layer to that, I get the compression options grayed out on Save, and STILL the saved TIFF image I get out of it has "reverted" to the unadjusted appearance.

  • 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?

  • Inverted grayscale images placed in Indesign

    I have customer files that were created in Indesign CS3 and CS4 with a placed, colored grayscale image on a colored background. The image is inverted but I cannot seem to replicate this. I know you can do this easily in Quark but how do you do this in Indesign? There is no invert effect.
    Thanks,
    Mike
    PS how do you subscribe to a post for email notification?

    That effect in Quirk was an accident... it tried to knock the placed image out of the background colour - 'dot for dot'!  Printers' nightmare...
    In InDesign (CS4) you use the direct/indirect selection tools to address the image or frame background. If you want a greyscale image on a coloured background you can set it to 'multiply', depending what type of image it is, you will need to decide whether to overprint at press is acceptable.
    If it is not acceptable, then add your background colour in Photoshop rather than InDesign for ease of control, where you can mix the colours if it is a photo.  If it is a solid shape then use a clipping path or alpha masking to knock out as required.

  • Is it possible to create a .pdf with BOTH color and grayscale images?

    Hello,
    I am in the final phases of a book project (4 years in the making!) that has both grayscale and color graphics. When I save as a .pdf via the Adobe PDF printer driver and distill, I end up with a .pdf that only has color graphics despite the fact that some images were grayscale to begin with. I'd like the grayscale images to remain graysale in the pdf. Is that possible?
    I am using older software framemaker 6.0 and acrobat & distiller 6.0 and am reluctant to change now, I will upgrade for a second edition, but not now.
    Thanks.

    Create the document in layers with the background on a seperate layer than the text. Export the PDF with"Create Acrobat Layers" selected (it will need to be at least version 1.5).
    Open the PDF in Acrobat, choose the background layer then Options>Properties>Initial State and under "print" choose "Never prints".

  • How to determine the correct K value within a grayscale image, quick?

    I frequently need to know specific grayscale values from grayscale images for further use in other applications.
    Problem: When opening the Color Picker the picked grayscale value is separated in CMYK. But I need it in K only.
    I actually have a workaround by comparing the RGB values while zeroing the CMY values and altering the K unless I found the correct value.
    Anyone knows an easier way to get a correct grayscale value in K (out of CMYK), quick?
    And btw. the K from the info panel does not show the correct value I need to know.

  • Using conversion to array to add 16 bit grayscale images

    Dear all,
    Usual disclaimers, first post, tried to search using a variety of terms, no luck, so posting a new question!
    I am trying to perform a running a verage of a 16 bit grayscale image. I do not have access to the Vision development module.  My 'workaround' is to grab the image, convert to array and then, using a shift register, to add this array to that acquired at the previous loop iteration. The problem I am having is that the shift register, despite being fed data in a 16 bit unsigned word formatt, returns 8 bit data. The add function is then trying to add 16 bit to 8 bit data and returns an empty array.
    Can anyone help? Surely it must be possible to use shift registers with arrays of 16 bit data?
    Any help appreciated!

    Shift registers work with all datatypes. Can you show us your code?

  • Best Way to Export PDF for Press w/ Grayscale Images

    Hi, we've been trying to move to a PDF based workflow for sending files to printers if possible so that all color conversion can take place at the final step of creating the PDF. This way, all images can remain RGB in their native color space.
    But I just had to create a PDF that had a mix of images in it. Some were typical RGB, some had already been converted to CMYK (probably US SWOP), and some were true grayscale images.
    When I created the PDF, I set it to convert all colors to the destination profile, which in this case was just US SWOP because the printer didn't have a more specific profile to suggest (most don't). It appears that the images converted properly, but the the grayscale images are using just the K channel (which I suppose is to be expected).
    A while back we printed a fully grayscale piece where all images were converted to a specially created SWOP profile that had modified GCR curves to have most of the data still represented by the black channel, but with some nice CMY thrown in as the tones deepened. The result was amazing. The images had no color cast, but were a nice rich grayscale. The printer was very impressed as well.
    A) So what would be the best workflow to incorporate mixed color images, and still have the grayscale images turn out nice & rich? Do I have to convert all images manually first (trying to avoid having to do this)?
    B) If the printer doesn't offer a profile, and probably doesn't fully understand or utilize color management, are we best to supply the PDF file converted to US Web Coated SWOP because that is what THEY would be most used to getting? This job, however, will be sheet-fed on a matte paper with a satin AQ.
    THANKS! Any tips would be greatly appreciated. Trying to refine our workflow here.

    I would love to learn more about how to choose an InDesign working color space when you don't know the end printer (or if the end printer is clueless); how to deal with Illustrator native files that will be placed in InDesign (RGB? CMYK? Embedded profile?); how to deal with pre-existing elements that may be in the wrong CMYK color space; and possibly the option of taking color management into your own hands if the printers aren't knowledgeable; etc.
    If the printer cannot provide an ICC, maybe they can state what print standard they use (GRACoL, SWOP). If you know that and the paper type, use your best judgement in selecting an ICC. Look to the IDEAlliance website, there are 2 SWOP profiles and one GRACoL profile that are good to use for coated stocks.
    As far as mixing existing CMYK with RGB, opinions may be varied. Let's say you have a job, moving to Coated GRACoL 2006. You place RGB images, US Web Coated SWOP v2 CMYK images, US Web Coated SWOP v2 Illustrator, and custom GCR CMYK rich black images.
    When these are placed into the GRACoL InDesign document, the default behavior is to preserve CMYK numbers. The GRACoL CMYK is assigned to all of the placed CMYK content.
    Now you output a PDF with the settings you described earlier. PDF/X-4, Convert to Destination, Document CMYK (GRACoL). Even though you had US Web and GCR originally, in the PDF it is all Device CMYK (when output from ID CS4). Furthermore any user must assume that all CMYK is GRACoL, because that is the Output Intent. Also, if the GRACoL is a decent representation of the print condition, you can soft proof everything accurately in Acrobat (and InDesign for that matter).
    If this PDF gets handed off to the printer, his duty is to RIP the CMYK and preserve numbers. The only number shifts will occur at the plating stage via plate calibration curves, which is not an ICC conversion.
    If a CMYK - CMYK conversion is necessary, the printer must get you on the phone and let you know that he is re-converting all your CMYK content. For him to do that without informing you is, well, nuts. You've already done the conversion yourself. Every conversion is (technically) damaging,
    Now assume that you output PDF/X-4 with no conversion. In that case, you have RGB and CMYK coexisting in the PDF output. Again, all CMYK should pass through the print RIP with numbers preserved. All RGB would be converted to the Output Intent already present in your PDF. If there is something wrong with that Output Intent, it's the printer's duty to get you on the phone and let you know. I say that because you, as a designer, have already soft proofed everything in the job in the GRACoL color space. If the printer wants to switch horses mid stream, he's got to let you know. (Side note – a printer taking a ownership of a special CMYK - CMYK conversion is highly unlikely. If they had a shop CMYK, they would have given it to you in the first place).
    In summary – it is the print industry standard to preserve incoming CMYK numbers. If a client gives me a job full of US Web Coated SWOP v2, I can't very well treat that the same as incoming RGB and start converting to a different CMYK. CMYK is already cooked. If you re-cook it it stands to get burned. The only time CMYK-CMYK is warranted is (a) when Total Ink Limit is a factor (uncoated) or (b) the color is so far off on the proof that re-cooking only stands to help it.
    What I WILL do is tell the client that they may get a better print result if they either supply RGB with no predetermined CMYK destination (I convert to press CMYK), or they use a different CMYK that more accurately describes the print condition.

  • How do I enhance a grayscale image--an x-ray?

    I have an x-ray that I would like to enhance so that I can see the nuances better. It is a grayscale image. The histogram is extremely narrow. The curves and levels do not seem to be nuanced enough...but I cannot figure out how to use filters and masks. Any direction you can give would be great.

    You can apply levels more than once, which may help. However so that it does not ruin your image, you could use the levels adjustment layer instead and create more than one.
    Another thing you could do is duplicate the layer and give it a multiply blend mode to darken or a screen blend more to lighten.

  • How to overlay color image over a grayscale image without IMAQ?

    I would like to display a color image over a grayscale image; I would like the color image look translucent. How would I do this without using IMAQ functions? I am currently displaying my grayscale image using Intensity Graph.

    > like the color image look translucent. How would I do this without
    > using IMAQ functions? I am currently displaying my grayscale image
    > using Intensity Graph.
    Transparency and overlays are really just arithmetic on the images. It
    is either done by the windowing system or by you. At the moment you
    can't set transparency on LV controls. You can set it on LV floating
    windows on some OSes, but then you will need to have the windows lined up.
    A more direct approach is to lighten or darken the color image elements
    based upon whether they will display over white, black, or a shade of
    gray. If the images don't have the same size pixels, this will have a
    first step of resampling th
    e images so they do. Then combine the pixels
    using the transparency you were going to apply to the color and the
    shade of gray beneath it. I'm being vague here because there are lots
    of physical models for combining colors.
    If I look in my paint program I see about fifteen, so this is where you
    get to make a choice and decide if black behind a red pixel is black, or
    dark red. It all depends on whether these are two transparent
    images(acetate sheets) backlit, or is it a transparency over a
    nontransmitting media like paper. Anyway, if you can be more specific
    about what you want, none of this is hard, typically just scaling the
    int32s, adding, and some sort of normalization.

  • Grayscale images too dark in InDesign

    Hello everyone,
    Whenever I place a grayscale image in my InDesign (CS 3) document, it looks far too dark (compared to what I want and what I prepared in Photoshop).
    These are the specs of the images: tif, 300 dpi, grayscale, 15% dot gain profile.
    I've tinkered with the color settings in InDesign, but nothing seems to change this. Only when I export the InDesign document to pdf and choose 'Convert to destination (preserve numbers) - Working CMYK (Coated Fogra27)' and choose to 'Include destination profile' the photos in the pdf document seem okay again.
    What am I doing wrong?
    Thanks for your help!
    johan

    The Gray profile you use in Photoshop gets ignored by ID even if you save it with the grayscale. ID puts the incoming grayscale's values on the black plate unchanged. Using a CMYK profile as the gray space in PS matches ID's color managementthe grayscale previews as it would print on the black plate of a CMYK press. You get a more consistent previewbut it has no affect on output.
    The only way you would get a conversion of black or grayscale values to a black+CMY color at output or export would be if the print destination CMYK profile were something other than the document CMYK profile. So if you assign Coated Fogra27 to your document, your printer would have to choose some other profile as the destination printer profile when she outputs separations for black to convert to CMYK.

  • Iphoto 9.6 rotation of grayscale images

    If I import grayscale images into iPhoto 9.6 (under Yosemite, in this case) (either Tiff or JPEG, 8- or 16-bit), iPhoto corrupts the images if I rotate them in iPhoto.
    To see it happen, I merely:
         Create a grayscale image (I use vuescan, but it will also happen if I save an image out of Photoshop CS6 as grayscale).
    Import it into iPhoto 9.6
    Rotate it (command-R).
    Now either toggle between thumbnail and full-size view or edit the image (again, I use photoshop here).
    The resulting image will be corrupted (probably either all-black or all-white, but it can show up other ways as well).
    Anyone else have this problem? The workaround is to import RGB files, but of course that's not ideal if your source files

    Thanks, Leonie; these are indeed taken with a photographic camera, but are single-channel. Previous versions of iPhoto have had complete support for grayscale images, and this version attempts to do the rotation but corrupts the image, so I interpret that behavior as a bug, rather than one of no support.
    Have you really been able to work with single channel gray scale images?  I know, that iPhoto and Aperture can work with gray scale images, as long as the gray scale is part of the color profile or an EXIF tag, but at least in Aperture you cannot do much with single-channel images, other then import and export them, or view them. The same goes for PSD files, or any file format with alpha channels and layers. As soon as transparency is involved, it cannot even be displayed correctly. That is even mentioned in the technical specifications. http://www.apple.com/aperture/specs/
    Aperture maintains but does not display layer and alpha channel information in PSD files.
    I suspect, that iPhoto has the same limitations, because both applications are sharing code and the unified photo library format.

  • 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.

  • Export as PDF with embedded profiles for Grayscale images

    Does InDesign CS6 export pages with Grayscale images as PDF with embedded profiles?
    Possible profiles, for instance:
    – Gamma 2.2
    – Dot gain 20%
    – Black Ink ISO Coated v2 (ECI)
    Export mode:
    – Acrobat 5 or higher
    – No color conversion
    – Embed all profiles
    Test by Acrobat Pro
    Advanced > Print production > Preflight > PDF analysis > List objects using ICC/Lab/Calibrated Color
    [The question is not about the export of Color images as Grayscales]
    Best regards --Gernot Hoffmann

    I wouldn't ever use different RGB profiles and different CMYK profiles and
    different Gray profiles in one doc – it's just necessary for tests.
    If you had a hypothetical case where your InDesign document's assigned CMYK profile and intended output was ISOcoated_v2_300_eci and you recieved grayscales for placement with different gray profiles assigned, I think you would have to make the conversion in Photoshop if you want the grayscales to be converted to your ISOcoated_v2_300_eci output intent space.
    So in this case I have a grayscale image with Dot Gain 10% assigned and you can see the 50% patch is reading as 50% in Info panel:
    If set my Working Gray space to the ISO Coated profile as above and do a Convert to Profile with the Destination set to Working Gray:
    The preview doesn't change but I get converted gray values—50% is now 44%:
    If I place the grayscale in an InDesign doc with ISOcoated_v2_300_eci assigned as the CMYK profile, the preview won't change (you have to turn on Overprint /Sep Preview), and the converted numbers will show in Separation Preview. The preview and numbers will also be unchanged in Acrobat if you export to default PDF/X-4

  • Best Workflow for Rich Grayscale Images on Press

    Hi, we're preparing a piece that uses mostly grayscale images and we want them to look as nice and rich as possible. So wondering about proper workflow to convert the images to CMYK using best percentages for nice, rich shadows, etc.
    What I've done so far is:
    1) Got a photo looking pretty decent as a grayscale image.
    2) Convert the image to CMYK using a custom profile I created similar to 'SWOP, 20%, GCR, Heavy' - except that I manually adjusted the Black Generation curve to remove most of the CMY from the highlight areas.
    3) Do any final levels adjustments to get the photo just right.
    4) Save the file embedding the profile.
    Now the photo looks good in Photoshop, and is very neutral (what we want). The darkest shadow areas are 95%-99% black, but with a good 40, 30, 30 mix of CMY. The highlight areas are black only up to about 16%, then color starts creeping in at proper ratios.
    NOW I'M A BIT FUZZY.
    - When I drop the photo into InDesign, the Prepress defaults strip the profile and convert to US Web Coated SWOP, BUT preserves the numbers. The photo takes on a cooler, more blueish tint. Is this to be expected?
    - We may not know the printer of the job ahead of time, and even if we do I've found many who don't fully understand color management and don't have a custom profile for their printer. What is safest in this case?
    - If we do get lucky and find out who the printer is, and they have a printer profile, how would we implement this?
    - Any other tips???
    THANKS!

    This may not be the most appropriate forum for your question. The separation you are using is done using the Custom CMYK engine, which is a legacy (pre-CM) mechanism in Photoshop that has no direct relationship to ICC color-managed workflows. Legacy questions may be better addressed to other forums.
    On the other hand, if, rather than use the Custom CMYK engine, you wish to separate your grayscale image to a CMYK ICC profile appropriate to your output conditions, the procedures are clearly outlined in "Real World Color Management", by Bruce Fraser, Chris Murphy and Fred Bunting. (Look for it on the Amazon site.)
    When the output conditions are not known, make sure to speak to the printers once they have been picked, and clearly communicate to them your concerns. You can provide a CMYK image file separated for US Web Coated (SWOP) v2, and ask them to reseparate it appropriately for their own press conditions. You could also provide the grayscale file, if they would rather have that one. In any case, make sure to tell them that you are looking for a high GCR.
    It's also a good idea to send them a properly color-managed proof (aimed at US Web Coated (SWOP) v2), and tell them to make sure to match it. Other than that, and in the absence of any information that is more detailed and specific, there's not much else you can do.
    >When I drop the photo into InDesign, the Prepress defaults strip the profile and convert to US Web Coated SWOP, BUT preserves the numbers. The photo takes on a cooler, more blueish tint. Is this to be expected?
    InDesign is
    i not
    converting the image. The North America Prepress 2 color presets use the "Preserve Numbers (Ignore Linked Profiles)" policy for CMYK. This policy
    i ignores
    the CMYK profile embedded in the image and
    i assigns
    the default CMYK profile instead. The image numbers are left untouched, but the appearance changes because the default profile (U.S. Web Coated (SWOP) v2) describes print conditions that differ from those established in your Custom CMYK profile.

Maybe you are looking for
